1960年Contorni从动脉造影发现一例左锁骨下动脉近心端狭窄的病例,因有侧支循环建立而无症状表现。1961年Reivich等发现两侧脑缺血病例有同样的动脉异常情况,称之为锁骨下动脉“盗血”综合症。至1971年已有384例报告。据动物实验,左锁骨下动脉受压使其中血流量减少10％,右侧推动脉血流量增加78％;右颈总动脉血流量增加22％;左颈总动脉血流量增加23％。由于侧支循环代偿而无症状出现,但当左上肢运动增剧而须大量血液自脑部流向左上肢时,可有轻度脑缺血症状,如代偿血管亦有粥样硬化等病变,脑缺血症状便很明显。锁骨下动脉“盗血”的病理变化是动脉粥样硬化伴有血栓形成,先天
In 1960, Contorni found a case of proximal stenosis of the left subclavian artery from arterial angiography, asymptomatic manifestations of collateral circulation. In 1961, Reivich et al. Found that the same bilateral arterial anomaly was found in bilateral cerebral ischemic cases, which was called the “steal syndrome” of the subclavian artery. By 1971, 384 cases had been reported. According to animal experiments, left subclavian artery compression in which the blood flow decreased by 10%, right to promote blood flow increased by 78%; right common carotid artery blood flow increased by 22%; left common carotid artery blood flow increased by 23%. Due to collateral circulation compensatory and asymptomatic, but when the left upper extremity movement increased and a large amount of blood flow from the brain to the left upper extremity, may have mild symptoms of cerebral ischemia, such as compensatory vascular disease also have atherosclerosis , The symptoms of cerebral ischemia are obvious. Subclavian artery “steal” pathological changes are atherosclerosis associated with thrombosis, congenital
