Abstract

Subclavian steal syndrome is a diagnosis that is thought to be relatively uncommon even though its occurrence is not well understood. Some individuals may experience crippling symptoms of arm ischemia and vertebral-basilar insufficiency due to subclavian steal, which is more frequent than the accompanying illness. Patients with uneven arm blood pressure or unilaterally faint pulses should be evaluated for subclavian steal. Although it is not always necessary to check the blood pressure and pulse on both sides, they become significant when these measurements differ and are accompanied by vertebral-basilar or arm ischemia symptoms. Although subclavian steal does not significantly increase the risk of stroke, it is nevertheless essential to recognize and treat asymmetric blood pressure and weak pulses as these may be signs of subclavian steal syndrome. This page thoroughly analyses the aetiology of subclavian steal syndrome, signs, symptoms, diagnosis, and available treatments.
