Abstract

Background and Objective: In normal development, the aortic arch (AA) gives 3 major branches: 1) Brachiocephalic trunk, 2) Left common carotid artery, and 3) Left subclavian artery. The abnormality of those AA branching is important for thoracic surgery consideration.  Although the abnormality of aortic arch branching has been reported in some races, this abnormality in Thai cadavers has never been investigated previously.   


Method: Dissections in this study were performed in Thai embalmed cadavers during teaching gross anatomy for Medical students of Ubon Ratchathani university.  The cadavers were carefully dissected thoracic region to investigate the anatomical structures of AA branching. This study was carried out from 10 female and 12 male cadavers.    


Result: From total 22 cadaveric samples, it was noted that only one male cadaver (58 years old, 4.55% of total investigated samples) has abnormality of the left vertebral artery obviously projected from the AA by running out between the left common carotid artery and left subclavian artery.


Conclusion: The information of this rare variation in the origin of vertebral artery from the AA is of the most importance to surgeons performing surgery in thoracic region. For radiologist, it is noted to avoid the misinterpretation of radiographs during performing angiography.
