Twenty-three coronary bypass graft patients were evaluated by a contrast-enhanced computed tomography (CT) technique to determine graft patency. Four to six 4.8-second sequenced scans with a 1-second interscan interval were obtained in each patient during the hand injection of 25-30 ml of contrast medium in a peripheral vein. Patency of grafts was determined by a characteristic contrast enhancement. The CT technique correlated with angiographic assessment of graft patency in 59 of 62 grafts (95%). We conclude that this relatively noninvasive technique shows promise as a method for determining coronary bypass graft patency.
对23例冠状动脉搭桥术患者采用对比增强计算机断层扫描（CT）技术评估移植血管通畅情况。在经外周静脉手动注射25 - 30 ml造影剂期间，对每位患者进行4至6次4.8秒的序列扫描，扫描间隔为1秒。通过特征性对比增强来确定移植血管的通畅情况。在62条移植血管中，CT技术与血管造影对移植血管通畅情况的评估结果在59条血管上具有相关性（95%）。我们得出结论，这种相对无创的技术有望成为一种确定冠状动脉搭桥移植血管通畅情况的方法。
