MISMATCH OF AORTOTOMY AND SAPHENOUS-VEIN GRAFT SIZE - A SIMPLE SOLUTION

Bleeding may occur at the proximal anastomosis of an aortocoronary byp ass graft due to the aortotomy being larger than the vein graft diamet er. This results in the wall of the vein being under tension, so that the anastomotic suture or further stitches may cut through. A partial thickness suture placed as a pursestring around the aortotomy may alle viate this situation, resulting in a smaller aortotomy with reduced ve in wall tension, improved hemostasis, and a more satisfactory anastomo tic vein contour.
