Measurement of the proper length for saphenous vein bypass grafts to the right coronary artery can be complicated by the increase in cardiac volume that takes place when extracorporeal circulation is discontinued. Inadequate or excessive allowance for this increase can cause undue tension on the grafts or troublesome kinking. This report describes an improved method of orienting vein bypass grafts to the right coronary artery which eliminates problems of incorrect measurement.
测量用于右冠状动脉的大隐静脉搭桥移植物的合适长度可能会因体外循环停止时心脏容量增加而变得复杂。对这种增加的余量不足或过多都可能导致移植物承受不必要的张力或出现麻烦的扭结。本报告描述了一种改进的将静脉搭桥移植物与右冠状动脉对齐的方法，该方法消除了测量错误的问题。
