摘要
To expand the donor pool, split-liver transplantation has been implemented in recent years. In the classic technique, the arterial axis with the artery for segment 4 (S4) coming from the left hepatic artery (HA) is included with the right graft. To give a surgical advantage to pediatric recipients in our center, the left HA, the common HA, and the celiac trunk are generally retained with the left liver. Thus the artery for S4 is sacrificed. We compared the outcomes of S4 in 290 whole grafts (WG; group A) with 28 right in situ split-liver grafts (SSLG; group B), which were transplanted over the past 10 years (January 1999 December 2009). The rates of major biliary and of hemorrhagic complications were similar. In most of cases (16/24, 66%) S4, on computerized tomographic scan appeared to show signs of hypoperfusion, sometimes with a peripheral aspect of hyperperfusion in the arterial phase. Si showed signs of hypoperfusion in only 2 cases. A biliary collection near the resection line present in 8 cases was treated in 6 of them with percutaneous drainage and in 2 with laparotomy. These complications did not influence graft or patient survival. Graft survivals at 1, 5, and 10 years for WG and SSLG were not different among the groups: 85%, 74%, and 66% vs 89%, 79%, and 63%, respectively (P = .8). Although our technique cannot be considered to be anatomically correct, the ischemia of S4 did not influence the outcome. The rate of retransplantations for hepatic artery thrombosis was 17.9% in RSSG and 3.4% in WG (P = .001), which was probably due at least in part to the insertion of interposition grafts.
