WORLD FEDERATION OF NEUROSURGICAL SOCIETIES Welcome from the Congress President

Dear Colleagues, dear Friends, I would like to welcome you to the XVI. WFNS World Congress of Neurosurgery in Istanbul, Turkey. It is a great honor to host the most in uential gathering of neurosurgeons and neuroscientists in this historic capital. With its bene cial location, connecting Europe and Asia, facilitating traveling to the “Olympics of Neurosurgery” and its welcoming atmosphere, Istanbul bridges the Orient and the Occident in the most natural manner, creating the perfect environment for the exchange of scienti c knowledge and friendship. Just as Istanbul unites in uences of its remarkable history with the young and modern vibe of a futuristic metropolis, the art of neurological surgery fuses established techniques with modern technology. The historical sites, ancient ruins of the Byzantine Empire, the traditional bazaars and the marvelous religious edi ces o er a one of a kind atmosphere, encapsulating the city and taking you on a unique journey through our history and culture. The breathtaking beauty of the turquoise sea of diamonds, the Bosporus, divides Asia and Europe, just to be joining the two beautiful shores in Istanbul. With great respect to our remarkable past, the city presents a modernized surrounding with its countless educational institutions, its developing infrastructure, and national and international shopping possibilities. We want to introduce you to the spark of the city and take you on an adventure you will always remember. Our mesmerizing social activities and surprises await you! Istanbul has always been the melting point of di erent cultural, religious, and political backgrounds and will now o er the stage for international neurosurgeons to get together in the name of science in de ance of political disputes around the world. It is in our power to pass our scienti c memento the next generation to let the spirit of neurosurgery evolve. Countless surgeons and scientists have honored this outstanding operation style and its sensitive approach. The earliest manifestation of interventions done to the skull were discovered when ancient skulls with arti cial holes were found. The establishment of the modern understanding of neurosurgery in the early 20th century evened out the scienti c journey for surgeons, who then operated in theaters and were respected for their craft. More and more young doctors were intrigued by the mysteries the brain was hiding. When nally, in 1955, a meeting of senior European neurosurgeons and representatives of 17 national neurosurgical societies took place in Brussels, with which the WFNS laid its rst milestone. The hard work of our teachers and their teachers is the reason we devote ourselves to go beyond limits and make the impossible possible. With great respect to the history of our profession, it is our duty to continue our mission and keep the Olympic re of Neurosurgery alive. Our union on behalf of neurosurgery clears the way for innovation in our eld. To aid this progression, we have to join forces, build up on previous knowledge and add new ideas, techniques and information to lead our minds to grow. The scienti c program of the World Congress 2017 o ers distinguished pre-congress courses, highly educational and fascinating presentations. I strongly believe these sessions, symposia and presentations will guide our young neurosurgeons, expanding their intellects and introducing them to paths for a brighter future. I am digni ed that in the face of current political disturbances and the internationally threatening terror, we have organized a state of the art congress, aiming to satisfy our highly-respected colleagues and dear friends. This is proof that science will always conquer fear and that we will always unite to carry out our profession with dignity and honor, regardless of boundaries we face. The amazing echo and positive response to our Congress with its 648 speakers from 90 countries despite the politically tumultuous times around the world, lls me with pride and shows that science will always nd its way. I owe gratitude to all my dear colleagues, who contributed immensely to the accomplishment of our congress. They worked sel essly for the success of the WFNS, and for that I am very grateful. On behalf of the Organising Committee, I wish you all an unforgettable time in Istanbul. May this congress lead to stronger friendships, inspirations and new international connections in the mission of our neurosurgical calling.

WORLD FEDERATION OF NEUROSURGICAL SOCIETIES Turkish Neurosurgical Society

Inherited Tradition to New Horizons

The Turkish Neurosurgical Society (TNS) is dedicated to advancing the specialty of neurological surgery in order to provide the highest quality of neurosurgical management and care in Turkey and beyond the borders.

The history of neurosurgery as a practice may be somewhat brief when compared to all other medical practices. During recent excavations in Aşıklı Höyük, 35 skulls - which had undergone a surgical procedure called “trepanation” - were found. However, it is di cult to tell whether these procedures were performed because of medical reasons or religious purposes such as to exorcise demons. Although modern history of neurosurgery began in Turkey in the 20th century, in Anatolia thousands of di erent neurosurgical touchstones form modern procedures.

Brief History of Pre-TNS Era

This era starts with Dr. Cemil Topuzlu (1868-1958) who should be considered the founder of modern surgery in Turkey. Dr. Topuzlu operated on many surgical cases for Pott’s disease, spinal and cranial injuries and brain abscesses. One of his cranial abscess cases was presented to the French Surgical Societies, which had most likely been the rst international neurosurgical presentation from Turkey.

In the years that followed, Dr. Alexander Kamburoğlu (?-1913), Dr. Garabe Yahoub (1865-1936), and Dr. Mim Kemal Öke (1884-1955) performed brain and spinal surgeries. Dr. Öke wrote the rst neurosurgery book in Turkish called “Dimağ ve Cümcüme Afetleri ve Tedavileri (Disasters of the Mind and Skull and Their Treatment)”. Dr. Abdulkadir Cahit Tuner went to Germany for formal studies, and became the rst neurosurgeon in Turkey in 1923. Until then all the neurosurgical procedures were performed by general surgeons.

In 1949, Dr. Hami Dilek founded the rst clinic with a specialization program in neurosurgery. Later on, Dr. Feyyaz Berkay, who received his education in the USA, established the rst neurosurgery clinic in Cerrahpaşa Medical School. Similarly, Dr. Bülent Tarcan, who was trained in the United Kingdom, returned to Turkey to establish the rst neurosurgery clinic in Çapa Medical School. These were followed by the establishment neurosurgery clinics in Hacettepe University in 1960, in Ankara University in 1965, and Ege University in 1967. Neurosurgery clinics were sprung and spread all over Anatolia, while Dr. Berkay was a trailblazer in the foundation of the rst Turkish Neurosurgical Society (TNS). The rst Neurosurgery Congress convened in 1971, but due to the political atmosphere of the time, there were limitations and it could not be carried out as expected or planned. Unfortunately, in 1980 the Turkish military coup closed down almost all independent societies such as the Turkish Neurosurgical Society.

Turkish Neurosurgical Society (TNS)

The Turkish Neurosurgical Society (TNS) is the main society of the neurosurgical specialty in Turkey. TNS was established in October, 1985. There are at present almost 1800 neurosurgeons in Turkey. Today, with its 1200 members, the TNS is the main organization for neurosurgeons in our country. Neurosurgery in Turkey has been improving every year: today, many neurosurgical departments perform state of the art surgical and medical procedures.

In 1959, Dr. Türkmen, who completed training at Philadelphia Medical Center, founded the Neurosurgery Department in Hacettepe University School of Medicine and left Turkey in 1960. Dr Nurhan Avman (1928-1968) directed this department until 1965. After leaving Hacettepe University, Dr Avman founded the Neurosurgery Department in Ankara University. Later on, Dr. Avman would be the person who initiated the Turkish neurosurgery journey. During this period, in Europe, a Turkish genius, M.Gazi Yaşargil M.D., made a great breakthrough in neurosurgery and developed the concept of microneurosurgery technique.

The rst neurosurgical society of Turkey was founded in Istanbul by 11 neurosurgeons in 1968; however, this society was closed as a result of the 1980 military coup. The Turkish Neurosurgical Society (TNS) was later founded in Ankara by Nurhan Avman, Ertekin Erasıl, Hamit Ziya Gökalp, Aykut Erbengi, Vural Bertan, Süleyman Sağlam, Özdemir Gürçay, Yücel Kanpolat, and Tunçalp Özgen in 1985, and with unanimous vote, Dr. Avman was elected the rst president of TNS. Subsequent 10 Organization

Turkish Neurosurgical Society XVI. World Congress of Neurosurgery presidents were Dr. Aykut Erbengi, Dr. Özdemir Gürçay, Dr. Tunçalp Özgen, Dr. Yücel Kanpolat, Dr. Osman Ekin Özcan, Dr. Ertekin Arasıl, Dr. Yamaç Taşkın, Dr. M. Nur Altınörs, Dr. M. Kemali Baykaner, Dr. Kaya Aksoy, Dr. M. Necmettin Pamir, Dr. Nurcan Özdamar, Dr. Ö. Selçuk Palaoğlu, Dr. Mehmet Zileli, Dr. Ethem Beşkonaklı, Dr. Murat Bavbek, Dr. Uğur Türe, Dr. Zeki Şekerci, Dr. Talat Kırış and Dr. Şükrü Çağlar.

This non-governmental society arose to this day from the day it became active, and it accelerated the publishing of scienti c studies. TNS is the most prominent scienti c and professional organization in its eld of activity. This society provides support for neurosurgeons all over the country and also encourages research activities among young trainees as well as funding scienti c projects. Nowadays, at least twelve scholarships for international courses are provided. The society also contributes to the specialty by merits awards for select scienti c studies, thereby enabling scienti c progress.

Under TNS, there are six education and training groups: (1) pediatric neurosurgery, (2) spinal and peripheral nerve surgery, (3) neuro-oncology surgery, (4) stereotactic, functional, pain and epilepsy surgery, (5) neurovascular surgery, and (6) neurotrauma. There are also 24 di erent boards under TNS such as social rights of membership, external relations, social responsibility projects, R&D activities, training of trainers, professional and personnel rights, and insurance system. They all together form a big structure, rapidly growing and becoming one of the most popular scienti c organizations of Europe and West Asia.

TNS is also an active member of the European Association of Neurosurgical Societies (EANS) and the World Federation of Neurosurgical Societies (WFNS). Therefore, TNS cooperates with these organizations in scholarship programs and establishing educational standards in the practice of neurosurgery. TNS is one of the best-organized national societies in Turkey. It has so far held 31 national congresses as well as numerous courses and hands-on workshops.

TNS organizes its annual national congress in April of every year. This year, the 31th National Neurosurgery Congress was organized in Antalya with at least 1400 participants. In addition, both national and International Basic Neurosurgery Courses are designed for residents in training and junior neurosurgeons. These consist of four annual courses, covering the key topics of Vascular Neurosurgery, Tumor, Neurotrauma/Functional Neurosurgery, and Spine/Peripheral Nerves. Hence, the course cycle takes four years to complete. Speci c course features include up to 10 hours of daily lectures, nearly 100 topics in each course. This year, as well as the TNS Congress, IBNC (Term II Course II, Neuro-oncology) was performed prior to congress sessions in Antalya. Today, these courses constitute some real success stories for TNS, with an increasing number of participants from all over the world.

TNS has 2 scienti c peer-review journals, both of which have been continuously in publication since 1989. The Turkish journal is called “Türk Nöroşirürji Dergisi” and the international journal “Turkish Neurosurgery”. Besides journals, TNS publishes a bulletin each year and publishes all the oral and poster presentations of the national congress.

To increase the quality of education, a Neurosurgical Board has been introduced by TNS. Members who pass the oral and written board examination are given a certi cate. Although there is not any o cial sub specialization for neurosurgery, several internal TNS organizations focus on certain aspects of neurosurgical care. Several meetings and symposiums are performed by these subgroups all year round.

Conclusion

The evolution of Turkish Neurosurgery may re ect a deep inherited tradition toward innovation and development. This makes us proud of what we hace accomplished and shared in such a short time period. Turkish Neurosurgery is thankful to Gazi Yaşargil, “Neurosurgery’s man of the century” and all other masters who contributed to - and totally changed - the perspective of Neurosurgery toward lesser “No Man’s Land”.

On behalf of the Turkish Neurosurgical Society, we are delighted and really excited to host you in Istanbul for the WFNS XVI World Congress of Neurosurgery. I hope that this event will promote the highest quality of neurosurgical practice all over the world.

M. Gazi YASARGIL

Professor M. Gazi Yaşargil was born on July 6. 1925 in Lice, Turkey. He completed high school in Ankara, Turkey, studied two semesters of medicine at the Friedrich Schiller University,

Jena, Germany (1944-1945), and completed his medical doctor degree at the University of Basel, Switzerland in September 1949. Following his rotation program in neuroanatomy, neurology, psychiatry, internal medicine and general surgery (1950-1952), he began his neurosurgical residency (1953-1960) at the University Hospital in Zurich, under Professor H. Krayenbühl,

Professor G. Weber and Professor E. Zander. In 1960 he became privat docent, in 1965 Assistant Professor of Neurosurgery, and in 1973 Ordinarius Professor and Chairman at the Department of Neurosurgery, University Hospital, Zurich, until his retirement in January 1993.

During the rst 12 years of his neurosurgery practice as resident, chief resident and docent (1953-1965), Professor Yaşargil was involved in developing percutaneous carotid, vertebral and orbital angiography. The detailed results have been published in ve books (1957-1965)

In 1957 he learned stereotactic surgery with Professor Th. Riechert and Professor Fr. Mundinger in the Department of Neurosurgery, Freiburg im Breisgau, Germany, and introduced the application of high-frequency coagulation techniques on patients with Parkinsonism and movement disorders, in the Department of Neurosurgery, University Hospital, Zürich. In 1961 he introduced the technique of spinal fusion using a telescopic screw device.

From October 1965 to December 1966 Professor Yaşargil spent 14 months in the animal laboratory at the Department of Neurosurgery, University of Vermont Medical Center Burlington, USA, (Chairman Professor R.M. Peardon Donaghy). He learned and improved microvascular suture techniques on peripheral arteries, and pioneered the application of microtechniques to the cerebral arteries of dogs, subsequently establishing reconstructive microvascular procedures and by-pass surgeries on patients.

On his return to Zurich in December 1966, he began to apply microtechniques to the entire eld of neurosurgery. Recognizing the phylogenetic and ontogenetic predilection sites of lesions of the central nervous system, and the distinct arrangement of the cranio-spinal cisterns, he developed transcisternal approaches to cranial and spinal lesions, and thus accomplished “pure lesionectomies” with the principle of complete elimination of the lesion at the rst surgical exploration. The outcomes and results on several thousand patients have been summarized and presented in eight monographs, namely; Microvascular Surgery 1967, Microsurgery applied to Neurosurgery 1968, and Microneurosurgery in 6 volumes 1984 – 1996

Between November 1994 and July 2013 Professor Yaşargil was active as Professor of Neurosurgery at the University of Arkansas for Medical Sciences, Little Rock, USA (Chairman Professor Ossama Al-Mefty), where a renowned center for microneurosurgery was created, and regular microsurgery courses for young colleagues were o ered.

In November 2013 Professor Yaşargil was appointed Professor of Neurosurgeryat Yeditepe University School of Medicine, Istanbul, Turkey, (Chairman Professor Uur Türe), where he continues to be actively involved in microneurosurgical practice, teaching, lecturing and preparing publications.

Award Winners

WORLD FEDERATION OF NEUROSURGICAL SOCIETIES The Scoville Award

The Scoville Award is to recognize a neurosurgeon whose work been instrumental in advancing the art and science of neurosurgery. The William Beecher Scoville Award was created in his memory by his family and was awarded for the rst time in 1993. Dr. Scoville was an inventive neurosurgeon who was well known for having developed the aneurysm clip that bears his name, as well as for his innovations in such areas as the surgery of seizure disorders and cervical disc diseases. Dr. Scoville was a world traveler and enthusiastic supporter of the WFNS. Not surprisingly, the criterion for the selection of an awardee is that the individual has notably advanced the art and science of neurosurgery and has also contributed to global communications among neurosurgeons, preferably through the WFNS. The rst ward was presented to Dr. Henk Verbiest in 1997 and the last one in 2009 to Dr. Robert F. Spetzler in Boston. The awards shall be presented at the Opening Ceremony of the World Congress. ALEXANDER N. KONOVALOV, M.D., Ph.D., has been the director of the esteemed Burdenko Neurosurgery Institute for 32 years and is the foremost gure in Russian neurosurgery. He brought neurosurgery in the former Soviet Union onto the world stage despite the isolationist policies of its former totalitarian regime. After the fall of the Soviet Union, he maintained the unity of the Eastern European neurosurgeons.

Ossama AL-MEFTY Professor of Neurosurgery, Brigham and Women’s Hospital Harvard School of Medicine, Boston - USA

It is one of the true professional honors of my career to date to introduce Dr. Ossama Al-Mefty today. He needs no introduction to this audience but I will make some personal remarks here as a tribute to him. He was born in Damascus, Syria in 1947. He graduated from medical school in 1972 and served his internship in Cleveland and a year in general surgery in Toledo, Ohio. From there, he matriculated into the neurosurgery program at West Virginia under Robert Nugent and John Fox for whom Dr. Al-Mefty has enduring respect. Even more signi cantly, he met his future wife Janice there. The details of Dr. Al-Mefty’s career journey are fascinating. He spent his rst 4 years in private practice in Richmond. The next step in his career was a most transformative one and further energized one of the great surgical minds we have seen in neurosurgery – he answered an advertisement to enter academic practice that took him and his growing family to Riyadh in Saudi Arabia. He did his rst petroclival meningioma there and continued a lifelong professional partnership with John Fox; he refers to this as “his time in the desert.” He proceeded to join the University of Mississippi under Robert Smith (on the advice of Steve Mahaley). Here the prodigious writing in skull base gathered pace, and the now seminal work on the posterior petrosal approach was published. He then moved to Loyola, where among other accomplishments he began one of the great skull base fellowships in the world -- the dissemination of a surgical philosophy and concept of doctoring will be everlasting. More on that later. He then accepted the position of the Chair at the University of Arkansas at Little Rock, where he took a small department and – if you know him, this isn’t surprising – through sheer force of will, individual brilliance, and work ethic, created an internationally renowned group whose intellectual core principle was the advancement of microsurgery and its technical mastery in all areas of our specialty. When I review this time, of his many decisions 2 faculty recruitments in adult neurosurgery stand out in particular: Ali Krisht, for how he enabled a young brilliant surgeon to grow; and Professor Yasargil, for how he was unafraid to bring this most brilliant surgeon to the United States. I was tremendously fortunate to do my fellowship with him in Arkansas having trained in Boston at the Brigham and Women’s Hospital, and I can tell you it was the best year of my neurosurgical life to date. What you know about his surgical ability is true, but it’s even more impressive right next to him - the raw technical ability matched with experience is indescribable. He has made a career of showing us what is possible, and it changed the arc of my own trajectory. What I also saw when working alongside him day in and day out is what a wonderful doctor and human being this man is. He is principled; he is gracious; he has a terri c sense of humor; and I know that my own career has been forever bettered by his in uence. A legion of former fellows will say the same. His sons have observed rightly so that his career has been marked by a relentless commitment to doing good – for his patients, pupils, mentors, or the unknown person around the world. We left together to come to the Brigham and Women’s Hospital under his good friend John Popp where his in uence and overarching guidance to all of us has been priceless. His philosophy of medicine and surgery has been instilled in all corners of our institution. His accomplishments are well known – he has helped us de ne the foundational principles of skull base neurosurgery and has shown not just me but the world what is possible in attacking deep-seated lesions safely. He is probably best known for meningioma and chordoma. He has written over 500 papers, 10 books, and has been ttingly honored by all of our societies. He co-founded the NASBS and the World Academy of Neurological Surgeons and the International Meningioma Society. His relationships internationally are vast and service to the world community well described. He counts many of you in this audience as trusted colleagues and friends. In all, his is as distinguished a career in medicine as one could imagine. He is married to the amazing Janice, and father to Kynda, Kaith, and Rami, and has 5 beautiful grandchildren – theirs is a wonderful and loving family who keep him in line, di cult as that is. His daughter is a successful attorney, and his sons will continue his neurosurgical legacy. We have our own mythology, our own pantheon in neurosurgery, and I think I speak for the World Federation in acknowledging his rightful place in it. To a world class intellect, man, mentor, doctor, surgeon, and, gratefully, friend – I present to you Dr. Ossama Al-Mefty.

WORLD FEDERATION OF NEUROSURGICAL SOCIETIES Abdessamad EL AZHARI Professor of Neurosurgery, Chairman of Neurosurgery Department, University Hospital Ibn Rochd, Casablanca - Morocco

Doctor Abdessamad El Azhari was born in Khouribga, Morocco, August 23, 1952. After having nished his primary, secondary, and High School in his home town, he moved to Rabat where he studied medicine at Mohammed V University of Rabat between 1973 and 1978. He graduated from the Medical School in 1979. Being attracted by a career at the university, he succeeded in the internship examination of the University Hospital Center. He prepared a thesis on the surgical treatment of exophthalmia. In 1981, he began his residency in neurosurgery in Casablanca, at the Department of Neurosurgery, Ibn Rochd Hospital Center, under the guidance of late Dr. El Faidouzi and later on under the supervision of Dr. M. Boucetta, Chairmen of the Neurosurgery Department in Casablanca respectively between 1981 and 1998. When he nished his residency in neurosurgery in Casablanca, he carried out a two-year fellowship in Rabat at the Department of Neurosurgery chaired by Dr. A. El Ouarzazi. He completed a third year fellowship in Paris at Hopital La Pitie-Salpetriere, at the Department of Neurosurgery chaired by Dr. J. Philippon. During his three years fellowship, Dr. El Azhari focused his training on cerebrovascular surgery and some aspects of functional neurosurgery like deep brain stimulation for Parkinson disease. Being back to Casablanca, he held a position of Assistant Professor in 1986, then Associate Professor in 1990, and Professor of Neurosurgery in 1993. In 1999, he was appointed Chairman of the Department of Neurosurgery at Ibn Rochd University Hospital Center in Casablanca. Since he began his career, Dr. El Azhari has been a hard worker, with skills in innovation, organization, and a great ability in bringing back together diverging opinions. These gifts enabled him to serve neurosurgery at the national, regional and international levels. At the national level, after being nominated as Chairman of the Neurosurgery Department, he succeed in a very few years in building a team of neurosurgeons able to manage patients from a very big city like Casablanca (more than 5 million inhabitants), but who are also able to improve neurosurgery by introducing microsurgical treatment of cerebral aneurysms, pediatric surgery, skull base surgery, and deep brain stimulation (DBS) to treat Parkinson disease. At the university, he understood the importance of a multidisciplinary approach of neurosurgery, by bringing together education and training in neurosurgery on the one hand, and clinical neurosciences on the other. The role he has played in innovating training programs enabled him to be involved as Chairman of the teaching methodology commission at the University, and later on as Director of the Department of Head Diseases. Dr. El Azhari has always answered the call when it comes to organizing and planning for the development of neurosurgery in the country or in the region. He was a founder member then president then past president of the Moroccan Society of Neurosurgery, a founder member of Hassan II Foundation for the Prevention and Cure of Nervous System Diseases, a founder member of the Federation of Maghrebian Societies of Neurosurgery, a founder member, president, and past president of the African Federation of Neurosurgical Societies. He has chaired various congresses held by these societies, and always actively participated in the organization of the scienti c programs of all neurosurgical and neurosciences meetings held in the country. At the regional and continental levels, Dr. El Azhari has spared no e ort to contribute in advancing African neurosurgery. He has supported and participated from the beginning in the WFNS Rabat regional training program. Although he was a founder member and president of the biggest regional African society of neurosurgery, AFNS (African Federation of Neurosurgical Societies), he has kept on calling for the uni cation of African neurosurgeons in a single continental body. He has been the rst to welcome the arbitrage of Prof. M. Samii and, using his skill of e ective negotiator, he has succeeded in convincing the members of the AFNS in 2013 in setting up the CAANS (Continental Association of African Neurosurgical Societies). His approach was hailed by all African colleagues. As a result, he was elected Honorary President of the CAANS during the Second CAANS Congress in Cape Town, July 26-28, 2016. At the international level, Dr. El Azhari has always been a strong supporter of the bid for Marrakech to host the rst World Congress in Africa. He has participated in its promotion with great enthusiasm, and during the organization of the congress, he held a very di cult task, namely the position of Chairman of the Scienti c Program Committee. He convinced us in the Organizing Committee of the Congress to cover the maximum amount of expenses for young African neurosurgeons, in order to encourage them in participating in the scienti c program. Dr. El Azhari is very active in the French-Speaking Society of Neurosurgery. He has been member of its Administrative and Scienti c Board between 2010 and 2015. He has held the position of Secretary General in this society since 2016. Dr. El Azhari is also an active member in many national, regional and international societies. He has organized and chaired many congresses held by these societies. His main elds of interest are: cerebrovascular surgery, functional neurosurgery, skull base neurosurgery, and pediatric neurosurgery. He has published 109 papers in national and international journals. He is the rst indigenous African neurosurgeon to be a nominee for the WFNS Medal of Honor in the history of the Federation. It is my pleasure, on behalf of the Medal of Honor Committee, to congratulate him, his wife, and their three children.

Ram Prasad (Robin) SENGUPTA XVI. World Congress of Neurosurgery Professor of Neurosurgery, M.Sc., FRCS (England), FRCS (Edin) Doctorate of Medicine, New Castle University, New Castle - UK

Professor Dr. Ram Prasad Sengupta M.Sc., FRCS (England), FRCS (Edin) Doctorate of Medicine, New Castle University, popularly known as Robin, was born on December 31, 1937 at Chittagong, India, now in Bangladesh. Born to poverty, he sold fruits and tutored toddlers to make ends meet and for schooling. After nishing high school, he did his intermediate Science in Chittagong and then moved to Calcutta in 1955. After considerable struggle, he got nally admitted to National Medical College, Calcutta. He completed his MBBS from Calcutta University in 1961. On May 1st 1961, Robin left for London after one month of marriage to his nearly six decade’s wife Mrs. Tapati Sengupta. During his rst house o cer position in Manchester, the nurses there called him‘Robin’ and the name stuck. His journey in Neurosurgery started with a ‘Locum’ job in the department of neurosurgery in New Castle General Hospital, UK and continued there as a consultant in neurosurgery, Mr. Sengupta did his FRCS from Edinburgh in 1967 and he also had a FRCS from England in 1969 and MSc from University of New Castle in 1976. After his training, Mr. Sengupta returned to settle down in India in 1971. While deciding what to do without a suitable opening in India, he got an o er from Prof. William Sweet to work with him at MGH, Harvard University. After a year with Dr. Sweet, he returned to New Castle and settled down there as a NHS Consultant. He travelled extensively to learn from great masters of neurosurgery. Of the many academic honours bestowed on him, Fellow Emeritus of the University of Durham (2001), Fellow of National Academy of Science (2009), Professor Emeritus of Neurosurgery, TN MGR University Chennai (2009), Honorary Doctorate of Medicine (New Castle University, 2016) are noteworthy. It is indeed a rare tribute to his international reputation in Neurosurgery that New Castle General Hospital named the Neurosurgery Theater as ‘The Robin Sengupta Theatre’ in 2003. An unknown Indian initially, Robin got his due from his home country with many public recognitions like “Neurosurgeon of the Millennium” awarded by the Neurological Society of India, “Vivekananda Samman” award from the former President of India APJ Abdul Kalam in 2016, ‘Loka Kalyan Award’ from Mrs. Manjula Chellar, Honorable Chief Justice of Kolkata High court to name a few. For his services to people with neurological disorders in the UK and India, he was appropriately recognized by the Queen of England with the award of “O ce of the British Empire (OBE)’, a rare distraction indeed. The BBC selected Mr. Sengupta from 20,000 surgeons in the UK along with representatives of other workers in the NHS to make a documentary “A Picture of Health” shown on BBC 1 on 22nd April 2003. Mr. Sengupta is a world renowned aneurysm surgeon and travelled around the globe to give lectures and operate on aneurysms. However, he enjoyed the most when he was invited to many cities in India to operate and give lectures. During these visits Mr. Sengupta was struck by the number of patients coming to him from Calcutta. It dawned on him then that to bring up the neuroscience of the highest order to Calcutta will be his ultimate challenge. He dreamt big and dreamt of a Neuroscience Institute in Calcutta. It is indeed a great achievement that he succeeded and Institute of Neuroscience, Kolkata (INK) was inaugurated by the Honourable President of India, Shri Pranab Mukherjee on 28th November 2014. ‘Robin’, Neurosurgery Ambassador of India, has been responsible for introducing many giants of neurosurgery to India and remains active till today sharing his time between New Castle and Kolkata. Dr. Sengupta is the rst Indian Neurosurgeon to be honoured by the prestigious Medal of Honour of WFNS. It is my pleasure and privilege to congratulate him and his family on behalf of the WFNS.
