The Anatomy of the Subclavian Artery
Aberrant subclavian artery is a rare vascular anomaly that is present from birth. It usually causes no symptoms and is often discovered as an incidental finding (such as through a barium swallow or echocardiogram ). Occasionally the anomaly causes swallowing difficulty ( dysphagia lusoria).
The subclavian artery is a large, major blood vessel that supplies oxygen -rich blood to the chest and upper limbs of the body. There are right and left subclavian arteries, and they received their name from the fact that they are both located under the clavicles, commonly known as the collar bones.

The 2022 edition of ICD-10-CM I65. 22 became effective on October 1, 2021. This is the American ICD-10-CM version of I65.
In subclavian stenosis, the artery is simply narrowed, leading to decreased blood flow beyond the area of blockage. When the subclavian blockage is severe, or if the artery is completely blocked, a condition called 'subclavian steal' can occur (Figure 4).
Branches of the Subclavian Artery The left and right subclavian arteries are located in the thorax (chest) underneath the clavicles (commonly known as the collarbones).
ICD-10 code I65. 2 for Occlusion and stenosis of carotid artery is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
The most common cause of subclavian artery stenosis is atherosclerosis but other causes include congenital abnormalities such as arteria lusoria (aberrant subclavian artery) or right sided aortic arch that can cause compression of the right subclavian artery leading to congenital subclavian steal syndrome,,.
A meticulous examination of segmental pulses and pressures, as well as judicious use of duplex ultrasonography, magnetic resonance angiography, computed tomography angiography, or conventional angiography can confirm the presence of subclavian stenosis.
The right subclavian artery is a branch of the brachiocephalic trunk and the left arises directly from the arch of the aorta. It lies posterior to the insertion of the scalenus anterior on the first rib. The subclavian vein runs parallel to the artery but in front of the scalenus anterior slightly at a lower level.
The subclavian artery is a paired arterial vessel of the thorax. The right and left arteries have different origins; the left subclavian artery originates directly from the aortic arch, while the right subclavian artery originates from the brachiocephalic trunk.
The main branches of the subclavian artery include the vertebral artery, the internal thoracic artery, the thyrocervical trunk, the costocervical trunk, and the dorsal scapular artery. Once the subclavian artery reaches the axilla, it becomes known as the axillary artery.
ICD-10 code I82. B22 for Chronic embolism and thrombosis of left subclavian vein is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
Stenosis, in general, refers to any condition in which a blood vessel -- such as an artery -- or other tubular organ becomes abnormally narrow.
