Examinations of the blood flow in the vertebral arteries were carried out in 105 patients with circulatory disorders in the vertebrobasilary system. For this purpose the method of ultrasonic dopplerography with subsequent bilateral axillar cerebral angiography was used. The examinations were performed by the transcutaneous method in the author's modification. This made it possible to evaluate reliably the hemodynamics in the vertebral arteries in each patient using the asymmetry coefficient related to the linear speed of the blood flow in the vessels. It was found that in increase of the asymmetry coefficient by 50% or more was, as a rule, associated with an occluding process in one of the vertebral arteries. The agreement between the dopplerographic and the angiographic findings was observed in 80% of the cases of occlusions, and in 85,7% of the cases of vertebral artery stenoses. This makes it possible to recommend the ultrasonic dopplerography method for broad use in polyclinic conditions for examining patients with vertebrobasilar pathology, and for screening persons with an increased risk of cerebrovascular diseases.
对105例椎基底动脉系统循环障碍患者进行了椎动脉血流检查。为此，采用了超声多普勒检查法并随后进行双侧腋脑血管造影。检查采用作者改良的经皮方法进行。这使得能够利用与血管内血流线速度相关的不对称系数，可靠地评估每位患者椎动脉的血流动力学。结果发现，不对称系数增加50%或更多通常与一侧椎动脉的闭塞过程有关。在80%的闭塞病例和85.7%的椎动脉狭窄病例中，观察到多普勒检查结果与血管造影结果相符。这使得可以推荐超声多普勒检查法在门诊条件下广泛用于检查椎基底动脉病变患者，以及筛查脑血管疾病风险增加的人群。
