Surgical treatment of thoracic descending aortic aneurysm using pulsatile fanoro-femoral bypass

Abstract

It has been already recognized by many investigators that the pulsatile flow in extracorporeal circulation is very physiologic and effective than the non-pulsatile flow for open heart surgery Experiences with surgical treatment of descending aortic aneurysm with the aid of pulsatile femoro-femoral partial perfusion were reported. Function of the brain, kidney and peripheral circulation was safely protected and stable circulatory atate was maintained during aortic cross-clamping. The pulsatile flaw can get little derrangement for peripheral circulation, can hold in good condition the blood pressure, the peripheral vascular resistance and the ultrasonic flow curve findings during extracorporeal circulation and can get effectiveness for renal circulation. It can be concluded that extracorporeal circulation under pulsatile flow is more beneficial that those of roller pump during clinical extracorporeal circulation.
