本报告描述了两例在活体肝移植（LDLT）中出现罕见肝动脉并发症的获救病例。在这两种情况下，一段自体肠系膜下动脉（IMA）被成功地用作显微手术下血运重建的动脉移植物。第一个病例是肝动脉假性动脉瘤，引起大量消化道出血。将动脉瘤前和动脉瘤后的肝动脉分开，并插入受体IMA的动脉移植物进行重建。第二个病例是受体肝动脉内膜夹层。由于剥离延伸至肝总动脉根部，因此将自体IMA插入供体肝动脉和受体脾动脉近端残端之间。自体IMA动脉移植重建肝动脉是可行的。
This report describes two rescued cases with rare complications of the hepatic artery in living-donor liver transplantation (LDLT). In both cases a segment of the autologous inferior mesenteric artery (IMA) was successfully used as an arterial graft for re-vascularization under microsurgery. The first case was that of a pseudoaneurysm of the hepatic artery, which caused massive gastrointestinal bleeding. The hepatic arteries of the pre- and post-aneurysm were divided, and the arterial graft from the recipient's IMA was interposed for reconstruction. The second case was that of an intimal dissection of the recipient's hepatic artery. Because the dissection extended to the root of the common hepatic artery, the autologous IMA was interposed between the donor's hepatic artery and the proximal stump of the recipient's splenic artery. Reconstruction using the arterial graft of the autologous IMA is feasible for re-vascularization of the hepatic artery in liver transplantation.
