Subclavian steal syndrome (SSS), also called subclavian steal steno-occlusive disease, is a medical condition characterized by retrograde (reversed) blood flow in the vertebral artery or the internal thoracic artery. This reversal occurs due to proximal stenosis (narrowing) or occlusion of the subclavian artery.
Subclavian steal syndrome occurs when there is occlusion or stenosis of the subclavian artery at a point before the branching of the vertebral artery. [7] This can cause blood to flow the wrong way through the vertebral artery into the distal subclavian artery, allowed by the reduced pressure. [7] [8]
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.
Besides, overuse injury of the upper limbs causes swellings, small bleeding, and subsequent fibrosis which would cause the thrombosis of the subclavian vein, leading to Paget–Schroetter disease or effort-induced thrombosis. [7] TOS can be related to cerebrovascular arterial insufficiency when affecting the subclavian artery. [8]

Stenosis (from Ancient Greek στενός (stenós) 'narrow') is the abnormal narrowing of a blood vessel or other tubular organ or structure such as foramina and canals. It is also sometimes called a stricture (as in urethral stricture ).
[8] [9] In subclavian steal syndrome, blood is "stolen" from the vertebral artery on the affected side to preserve blood flow to the upper limb. Subclavian steal syndrome results from a proximal stenosis (narrowing) of the subclavian artery, one of arteries originating off of the aortic arch. Subclavian steal syndrome has potential to affect ...
Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex.
