Of 41 saphenous vein aorta-coronary bypass grafts from 21 patients, abnormal graft tension was judged to be present at necropsy in 6 grafts (15 per cent) from 5 patients (24 per cent). Five (33 per cent) of 15 grafts placed to the right coronary system and one (3 per cent) of 26 grafts to the left coronary system were under excess tension. The abnormal tension appeared to result from the insertion of grafts too short to accommodate normal or abnormal distention of the right atrium and ventricle (graft to distal right coronary or posterior descending coronary artery) or of the pulmonary trunk (graft to left coronary system) after discontinuation of cardiopulmonary bypass or development of acute congestive cardiac failure.
在来自21名患者的41条大隐静脉主动脉-冠状动脉搭桥移植血管中，尸检判定6条移植血管（15%）存在异常的移植血管张力，这6条移植血管来自5名患者（24%）。置于右冠状动脉系统的15条移植血管中有5条（33%）以及置于左冠状动脉系统的26条移植血管中有1条（3%）处于张力过大状态。异常张力似乎是由于在体外循环停止后或急性充血性心力衰竭发生时，移植血管插入过短，无法适应右心房和右心室（移植至右冠状动脉远端或后降支冠状动脉）或肺动脉干（移植至左冠状动脉系统）的正常或异常扩张。
