The current organ shortage has made utilization of organs from less-than-ideal donors more common. Although several transplant centers use kidneys from non-heart-beating donors (NHBDs), there has been reluctance to extend the use of these donors to extrarenal organs. Of the 130 donors referred to our organ procurement organization between January 1993 and May 1994, 16 (12.3%) were NHBDs. Organ retrieval from 10 of these resulted in extrarenal donation, 5 resulted in renal donation only, and 1 resulted in no retrieval as a result of prolonged warm ischemia (> 2 hr). A total of 39 organs were transplanted from these NHBDs. A rapid en bloc retrieval technique was used for extrarenal NHBDs. The mean warm ischemic time was 15.4 min; preservation times were similar for both NHBDs and heart-beating donors. After liver transplantation (n = 5), one episode of primary nonfunction that was technical in origin required retransplantation. Following simultaneous pancreas-kidney transplantation (n = 6), all patients were insulin independent and free of graft pancreatitis; one patient required hemodialysis (16.7%). After isolated renal transplantation (n = 21), 3 patients (14.3%) required hemodialysis. Three of 4 liver recipients are alive after a mean follow-up period of 12.7 months; all simultaneous pancreas-kidney and renal transplant recipients are alive after a mean follow-up period of 8.4 and 8.3 months, respectively. Three liver allografts, 5 pancreas and kidney allografts, and 19 renal allografts are functioning. The lung allograft was lost to rejection 81 days after transplantation; however, the recipient is alive 3 months after retransplantation. Our results demonstrate that in controlled situations, extrarenal organs can be utilized from NHBDs and can be expected to function similarly to organs retrieved from heart-beating donors. We increased the number of transplanted organs by 8.6% using NHBDs for both renal and extrarenal donation. Continued application of these techniques will likely further increase the number of organs retrieved for transplantation.
当前的器官短缺使得利用不太理想的供体器官变得更为常见。尽管有几家移植中心使用非心脏跳动供体(NHBD)的肾脏,但人们一直不愿将这些供体的使用扩展到肾外器官。在1993年1月至1994年5月间转介到我们器官获取组织的130名供体中,有16名(12.3%)是非心脏跳动供体。从其中10名供体获取器官导致了肾外捐赠,5名仅导致了肾脏捐赠,1名由于长时间热缺血(>2小时)而未获取到器官。这些非心脏跳动供体共移植了39个器官。对于肾外非心脏跳动供体采用了快速整块获取技术。平均热缺血时间为15.4分钟;非心脏跳动供体和心脏跳动供体的保存时间相似。肝移植(n = 5)后,1例原发性无功能事件源于技术问题,需要再次移植。在胰肾联合移植(n = 6)后,所有患者均无需胰岛素且无移植胰腺胰腺炎;1例患者需要血液透析(16.7%)。在单纯肾移植(n = 21)后,3例患者(14.3%)需要血液透析。4例肝移植受者中有3例在平均随访12.7个月后存活;所有胰肾联合移植和肾移植受者在平均随访8.4个月和8.3个月后均存活。3个肝移植、5个胰肾联合移植和19个肾移植功能良好。肺移植在移植81天后因排斥反应失败;然而,受者在再次移植3个月后存活。我们的结果表明,在可控情况下,肾外器官可利用非心脏跳动供体获取,并且预期其功能与从心脏跳动供体获取的器官相似。通过使用非心脏跳动供体进行肾脏和肾外捐赠,我们使移植器官数量增加了8.6%。继续应用这些技术可能会进一步增加获取用于移植的器官数量。
