Technical considerations in saphenous vein bypass grafts to the right coronary artery.
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.
