When renal failure complicates postoperative recovery in any operative procedure, the mortality is expected to double. To avoid this complication, a technique was devised to preserve renal perfusion during resection of a thoracoabdominal aneurysm. With systemic heparinization, an extravascular shunt is placed between the descending aorta and the visceral branches; any blood loss is recovered by autotransfusion. After completion of the operation and reversal of heparinization, the normal clotting mechanism is restored by terminal reinfusion of 2 units of autogenous blood that had been collected and stored before heparinization.
当肾衰竭使任何手术的术后恢复变得复杂时，死亡率预计会翻倍。为避免这种并发症，设计了一种在胸腹主动脉瘤切除术中保护肾灌注的技术。通过全身肝素化，在降主动脉和内脏分支之间放置一个血管外分流器；任何失血都通过自体输血回收。手术完成且肝素化逆转后，通过静脉回输2单位肝素化前采集并储存的自体血来恢复正常凝血机制。
