Abstract

The left subclavian artery was anastomosed with the left main coronary artery in 6 dogs, and the left internal mammary artery with the right coronary artery in 8 dogs, by the left thoracotomy. The procedures were performed using the extracorporeal circulation and hypothermia to 20°C, which made the occlusion of coronary blood flow possible for 50 min. without remarkable myocardial damage. The most difficulty in these operations was bleeding from the anastomosis, which had to be controlled by the careful suture techni-que.
