The objective was to assess, with computed tomography (CT) angiography, quantitative morphological parameters of a composite coronary artery bypass grafting (CABG) strategy and to correlate these with graft dysfunction.
Forty patients [median postoperative time, 32 (14-51) months] underwent CT angiography. Graft patency was assessed, and specific quantitative morphological parameters of the graft were collected. Graft segments had an overall patency rate of 93% (78/84). Two specific morphological parameters were found to be associated with graft dysfunction.
A CT morphometric model can be used to identify quantitative 3D parameters associated with graft dysfunction. Such an approach could help in developing and improving CABG designs.
采用计算机断层扫描(CT)血管造影术评估复合冠状动脉旁路移植术(CABG)策略的定量形态学参数,并将这些参数与移植物功能障碍相关联。
40例患者[术后中位时间为32(14 - 51)个月]接受了CT血管造影。评估了移植物通畅情况,并收集了移植物的特定定量形态学参数。移植物节段的总体通畅率为93%(78/84)。发现两个特定的形态学参数与移植物功能障碍相关。
CT形态计量模型可用于识别与移植物功能障碍相关的定量三维参数。这种方法有助于开发和改进CABG设计。
