Saphenous vein coronary artery bypass grafting requires a proximal ana
stomosis of the vein to the aorta. A variety of techniques have been d
escribed 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. T
he purpose of this communication is to describe the knife and the tech
nique for its use. (C) 1998 by The Society of Thoracic Surgeons.
