aneurysmal dilatation ( aberrant subclavian arterial aneurysms) of the proximal portion of an aberrant right subclavian artery can occur, a pouch-like aneurysmal dilatation is called a diverticulum of Kommerell. 1). On the right, the subclavian artery arises from the brachiocephalic trunk. It goes behind the trachea (windpipe) and the esophagus (tube that connects the mouth to the stomach), and then turns towards the right shoulder and arm. A leftsided PDA courses from the left subclavian artery to the origin of the left pulmonary artery. The subclavian artery rises from its origin in the chest cavity and passes a short distance into the root of the neck before continuing into the axillary artery. There are five branches from the subclavian artery : The cephalic vein traverses the lateral side of the arm from the hand to the shoulder. The left subclavian artery is the fifth branch of the aorta and the third branch from the arch of the aorta. Patients are often (60-80%) asymptomatic. The surg. Course and branches.

Carotid ultrasound is crucial to the diagnosis and treatment of extracranial vascular disease. The presence of an aberrant right subclavian artery is a known normal variant of the aortic arch anatomy, with a reported incidence of 0.2-4.4 percent. . It branches from the subclavian artery, where it arises from the posterosuperior portion of the subclavian artery. 3 Course The PDA is visualized in its entirety, to determine its course. The left subclavian artery branches directly from the aortic arch, whereas the right subclavian artery arises from the brachiocephalic trunk, also known as the innominate artery (Figure 32-1).The subclavian artery courses posteriorly to the clavicle and travels between the anterior and middle scalene muscles of the lateral neck.

About 3% of the general population has subclavian artery disease, and in those with PAD, the percentage is 11%. Dysphagia due to an aberrant right subclavian artery is termed dysphagia lusoria, although this is a rare complication. Possible catastrophic clinical consequences necessitate prompt rectification of the underlying disease and risk factors. 5 This artery can pass behind the esophagus, between the trachea and esophagus .
