The origin of the left vertebral artery was from the aortic arch. On the right side, no thyrocervical trunk was found. The two branches which normally originate from the thyrocervical trunk had a different origin. The transverse cervical artery arose directly from the subclavian artery and suprascapular artery originated from the internal thoracic artery. This variation provides a short route for posterior scapular anastomoses. An awareness of this rare variation is important because this area is used for diagnostic and surgical procedures.

  • Ascending and Descending Thoracic Vertebral Arteries
    CLINICAL REPORT EXTRACRANIAL VASCULAR Ascending and Descending Thoracic Vertebral Arteries X P. Gailloud, X L. Gregg, X M.S. Pearl, and X D. San Millan ABSTRACT SUMMARY: Thoracic vertebral arteries are anastomotic chains similar to cervical vertebral arteries but found at the thoracic level. Descending thoracic vertebral arteries originate from the pretransverse segment of the cervical vertebral artery and curve caudally to pass into the last transverse foramen or the first costotransverse space. Ascending thoracic vertebral arteries originate from the aorta, pass through at least 1 costotransverse space, and continue cranially as the cervical vertebral artery. This report describes the angiographic anatomy and clinical significance of 9 cases of descending and 2 cases of ascending thoracic vertebral arteries. Being located within the upper costotransverse spaces, ascending and descending thoracic vertebral arteries can have important implications during spine inter- ventional or surgical procedures. Because they frequently provide radiculomedullary or bronchial branches, they can also be involved in spinal cord ischemia, supply vascular malformations, or be an elusive source of hemoptysis.

  • An Unusual Origin and Course of the Thyroidea Ima Artery, with Absence of Inferior Thyroid Artery Bilaterally
    Surgical and Radiologic Anatomy (2019) 41:235–237 https://doi.org/10.1007/s00276-018-2122-1 ANATOMIC VARIATIONS An unusual origin and course of the thyroidea ima artery, with absence of inferior thyroid artery bilaterally Doris George Yohannan1 · Rajeev Rajan1 · Akhil Bhuvanendran Chandran1 · Renuka Krishnapillai1 Received: 31 May 2018 / Accepted: 21 October 2018 / Published online: 25 October 2018 © Springer-Verlag France SAS, part of Springer Nature 2018 Abstract We report an unusual origin and course of the thyroidea ima artery in a male cadaver. The ima artery originated from the right subclavian artery very close to origin of the right vertebral artery. The artery coursed anteriorly between the common carotid artery medially and internal jugular vein laterally. It then coursed obliquely, from below upwards, from lateral to medial superficial to common carotid artery, to reach the inferior pole of the right lobe of thyroid and branched repeatedly to supply the anteroinferior and posteroinferior aspects of both the thyroid lobes and isthmus. The superior thyroid arteries were normal. Both the inferior thyroid arteries were absent. The unusual feature of this thyroidea ima artery is its origin from the subclavian artery close to vertebral artery origin, the location being remarkably far-off from the usual near midline position, and the oblique and relatively superficial course. This report is a caveat to neck surgeons to consider such a superficially running vessel to be a thyroidea ima artery.

However, significant pattern variations exist. Characterizing SCA branches and its relationships to landmark structures like the anterior scalene muscle (ASM) is important in surgery. Computed Tomography Angiograms from 55 patients were retrospectively analyzed using Aquarius iNtuition. Measurements were taken of: distance of origin of SCA branches from the aorta and the ASM-VA origin distance. Only 13 SCAs (12.9%) exhibited the highest prevalence in typical branching pattern. VA originated 1st in 80.2% of SCAs, with ITA arising 2nd (41.3%), TCT 3rd (47.3%), CCT 4th (43.6%) and DSA 5th branch (56.9%). Average VA-ASM distance was 14.14mm with 94.9% of VAs originating within 30mm proximal to the medial border of ASM.

On the left side, the ITA branched from the subclavian artery as a common trunk with the thyrocervical trunk. The left LCB flew into the collateral branch of the fifth intercostal artery after reaching the upper end of the sixth rib and after exiting the left ITA at the upper part of the first rib. The left ITA was disconnected near the second rib because it had been used for coronary artery bypass surgery. The right ITA arose from the anterior surface of the right subclavian artery just after the right ITA diverged from the brachiocephalic artery. The right LCB reached the upper end of the fifth rib and flew into the collateral branch of the fourth intercostal artery. The right ITA descended along the back of the costal cartilages as usual.

Santos, M. Fernandes, S.F. de Souza, C.A. dos Santos-Sousa, Y.K. de Carvalho Federal University of Acre, Rio Branco, Brazil [Received: 20 March 2019; Accepted: 19 April 2019] The giant armadillo (Priodontes maximus) is found in diverse habitats from South America. A female adult giant armadillo with a body mass of 45 kg was used. The animal was a victim of trampling on highway AC-40, at 70 km, near the municipality of Capixaba-Acre and the corpse donated to the Animal Anatomy Laboratory at Federal University of Acre (UFAC). The arterial system was filled with natural latex via the thoracic aorta in a direction opposite the blood flow to facilitate the description of the aortic arch and its side branches. The study was approved by CEUA/UFAC – no. 053/2015 and SISBIO no. 47124-1. The aortic arch issued side groups, which had the following sequence: brachycephalic trunk, left carotid artery, left subclavian artery. The brachycephalic trunk forked forming the right subclavian artery and the right common carotid artery. The arrangement allowed the whole carotid blood supply to the brain and surrounding structures present in the animal’s head. The subclavian arteries, of homologous way, origi- nated the arteries: vertebral, thoracic, and cervical costocervical trunk.
