A Case Report of Variation in Subclavian Artery Branches

The subclavian artery is a major branch of the Aorta. In the left, the subclavian artery arises from Aortic arch and in the right it arises from the Brachiocephalic trunk. This artery passes from the subclavian groove on the first rib and continues as Axillary artery. The subclavian artery has several branches that supply chest wall, Thyroid gland and cervical regions. Several variations about the subclavian artery and it`s branches were have been reported. In this case, from the first part of this artery, we found a common trunk that gives the ascending cervical, Transvers cervical, Suprascapular and Dorsal scapular arteries. The inferioe thyroid artery was absent.
