We have employed Bin-Pump as the method of temporary bypass in the surgical treatment for the 30 patients with thoracic and thoracoabdominal aortic aneurysm at 8 institutes and evaluated its effectiveness in the same protocol. During aortic cross clamp, bypass flow of Bio-Pump averaged 1.91±0.45l/min and the mean pressure of the dorsalis pedis artery was adequately controlled around 73±22mmHg. Thus good hemodynamic could be maintained. Two cases were lost of DIC and subepidural bleeding.They were not related to the use of Bio-Pump. Hematological and biochemical findings revealed that the use of Bio-Pump did not directly affect to the major organs. It is necessary to require further examination about the employment of Bio-Pump in the case of profuse bleeding or the fall of body tempreture in long term bypass. But in conclusion, Bio-Pump has been found effective and reliable; good control of distal perfusion and with less use of heparin.
