背景：在活体肝移植（LDLT）中，没有肝中静脉（MHV）的右肝叶移植物会导致肝前段严重充血。然而，重建MHV或其支流的适应症和方法仍然存在争议。方法我们在此描述了两例成功使用受体再通的脐静脉作为间置移植物来引流右叶ldlt的主要MHV支流。结果两例右叶移植物术后功能良好，重建静脉支静脉均通畅。再通脐静脉的组织病理学特征显示内膜完整，中膜增厚。结论经受体再通的脐静脉是右肺小血管移植重建MHV血管的良好选择。
BACKGROUNDRight-lobe grafts without the middle hepatic vein (MHV) can cause severe congestion of the anterior segment in living-donor liver transplantation (LDLT). However, the indications and methods for reconstructing the MHV or its tributaries remain controversial.METHODSWe herein describe two cases of the successful use of the recipient’s recanalized umbilical vein as an interposition graft to drain the major MHV tributaries in right-lobe LDLTs.RESULTSAfter surgery, both right-lobe grafts are currently functioning well and all of the reconstructed venous tributaries have been confirmed to be patent by doppler ultrasonography. The histopathological features of the recanalized umbilical vein showed an intact intima with thickened media.CONCLUSIONSThe use of the recipient’s recanalized umbilical vein is a good option for reconstructing MHV tributaries in right-lobe LDLTs.
