In medicine subclavian steal syndrome also called subclavian steal phenomenon or subclavian steal steno-occlusive disease is a constellation of signs and symptoms that arise from retrograde flow of blood in the vertebral artery or the internal thoracic artery due to a proximal stenosis andor occlusion of the. A clinically significant reduction in blood supply to the BRAIN STEM and CEREBELLUM ie VERTEBROBASILAR INSUFFICIENCY resulting from reversal of blood flow through the VERTEBRAL ARTERY from occlusion or stenosis of the proximal subclavian or brachiocephalic artery.
