Ultrasonic Doppler studies were made pre- and postoperatively in 22 patients undergoing STA-MCA anastomosis. A quantitative evaluation of the bypass was attempted by determining the STA blood flow velocity and pattern. The STA velocity on the Doppler sonogram was compared with the degree of intracranial vascular filling via anastomotic channels and the STA diameter on angiogram. The STA velocity was increased and the blood flow pattern of STA altered from an external carotid pattern to an internal carotid pattern in a patent bypass. The results were in good agreement with angiographic findings. The are of intracranial vascular filling via a vewly formed bypass on angiogram was proportional to the increase in STA velocity. As the STA diameter enlarged, the STA velocity increased progressively. It is suggested the Doppler flowmetry is reliable as a semi-quantitative means of evaluationg the STA-MCA anastomosis.
对22例行颞浅动脉-大脑中动脉吻合术的患者在术前和术后进行了超声多普勒研究。通过测定颞浅动脉血流速度和血流模式，尝试对搭桥术进行定量评估。将多普勒超声图上的颞浅动脉速度与通过吻合通道的颅内血管充盈程度以及血管造影上的颞浅动脉直径进行比较。在通畅的搭桥术中，颞浅动脉速度增加，颞浅动脉的血流模式从颈外动脉模式转变为颈内动脉模式。结果与血管造影结果高度一致。血管造影上通过新形成的搭桥术实现的颅内血管充盈面积与颞浅动脉速度的增加成正比。随着颞浅动脉直径增大，颞浅动脉速度逐渐增加。提示多普勒血流测定法作为评估颞浅动脉-大脑中动脉吻合术的半定量方法是可靠的。
