subclavian steal syndrome

a vascular syndrome caused by an occlusion in the subclavian artery proximal to the origin of the vertebral artery. It results in a reversal of the normal blood pressure gradient in the vertebral artery and decreased blood flow distal to the occlusion. It is characterized by episodes of flaccid paralysis of the arm, pain in the mastoid and occipital areas, and a diminished or absent radial pulse on the involved side. Markedly different blood pressure measurements obtained from each arm are sometimes indicative of the condition.

subclavian steal syndrome

A phenomenon caused by a partial blockage of one of the main arteries that gives branches to the head and then to the arms. Use of the arm may divert blood from the head, leading to VERTIGO, headache, uncontrollable deviation of the eyes, double vision, nausea and vomiting. There is a serious risk of STROKE.
