The authors studied hemodynamics in the vertebral arteries in 62 patients with the scalenus-anticus syndrome by means of radioconstrast angiography and ultrasonic angiography which produced a colour image of the vessels with calculation of the diameter and the linear and volume blood flow rate. The results of the study showed that in constriction of the subclavian artery to 60% of its diameter in the typical place, the volume blood flow rate in the vertebral arteries remained normal (184 +/- 6.9 ml/min) but reduced 1.5-2 times during the functional test. Adequate surgical correction restored normal hemodynamics, control ultrasonic angiography recorded increase of the volume blood flow rate in the vertebral values to normal values. Ultrasonic angiography provides authentic information on the character of affection of the subclavian artery in the scalenus-anticus syndrome and makes it possible to appraise the hemodynamic significance of affection of the vertebral arteries. Besides, the method allows objective evaluation of the efficacy of treatment and quantitative characteristics of hemodynamics.
作者通过放射性造影血管造影术和超声血管造影术对62例前斜角肌综合征患者的椎动脉血流动力学进行了研究，超声血管造影术可生成血管彩色图像，并计算血管直径、线性血流速度和容积血流速度。研究结果表明，在典型部位锁骨下动脉缩窄至其直径的60%时，椎动脉的容积血流速度保持正常（184±6.9毫升/分钟），但在功能测试期间降低了1.5至2倍。适当的手术矫正可恢复正常的血流动力学，对照超声血管造影显示椎动脉的容积血流速度增加至正常值。超声血管造影术可提供有关前斜角肌综合征中锁骨下动脉病变特征的可靠信息，并能够评估椎动脉病变对血流动力学的影响。此外，该方法还可对治疗效果进行客观评估，并对血流动力学进行定量分析。
