Subclavian steal syndrome is a syndrome associated with steno-occlusive pathology of the proximal subclavian artery with subsequent reversal of flow in the ipsilateral vertebral artery. It is characterized by flow reverse in the vertebral artery to supply the vascular bed distal to the occlusionobstruction and to perfuse the arm collateral flow. The subclavian steal syndrome is a rare but important cause of syncope.

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 artery occlusion or stenosis proximal to the origin of the vertebral artery. Subclavian artery stenosis is an uncommon vascular disease showing a 4-fold left rather than right-sided predisposition. Symptoms of SSS include vertigo during arm exertion and hand or arm pain and numbness or weakness in the arm involved due to hypoperfusion.

The left vertebral artery spectral wave doppler is seen below the baseline as compared to both left CCA and right vertebral artery. Subclavian steal syndrome occurs secondary to a proximal stenosing lesion or occlusion in the subclavian artery. Features are characteristic of complete left subclavian steal syndrome Features are characteristic of complete left subclavian steal syndrome.

Subclavian steal syndrome SSS is a condition secondary to an occlusion in the proximal subclavian artery which leads to upper-extremity blood supply to be derived by reversal of flow within the ipsilateral VA. Blood is drawn from the collateral circulation which results in reversed blood flow in the ipsilateral vertebral artery. The term subclavian steal was coined by Fisher as the reversed retrograde ipsilateral vertebral blood flow was due to the stealing of blood from the posterior cerebral circulation by the subclavian artery.

Patients can present with limb claudication and or cerebral symptoms. Bilateral cervical bruits a difference in blood pressure 4550 mmHg between both arms as well as barely discernable radial ulnar and branchial arterial pulses on the right upper limb prompted color duplex which revealed bilateral internal carotid artery stenosis of 75 at each side retrograde flow in his right vertebral artery subclavian-vertebral steal and retrograde flow in his right carotid artery during the midsystolic phase of the cardiac cycle subclavian-carotid steal.
