A new centrifugal pump (Sarns), originally designed for ventricular assist, was successfully used in two patients during repair of traumatic pseudoaneurysm of the descending thoracic aorta. The distal thoracic aorta was perfused without heparinization to avoid spinal cord and visceral ischemia, reduce afterload on the heart, and avoid clamp injury to the aorta. Distal mean aortic pressure was maintained above 50 mm Hg with a mean pump flow of 1.75 liter/minute. Proposed structural advantages of the Sarns centrifugal pump for perfusion of the distal thoracic aorta without heparin are resistance to thrombus formation, air embolus, and hemolysis.
一种最初设计用于心室辅助的新型离心泵（Sarns），在两名患者的胸降主动脉创伤性假性动脉瘤修复过程中成功使用。在未进行肝素化的情况下对胸主动脉远端进行灌注，以避免脊髓和内脏缺血、降低心脏后负荷并避免主动脉夹闭损伤。通过平均泵流量为1.75升/分钟，将主动脉远端平均压力维持在50毫米汞柱以上。Sarns离心泵用于在不使用肝素的情况下灌注胸主动脉远端的结构优势在于抗血栓形成、空气栓塞和溶血。
