Hemostatic technique for internal mammary artery anastomotic bleeding.

Abstract

When internal mammary artery is used for myocardial revascularization, a not uncommon occurrence is intraoperative bleeding from the internal mammary artery to coronary artery anastomosis. The conventional method of hemostasis of placing additional sutures across the suture line may produce anastomotic stenosis or may aggravate the bleeding by producing tears, especially as these additional sutures are placed on a beating heart. We describe a simple technique by which hemostasis can be achieved without the risk of anastomotic stenosis or aggravation of the bleeding, as it avoids placing sutures over the anastomotic suture line.
