Variations of the branches of aortic arch are due to alteration in the development of certain branchial arch arteries during embryonic period. Knowledge of these variations is important during aortic instrumentation, thoracic, and neck surgeries. In the present study we observed these variations in fifty-two cadavers from Indian populations. In thirty-three (63.5%) cadavers, the aortic arch showed classical branching pattern which includes brachiocephalic trunk, left common carotid artery, and left subclavian artery. In nineteen (36.5%) cadavers it showed variations in the branching pattern, which include the two branches, namely, left subclavian artery and a common trunk in 19.2% cases, four branches, namely, brachiocephalic trunk, left common carotid artery, left vertebral artery, and left subclavian artery in 15.3% cases, and the three branches, namely, common trunk, left vertebral artery, and left subclavian artery in 1.9% cases.

In human beings the most common branching pattern of the aortic arch was its division into three great vessels ie the brachiocephalic trunk, left common carotid artery and the subclavian artery. The vertebral arteries arise from the superior aspect of the first part of the subclavian artery. In present case, a left vertebral artery arose from the aortic arch as fourth branch was found. The diameter of left vertebral artery at its origin was 6 mm as compared to the right vertebral artery, which has diameter of 3.5 mm at its origin. In this case left sixth dorsal intersegmental artery might have persisted as first part of vertebral artery hence left vertebral artery arising from arch of aorta. Knowledge of the variations in branching pattern of the aortic arch is important in the diagnosis of intracranial aneurysm after subarachnoid haemorrhage.J. Biomed. Sci. 2015, 2(3):21-23.

Abstract Background and aims: Study of branching pattern of arch of aorta and its variation is very significant. This study helps in avoiding the surgical, accidental injuries of blood vessels during cardiovascular surgeries and radiological procedures. Present study is aimed at finding out the branching pattern of arch of aorta, variations of its incidence, clinical significance and to correlate its embryological basis. Materials and methods: Present study was conducted on 30 formalin fixed cadavers, which were allotted to the undergraduate students of Bangalore Medical College and Research Institute. A comparative analysis was done with previous studies. Results: Usual three-branched aortic arch was found in 23 cadavers (76.66% ); variations were found in seven cadavers (23.33% ); 10% presented left vertebral artery arising directly from the arch of aorta; 6.66% presented common trunk of left vertebral artery and left subclavian artery; 3.33% presented thyroidea ima artery arising from the arch; 3.33% presented common trunk of brachiocephalic trunk and left common carotid artery. Conclusion: Variations observed in present study were in par with the variations observed by previous studies. Although anomalous origins of the aortic arch branches very rarely produces clinical symptoms but their knowledge is necessary for operating surgeons and interventional radiologist to avoid complications in the thorax, head and neck region.

Abstract OBJECTIVE: We performed a systematic microanatomical study of the occipital artery (OA) and its branches to describe the course, diameter, and branches of this vessel as well as the presence and pattern of anastomotic channels between the OA and the vertebral artery. METHODS: Twelve occipital arteries (6 adult cadaveric heads injected with colored latex) were studied using the surgical microscope. Particular attention was given to the course and branching pattern of the artery as well as the presence and type of anastomotic channels between the occipital artery and vertebral artery. RESULTS: Based upon anatomical considerations, the course of the occipital artery was divided into three segments. The first, or digastric segment, extends from the origin to the exit off the occipital groove of the mastoid process. The second segment, or suboccipital, extends from the occipital groove to the superior nuchal line. The third, or terminal segment, corresponds to the subgaleal segment just above the superior nuchal line up to the vertex. Two main descending branches of the second segment or suboccipital were identified. The superficial descending branch (SDB) runs between the splenium capitis and semispinalis capitis while the deep descending branch (DDB) enters the suboccipital triangle. Anastomotic vessels between one of these two descending branches and branches of the vertebral artery were found in 11 out of the 12 OAs dissected (91%). CONCLUSION: Detailed knowledge of the OA anatomy is helpful in choosing this vessel as a donor for extra-intracranial bypasses. More importantly, knowledge and understanding of the type and pattern of anastomoses between the OA and the vertebral artery are critical to avoid disastrous complications (i.e., posterior circulation stroke) during embolization of vascular or neoplastic processes fed by distal OA branches.

Abstract Background: The knowledge of normal and variant anatomy of vertebral artery is important for the interpretation of vascular radiology and in performing safe vascular procedures like repair of aneurysms, excision of craniocervical junction masses & vertebral endarterectomy. Aim: To find out incidence of left vertebral artery of aortic origin in North Indian population. Materials & Method: During routine dissection of thoracic region, an anatomical variation of origin of left vertebral artery of aortic origin was observed in adult male cadaver. To find out incidence of left vertebral artery of aortic origin in North Indian population, Radiological study was done on 100 patients [34 female + 66 males] who were advised computed tomography of neck & thorax for various indication. Diameter of left vertebral artery at origin from arch of aorta and where it entered foramen transversarium was measured. Length of VI segment i.e. from its origin to where it entered foramen transversarium was also measured. Result: Out of 100 patients, left vertebral artery of aortic origin was observed in 4 patients. Conclusion: Aortic origin of vertebral artery is of diagnostic importance prior to surgery in neck & chest regions. Cadaveric metrological studies are also helpful to design aortic stent

Background: Knowledge of the branching pattern of arch of aorta is important in avoiding surgical and accidental injuries during aortic instru- mentation, thoracic and neck surgeries. Subjects and Methods: The present study is based on dissections that were performed on 50 properly embalmed human cadaver specimens. The anatomical variations of arch of aorta and its branches, diameter of its branches at site of origin and distance of each branch from the point of origin to median plane were measured. Results: The usual three branched pattern of arch of aorta was found in 36 specimens (72%). The common trunk for both brachiocephalic trunk and left common carotid artery was present in 10 specimens (20%). In 2 specimens (4%), the arch gives four branches, left vertebral artery being additional branch. In 1 specimen (2%), the arch gives three branches namely; common trunk for brachiocephalic trunk and left common carotid artery, left vertebral artery and left subclavian artery. In 1 specimen (2%), the arch gives three branches namely; brachiocephalic trunk, left common carotid artery and common trunk for left vertebral artery and left subclavian artery. Conclusion: The results in this study provide significant information vital for anatomists, cardiovascular surgeons and radiologists.
