Subclavian artery steal syndrome

Subclavian steal syndrome refers to the partial or complete occlusive damage to the subcardiac artery or the head and arm trunk near the heart at the beginning of the vertebral artery. ) Causes retrograde blood flow in the affected vertebral artery and enters the telecentric segment of the inferior subclavian artery, leading to ischemic attacks of the vertebral-basal artery and ischemic symptoms of the affected upper limb. Angiography confirmed stenotic lesions in the proximal heart segment of the subclavian artery and retrograde blood flow in the lateral vertebral artery, first reported by Contomi in 1960, but the patient was neurologically free. Reivich further reported angiographic data and the symptoms of insufficient blood supply to the vertebral-basal artery in 1961, and performed animal (dog) experiments to confirm this phenomenon, and pointed out that this was a new vascular syndrome and named ldquo; Subclavian artery steal syndrome rdquo ;. This syndrome can also be seen in the disease of the head and arm trunk, because retrograde blood also enters the subclavian artery, so it can also be called ldquo; subclavian artery steal blood syndrome rdquo;
