  • Historia De La Cirugía De Epilepsia
    Artículo de revisión Historia de la cirugía de epilepsia Alonso-Vanegas MA,1 Bramasco Avilez A,2 Moreno Jiménez S1 RESUMEN Uno de los grandes triunfos de la neurocirugía moderna es el hecho de que muchos pacientes con epilepsia puedan ser curados, o presentar una mejoría significativa de esta enfermedad devastante, mediante diversos procedimientos quirúrgicos, con una morbimortalidad muy baja. La cirugía de epilepsia en su connotación actual se desarrolla gracias a la introducción de tres grandes avances para la medicina: anestesia, antisepsia y la localización cerebral. Esta revisión se enfoca en el trabajo visionario de numerosos investigadores desde los trabajos de Paúl Broca, quien establece la relación existente entre la afasia y el lóbulo frontal hasta la localización estereotáctica de áreas epileptógenas por Talairach y Bancaud. En este recorrido se analizan los trabajos de Hitzig y Fritsch, quienes publican sus resultados sobre estimulación cortical en perros; de Horsley, quien realiza cirugía de epilepsia con localización clínica del área epileptogénica; de Krause, quien realiza la primera estimulación cortical en humanos buscando localizar los focos epileptógenos; de Penfield, quien inicia las resecciones del lóbulo temporal para el manejo de la epilepsia, así como el desarrollo del electroencefalograma por Berger. Debido entonces al esfuerzo e ingenio de grandes hombres estamos hoy día más cerca de una solución definitiva, o al menos una mejoría importante para el paciente epiléptico, y la cirugía de epilepsia ha pasado a ocupar un lugar sobresaliente en los anales de la medicina. Palabras clave: cirugía de epilepsia, pioneros de la cirugía de epilepsia, Víctor Horsley, Wilder Penfield, Fedor Krause, Otfrid Foerster, historia de la epilepsia.

  • Fedor Krause: the First Systematic Use of X-Rays in Neurosurgery
    Neurosurg Focus 33 (2):E4, 2012 Fedor Krause: the first systematic use of x-rays in neurosurgery ALI M. ELHADI, M.D., SamUEL KALB, M.D., NIKOLAY L. MARTIROSYan, M.D., ABHISHek AGRAWAL, M.D., anD MARK C. PREUL, M.D. Division of Neurological Surgery, Barrow Neurological Institute, St. Joseph’s Hospital and Medical Center, Phoenix, Arizona Within a few months of Wilhelm Conrad Röntgen’s discovery of x-rays in 1895, Fedor Krause acquired an x-ray apparatus and began to use it in his daily interactions with patients and for diagnosis. He was the first neurosurgeon to use x-rays methodically and systematically. In 1908 Krause published the first volume of text on neurosurgery, Chirurgie des Gehirns und Rückenmarks (Surgery of the Brain and Spinal Cord), which was translated into English in 1909. The second volume followed in 1911. This was the first published multivolume text totally devoted to neurosur- gery. Although Krause excelled in and promoted neurosurgery, he believed that surgeons should excel at general sur- gery. Importantly, Krause was inclined to adopt technology that he believed could be helpful in surgery. His 1908 text was the first neurosurgical text to contain a specific chapter on x-rays (“Radiographie”) that showed roentgenograms of neurosurgical procedures and pathology. After the revolutionary discovery of x-rays by Röntgen, many prominent neurosurgeons seemed pessimistic about the use of x-rays for anything more than trauma or fractures. Krause im- mediately seized on its use to guide and monitor ventricular drainage and especially for the diagnosis of tumors of the skull base.

  • Psychomotor Seizures, Penfield, Gibbs, Bailey and The
    View Point Psychomotor seizures, Penfi eld, Gibbs, Bailey and the development of anterior temporal lobectomy: A historical vignette Prasad Vannemreddy, James L. Stone, Siddharth Vannemreddy, Konstantin V. Slavin Department of Neurosurgery, University of Illinois at Chicago, Chicago, IL, USA Abstract Psychomotor seizures, referred to as limbic or partial complex seizures, have had an interesting evolution in diagnosis and treatment. Hughlings Jackson was the first to clearly relate the clinical syndrome and likely etiology to lesions in the uncinate region of the medial temporal lobe. With the application of electroencephalography (EEG) to the study of human epilepsy as early as 1934 by Gibbs, Lennox, and Davis in Boston, electrical recordings have significantly advanced the study of epilepsy. In 1937, Gibbs and Lennox proposed the term “psychomotor epilepsy” to describe a characteristic EEG pattern of seizures accompanied by mental, emotional, motor, and autonomic phenomena. Concurrently, typical psychomotor auras and dreamy states were produced by electrical stimulation of medial temporal structures during epilepsy surgery by Penfield in Montreal. In 1937, Jasper joined Penfield, EEG was introduced and negative surgical explorations became less frequent. Nevertheless, Penfield preferred to operate only on space occupying lesions. A milestone in psychomotor seizure diagnosis was in the year 1946 when Gibbs, at the Illinois Neuropsychiatric Institute, Chicago, reported that the patient falling asleep during EEG was a major activator of the psychomotor discharges and electrographic ictal episodes becoming more prominently recorded. Working with Percival Bailey, Gibbs was proactive in applying EEG to define surgical excision of the focus in patients with intractable psychomotor seizures. By early 1950s, the Montreal group began to clearly delineate causative medial temporal lesions such as hippocampal sclerosis and tumors in the production of psychomotor seizures.
