Abstract

In the classic subclavian steal syndrome, vertebrobasilar insufficiency is caused by reverse flow in the vertebral artery ipsilateral to a subclavian stenosis or occlusion. We present two patients with vertebrobasilar insufficiency and ipsilateral vertebral and subclavian occlusive disease. The postulated mechanism of vertebrobasilar insufficiency is reverse flow in collateral neck vessels. In both patients, symptoms were relieved by carotid subclavian bypass. Thus, vertebral occlusion ipsilateral to a subclavian stenosis does not preclude subclavian steal syndrome.

摘要

在典型的锁骨下动脉盗血综合征中，椎动脉供血不足是由锁骨下动脉狭窄或闭塞同侧椎动脉的逆流引起的。我们报告了两名患有椎动脉供血不足以及同侧椎动脉和锁骨下动脉闭塞性疾病的患者。推测椎动脉供血不足的机制是颈部侧支血管的逆流。在这两名患者中，颈动脉 - 锁骨下动脉搭桥术缓解了症状。因此，锁骨下动脉狭窄同侧的椎动脉闭塞并不排除锁骨下动脉盗血综合征。
