Proximal occlusions of the subclavian and innominate arteries may create a cerebrovascular insufficiency syndrome. The syndrome is generally characterized by neurologic symptoms of the vertebral-basilar arterial distribution. Blood is siphoned along the vertebral artery because of the low pressures distal to the occlusion. The clinical syndrome is best confirmed by a thoracic arch aortogram. Treatment is reserved for symptomatic patients. An extra-thoracic revascularization of the distal subclavian artery is the preferred operation.
锁骨下动脉和无名动脉近端闭塞可能会引发脑血管供血不足综合征。该综合征通常以椎基底动脉分布区的神经症状为特征。由于闭塞远端压力较低，血液会沿椎动脉被虹吸。胸部主动脉弓血管造影最有助于确诊该临床综合征。仅对有症状的患者进行治疗。首选手术是锁骨下动脉远端的胸外血管重建术。
