Abstract

Objectives: In living-donor-liver transplantation (LDLT), microsurgical reconstruction of the hepatic artery is an essential but challenging issue. Especially using a living donor graft, the hepatic artery is short, the intimal damage may be severe, and the usable vessel grafts are limited compared with cadaveric donors. Thus, sometimes it is difficult to use a conventional twist reconstruction technique in which one needs to turn over the hepatic artery. Methods: To overcome these difficulties, we began to use a back wall support suture technique. From July 1991 to June 2007, we performed 110 LDLTs. In 87 cases, we used the conventional twist technique. In the most recent 23 cases, we used a back wall support suture technique. To put it briefly, we placed 2 sutures at the deepest, most difficult points in the artery for backside support. Each stitch was placed from the inner side of the arterial wall to the outer side with double needle sutures. The subsequent sutures were placed forward on either side adjacent to the previous suture. Results: The total ratio of hepatic artery thrombosis (HAT) was 8.2% (9/110). In the conventional twist technique group, HAT occurred in 8 cases (9.2%). In the new technique group, it occurred in only 1 case that had an intimal dissection in the recipient artery (4.3%). Thus there was no HAT associated with the arterial anastomosis in the new technique group. Conclusion: Our technique allows for safe intimal adaptation without turning over the artery. In conclusion, this back wall support suture technique may contribute to more satisfactory results.
