An aorto-coronary bypass grafting was performed in a 50 year-old man, a Jehovah's Witness, suffering from effort angina pectoris. Preoperatively, he was underwent PTCA for LAD occlusion, which failed.

Single aorto-coronary bypass grafting using IMA was performed under the extracorporeal circulation primed with Ringer's Lactate and albumin. Moderate hypothermia with core temperature of 31.5℃ was used, and minimal level of the hematocrit was 18% during the perfusion.

At the start of the operation, 800ml of blood were withdrawn from the jugular vein to the blood bag which connected to a peripheral venous line uninter-ruptedly. During the operation, the autologous blood was continuously transfused very slowly and most of the autologous blood was transfused after the termi-nation of extracorporeal circulation. The blood in the extracorporeal circuit was hemoconcentrated with ECUM (extracorporeal ultrafiltration method) from hematocrit level 22% to 35% and transfused.

The postoperative course was uneventful. At the time of discharge from hospital on the 42 nd post-operative day the hemoglobin level was 13. 1g/dl and hematocrit level was 42%.
