Abstract
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. Key-words: Ultrasonic Doppler technique - microvascular bypass - cerebral blood flow - cerebrovascular disorders
