Left Subclavian Steel Syndrome
Left subclavian steel syndrome. The left subclavian artery is the aortic arch branch vessel most commonly affected by atherosclerosis. The condition has many potential causes some of which can be. Subclavian steal syndrome is a rare condition causing syncope or neurological deficits when the blood supply to the affected arm is increased through exercise.
The subclavian steal syndrome is a rare but important cause of syncope. Since recognition of this syndrome can lead to successful treatment a. Subclavian steal syndrome is a form of peripheral artery disease which is any condition where arteries outside of the heart become narrowed.
However if the cause of subclavian steal syndrome is determined to be atherosclerotic stenosis or occlusion of the proximal subclavian artery patients should be. Therefore it is not surprising that the left subclavian artery is involved with subclavian steal three times more frequently than the right subclavian artery is. Subclavian steal syndrome is a vascular disorder in which occlusion or stenosis of the subclavian artery proximal to the vertebral artery origin which is the subclavian artery causes altered vascular haemodynamics that result in retrograde blood flow in the ipsilateral vertebral artery toward the upper arm distal to the subclavian artery narrowing where decreased blood pressure had.
Subclavian steal is secondary to a proximal stenosing lesion or occlusion in the subclavian artery typically on the left. Pathophysiology of Subclavian Steal Syndrome. Subclavian steal syndrome is characterized by abnormal blood flow in the arteries.
Coronary subclavian steal syndrome CSSS occurs during left arm exertion when 1 the LIMA is used during bypass surgery and 2 there is a high grade 75 left subclavian artery stenosis or occlusion proximal to the ostia of the LIMA resulting in stealing of the myocardial blood supply via retrograde flow up the LIMA graft to maintain left upper extremity perfusion. Subclavian steal syndrome is treated using the same methods utilized in other forms of peripheral artery disease including lifestyle changes angioplasty and stenting surgical bypass and medications. The term subclavian steal describes retrograde blood flow in the vertebral artery associated with proximal ipsilateral subclavian artery stenosis or occlusion usually in the setting of subclavian.
