[Functional test of reactive hyperemia in the diagnosis of the vertebro-subclavian steal syndrome using ultrasonic dopplerography].

The authors used ultrasonic dopplerography (UD) and the reactive hyperemia test to diagnose the vertebral-subclavicular stealing syndrome (VSSS) with occlusion of the proximal segment of the subclavicular or innominate arteries. The sonographic and angiographic findings coincided in 92.3% of cases. It is concluded that UD is the method of choice in the evaluation of the efficiency of reconstructive surgery aimed at correcting the VSSS.
