When renal transplant recipients undergo aortic surgery, blood supply to the renal graft is interrupted while the aorta is clamped. Several innovative ways of using shunts have been described to preserve blood flow to the transplanted kidney during such surgery on the assumption that temporary warm ischemia of the renal transplant is poorly tolerated. We have performed aortic surgery in four renal transplant recipients without the use of any form of graft protection. One patient underwent urgent operation to treat an expanding aortic aneurysm and the other three had elective surgery for aortoiliac occlusive disease. Ischemic times ranged from 30 to 45 minutes. Two of the four patients had a temporary rise in serum creatinine levels. No patient required hemodialysis. We conclude that in selected renal transplant recipients, aortic surgery can be safely undertaken without graft protection.
当肾移植受者接受主动脉手术时，在主动脉钳夹期间肾移植的血液供应会中断。为了在这种手术期间保持移植肾的血流，人们描述了几种使用分流器的创新方法，前提是肾移植的短暂热缺血耐受性较差。我们对四名肾移植受者进行了主动脉手术，未使用任何形式的移植物保护。一名患者接受了紧急手术以治疗不断扩大的主动脉瘤，另外三名患者因主髂动脉闭塞性疾病接受了择期手术。缺血时间为30至45分钟。四名患者中有两名血清肌酐水平暂时升高。没有患者需要进行血液透析。我们得出结论，在选定的肾移植受者中，可以在不进行移植物保护的情况下安全地进行主动脉手术。
