There are two such vessels within the human body the left subclavian vein and the.

Subclavian anatomy. The subclavian vein scv is the major venous channel that drains the upper limb. Gross anatomy origin and course the subclavian vein starts at the crossing of the lateral border of the 1st rib. The first part extends from the origin up to the muscle.

It then arches cephalad posterior to the medial. The third extends from the lateral margin of the muscle to the. It ends at the first ribs lateral edge.

The aortic arch on the right and the brachiocephalic trunk on the left. Each subclavian artery is split into three parts in relation to the scalenus anterior muscle. The second lies behind this muscle.

The left subclavian artery branches off the arch of the aorta. The subclavian arteries are a pair of large arteries in the thorax that supply blood to the thorax itself head neck shoulder and arms. At this point it turns into the axillary artery.

The first portion extends from the origin of the vessel to the medial border of the scalenus anterior. In order to facilitate the description each subclavian artery is divided into three parts. The subclavian vein is an extension of the axillary vein that originates at the outer border of the first rib.

Fistulae between the subclavian artery and esophagus are extremely rare and anatomically possible in the presence of an anomalous right subclavian artery which arises from the proximal descending thoracic aorta and courses behind the esophagus to supply the right arm.
