摘要：Branches of aortic arch usually are brachiocephalic trunk, left common carotid artery and left subclavian artery from right to left direction. Arch of aorta show more variations in branching patterns. One among which is origin of only two branches in which brachiocephalic trunk and left common carotid artery arise together as a common trunk and other branch is left subclavian artery. The variations occur due to abnormal development of arch of aorta. During routine dissection of superior mediastinum of thoracic region, we have found the left common carotid artery and brachiocephalic trunk was arising from the arch of aorta as a common trunk. These kinds of variations are very rare and knowledge of which is very important for neck surgeons, cardiologists and interventional radiologists while doing surgeries and instrumentation procedures.
