Frontiers Color Doppler Ultrasonography For The Evaluation Of Terminology. subclavian steal phenomenon refers to steno occlusive disease of the proximal subclavian artery with retrograde flow in the ipsilateral vertebral artery. subclavian steal syndrome is the same as subclavian steal phenomenon with the addition of cerebral ischemic symptoms. The term "subclavian steal" refers to a phenomenon of flow reversal in the vertebral artery ( figure 1) ipsilateral to a hemodynamically significant stenosis or occlusion of the prevertebral subclavian artery (subclavian, innominate) [ 1 3 ]. this represents an appropriate physiologic response to proximal arterial disease.

[1] subclavian steal is asymptomatic in most patients and does not warrant invasive evaluation or treatment. it can manifest in. Different variants of doppler waveforms in the normal and affected vertebral artery. occult subclavian steal corresponds to the milder form of hemodynamically significant subclavian artery stenosis, partial subclavian steal corresponds to the moderate form, and complete steal is observed in severe cases. Continuing education activity. subclavian artery stenosis is a form of peripheral arterial disease (pad). it may present with transient episodes of vertigo and circulatory symptoms involving the arms and hands. physical examination may demonstrate a weak pulse in one upper extremity and a systolic blood pressure difference of more than 10. A subclavian steal syndrome may occur when a significant stenosis in the subclavian artery compromises distal perfusion to the ima, vertebral artery, or axillary artery. as the degree of subclavian stenosis progresses, the pressure distal to the stenosis will eventually fall below the pressure transmitted by the contralateral (noncompromised.

Subclavian steal syndrome is defined as the reversal of blood flow due to significant stenosis of proximal subclavian artery. this syndrome was first described in 1960 by contorni . the patient can be symptomatic or asymptomatic depending on the degree of stenosis. Subclavian steal syndrome (sss), also known as subclavian vertebral artery steal syndrome, is a type of peripheral artery disease in which reduction or absence of flow in the proximal subclavian artery reverses the normal direction of blood flow in the vertebral artery.
