Objective: Assessment of graft patency following coronary artery bypass graft (CABG) by transit time flow meter technique.
目的：应用即时血流测量技术术中评估冠状动脉桥的通畅性。
EBCT flow study can provide quantitative data for evaluating coronary bypass graft patency to provide supplemental diagnosis of CABG 3 D reconstruction.
EBCT血流扫描，可以提供搭桥血管血流的定量数据，是评价血管三维重建定量诊断的补充；
More recently, the radial artery has been used as an aortocoronary graft, but little is known about the midterm and long-term patency of this conduit.
进一步的研究表明，桡动脉移植作为主动脉冠状动脉移植的一种，但对于这种移植通道的中期和长期效果知之很少。
The mortality rate at follow-up period was 7%, the total patency of graft was 86% and the patency of cavo-atrial graft was 93%.
随访期死亡率为7%。总人工血管通畅率为86 % ，而腔房人工血管的通畅率为93%。
Postoperative angiography and Doppler - Ultrasonic examination showed shunt patency in 90% of cases. Partial shunt thrombosis occurred in 2 cases in PTFE graft without supporting rings.
术后门脉系统彩色多谱勒超声及血管造影检查，向肝血流量无明显影响，分流道通畅率90%，普通ptfe者血栓形成2例。
