A New Supportive Method for Aortic Aneurysm Surgery: Centrifugal Left Heart Bypass Combined with an Oxygenator and a Heat Exchanger.

A new supportive method of centrifugal left heart bypass with oxygenation was performed in 25 patients and compared with standard left heart bypass in 45 patients. Femoro-femoral bypass was selected in another 6 patients because of the presence of a left atrial adhesion. Intraoperative complications related to standard left heart bypass, hypoxia, hypothermia, and ventricular fibrillation, were eliminated by using this method.
