Subclavian Steal Syndrome

چکیده
The Subclavian Steal Syndrome is a condition that results from the stenosis or occlusion of the subclavian artery proximal to the origin of the vertebral artery. The blockage causes the reversal of the normal direction of blood flow in the vertebral artery which is termed the "steal", because it steals blood from the cerebral circulation. Blood is drawn from the contralateral vertebral, basilar or carotid artery regions into the low-pressure ipsilateral upper limb vessels. Although a relatively uncommon disease, it represents a condition which mimics many conditions often treated by chiropractors and osteopaths. The term subclavian steal syndrome is applied when reversed vertebral artery flow causes cerebral ischaemia with associated symptoms of vertebrobasilar hypoperfusion and/or symptoms of brainstem or arm ischaemia. This syndrome exists as an important consideration in the differential diagnosis of cerebral and brachial ischaemia.

Right subclavian steal associated with aberrant right subclavian artery.
The subclavian steal syndrome is a well-recognized clinical and radiographic entity that involves the left subclavian artery far more commonly than the right. Atherosclerotic stenoses are the most common underlying cause [1-3]. Right subclavian stenosis with associated steal is markedly less common. Although an aberrant right subclavian artery is one of the most common anomalies of the great ve...

patients are asymptomatic.1 The syndrome of subclavian steal caused by an occlusive lesion of the aberrant subclavian artery is a rare clinical finding.1-4 This syndrome results from the abnormal flow of blood due to the occlusion in the subclavian artery proximal to the origin of the vertebral artery. Blood flow through the vertebral artery is consequently reversed and the subclavian one thus ...

Subclavian steal syndrome is known as reverse flow from vertebral artery to subclavian artery due to occlusion of proximal subclavian artery. Occlusive process leading to syndrome is common in left subclavian artery. Coronary-subclavian steal syndrome may happen by reverse flow in left internal thoracic artery with occlusion in subclavian artery of patients who were performed coronary artery by...

Coronary subclavian steal syndrome refers to decreased or reversed internal mammary artery flow, which causes angina related to severe subclavian steno-occlusive disease in patients with in situ internal mammary-to-coronary artery graft. We present a 48-year-old man with cerebrovascular and peripheral artery disease and the first case in the literature of a saphenous vein graft-coronary-subclav...

The authors present two cases of bilateral subclavian steal syndrome, a rare condition that does not commonly cause neurovascular symptoms. Lateralizing hemispheric events occur usually with carotid lesions. Vertebral-basilar insufficiency is three times more common in bilateral than in unilateral subclavian steal syndrome. Arm-exercise-induced brain-stem dysfunction is rare, and is seen only i...
