Following an operative microvascular extraintracranial bypass, 50 patients were re-examined by the ultrasonic Doppler technique. The findings were compared with the results achieved by post-operative angiography. This examination of the patency of extraintracranial anastomoses with the ultrasonic Doppler technique can be conducted on an outpatient basis, is noninvasive and can be frequently repeated. It has a high degree of accuracy (96%). In addition, there were indications that, in certain areas, a gauge could be established for the function of the anastomosis by comparing the amplitude indices from the bypass and the afferent vessels.

在进行微血管颅外搭桥手术后，对50例患者采用超声多普勒技术进行了复查。将检查结果与术后血管造影的结果进行了比较。采用超声多普勒技术检查颅外吻合口通畅情况可在门诊进行，具有非侵入性且可频繁重复的特点。其准确率很高（96%）。此外，有迹象表明，在某些区域，通过比较搭桥血管和传入血管的振幅指数，可以建立吻合口功能的评估标准。关键词：超声多普勒技术 - 微血管搭桥 - 脑血流量 - 脑血管疾病
