锁骨下动脉窃血综合征(Subclavian steal syndrome,SSS)是指同侧椎动脉出现逆行血流后发生的一系列症状。本文对SSS的病理、生理学,临床症状,诊断及治疗综述如下。1解剖与病理、生理学SSS通常是由于锁骨下动脉闭塞或严重狭窄所致,导致锁骨下动脉病变远端动脉内压力降低。如果锁骨下动脉严重狭窄以及动脉病变侧上肢活动时,血管内血流压力下降引起 Subclavian steal syndrome (SSS) refers to a series of symptoms that occur after retrograde blood flow in the ipsilateral vertebral artery. This article on the SSS pathology, physiology, clinical symptoms, diagnosis and treatment are summarized below. 1 Anatomy and pathology, physiology SSS is usually due to occlusion of the subclavian artery or severe stenosis, resulting in decreased pressure in the distal artery of the subclavian artery. If severe subclavian artery stenosis and arterial disease side of the upper limb activity, decreased intravascular blood pressure caused
