Method for Creation of the Aortotomy Site for Saphenous Vein Grafts

Saphenous vein coronary artery bypass grafting requires a proximal anastomosis of the vein to the aorta. A variety of techniques have been described to create the aortotomy. We have developed a four-sided knife (Xcision Scalpel; patent pending, Research Medical, Inc, Midvale, UT) that facilitates the creation of a more uniform circular aortotomy. The purpose of this communication is to describe the knife and the technique for its use.
