A 71-year-old male with a left ventricular aneurysm underwent aneurysmectomy. The patient could be weaned from cardiopulmonary bypass with high-doses of dopamine and dobutamine, followed by immediate left ventricular failure and systemic hypotension. IABP could not be applied to the patient because of the kinked bilateral common iliac arteries. In this condition a centrifugal pump system was connected between left atrium and ascending aorta. With a pump flow of 2 L/min the patient returned to an intensive care unit. After 48 hours of left heart bypass with minimal anticoagulation with systemic heparinization the device could be removed. The patient recovered without any complications, such as thromboembolism, renal failure or mediastinitis. He discharged in fair condition 3 months after the operation.
一名患有左心室动脉瘤的71岁男性接受了动脉瘤切除术。患者在大剂量多巴胺和多巴酚丁胺的支持下成功脱离体外循环，但随后立即出现左心室衰竭和全身性低血压。由于双侧髂总动脉扭曲，无法对该患者应用主动脉内球囊反搏（IABP）。在此情况下，在左心房和升主动脉之间连接了一个离心泵系统。以2升/分钟的泵流量，患者被送回重症监护病房。在进行了48小时的左心旁路转流并使用全身肝素化进行最小化抗凝后，该装置被移除。患者康复，未出现任何并发症，如血栓栓塞、肾衰竭或纵隔炎。术后3个月，他状况良好地出院了。
