冷冻保存的髂静脉移植物（IVG）通常用于重建右肝移植物中的肝中静脉（MHV）分支，但由于死者供体器官获取的发生率较低，我们机构的存储池经常被耗尽。为了克服 IVG 的短缺，我们开始使用冷冻保存的髂动脉移植物（IAG）。 2004年9月至10月，我院开展成人活体肝移植41例，其中MHV重建右叶肝移植29例。介入血管移植物为自体静脉 (n = 6)、IVG (n = 13) 和 IAG (n = 10)。在第一个月内，13 例中有 3 例（21%）使用了 IAG。在接下来的一个月中，它的使用频率更高（16 个月中的 7 个月 [44%]），因为冷冻保存的 JAG 的处理并不困难，而且结果良好。计算机断层扫描随访 3 个月后，6 例自体静脉病例中有 1 例（17%）出现流出道障碍，13 例 IVG 病例中有 2 例（15%）出现流出障碍，10 例 IAG 病例中有 1 例（10%）出现流出障碍。 IAG的两个月通畅率不低于IVG。总之，我们认为，在没有冷冻 IVG 的情况下，冷冻 JAG 可以用作右肝移植物 MHV 重建的中间血管移植物。
Cryopreserved iliac vein grafts (IVGs) have often been used for reconstruction of middle hepatic vein (MHV) branches in right liver grafts, but their storage pool has often been exhausted in our institution due to the low incidence of deceased donor organ procurement. To overcome this shortage of IVG, we started to use cryopreserved iliac artery graft (IAG). During September and October 2004, we carried out 41 cases of adult living donor liver transplantation, including 29 right lobe grafts with MHV reconstruction. Interposition vessel grafts were autologous vein (n = 6), IVG (n = 13), and IAG (n = 10). IAG was used in 3 (21%) of 13 cases during the first month. For the next month, it was more frequently used (7 [44%] of 16) because handling of cryopreserved JAG was not difficult and its outcome was favorable. On follow-up with computed tomography for 3 months, outflow disturbance occurred in 1 (17%) of 6 autologous vein cases, in 2 (15%) of 13 IVG cases, and in 1 (10%) of 10 IAG cases. Two-month patency rate of IAG was not lower than that of IVG. In conclusion, we feel that cryopreserved JAG can be used as an interposition vessel graft for MHV reconstruction of right liver graft when cryopreserved IVG is not available.
