In a preliminary evaluation of the use of dynamic computed tomography (CT) for the detection of patent aortocoronary bypass grafts, 30 patients were scanned either during the early postoperative period or after graft patency was determined by angiography. To visualize the proximal grafts, CT scans were taken through the aortic root following an intravenous bolus injection of contrast medium. Patent bypass grafts to the left anterior descending and right coronary arteries were demonstrated in 77.5%, while posterior grafts to the circumflex and obtuse marginal coronary arteries were detected in 40%. With its potential for extracting dynamic events, CT scanning provides a new, noninvasive modality for the diagnosis of patent bypass grafts, which heretofore have only been visualized by selective angiography.
在一项关于使用动态计算机断层扫描（CT）检测主动脉冠状动脉搭桥移植血管通畅情况的初步评估中，对30例患者在术后早期或在通过血管造影确定移植血管通畅后进行了扫描。为了观察近端移植血管，在静脉推注造影剂后通过主动脉根部进行CT扫描。左前降支和右冠状动脉的搭桥移植血管通畅情况在77.5%的患者中得以显示，而回旋支和钝缘支冠状动脉的后侧移植血管在40%的患者中被检测到。由于CT扫描具有捕捉动态事件的潜力，它为诊断搭桥移植血管通畅情况提供了一种新的非侵入性方法，而在此之前，只有通过选择性血管造影才能观察到移植血管的情况。
