Why is the greater saphenous vein used for a bypass graft? |
|
Answer» becozz The valvotomized vein USED as a bypass graft functions more like a NORMAL CORONARY artery. The main ADVANTAGE of using the vein in a nonreversed position is that the proximal orifice in the AORTA can be made larger, thereby preventing fibrosis leading to obstruction at the aortic anastomosis |
