The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax. On the left side of the body, the subclavian comes directly off the aortic arch , while on the right side it arises from the relatively short brachiocephalic artery when it ...

Aberrant subclavian artery, or aberrant subclavian artery syndrome, is a rare anatomical variant of the origin of the right or left subclavian artery. This abnormality is the most common congenital vascular anomaly of the aortic arch , [ 1 ] occurring in approximately 1% of individuals.
The brachiocephalic artery, brachiocephalic trunk, or innominate artery is an artery of the mediastinum that supplies blood to the right arm, head, and neck. [1] [2] It is the first branch of the aortic arch. [3] Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. [4]

The procedure involves connecting a branch of the subclavian artery or carotid artery to the pulmonary artery. In modern practice, this procedure is temporarily used to direct blood flow to the lungs and relieve cyanosis while the infant is waiting for corrective or definitive surgery when their heart is larger.
In a third variant, the brachiocephalic artery splits into three arteries: the left common carotid artery, the right common carotid artery and the right subclavian artery; this variant is found in an estimated 7% of individuals. [16] In rare cases, the thyroid ima artery, a variant artery supplying the thyroid gland may arise from the aortic arch.
The internal thoracic artery arises from the anterior surface of the subclavian artery near its origin. [2] [3] It has a width of between 1-2 mm. [4] It travels downward on the inside of the rib cage, approximately 1 cm from the sides of the sternum, [3] and thus medial to the nipple. It is accompanied by the internal thoracic vein.
