OBJECTIVE
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.
FINDINGS
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.
CONCLUSION
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.
目的
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。
研究结果
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。
结论
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。
