Single center's experience of ABO-incompatible liver transplantation in 20 cases

Abstract

Objective To summarize 20 ABO-incompatible liver transplantation cases in our hospital and explore the treatment strategy. Methods From January 2009 to July 2011,20 cases donorrecipient ABO blood type not-identical liver transplantation was performed at our hospital. 16 cases were ABO-incompatible(ABO-Ⅰ) and 4 were ABO-compatible(ABO-C ).The median follow-up was (13.3 ± 9.2) months. Results Except preoperative MELD score,there were no significant difference in other perioperative data,the incidence of postoperative complications and the cumulative survival rate between ABO-C and ABO-Ⅰ group.There were 5 deaths in 20 cases,2 cases in ABO-C group and 3 cases in ABO-Ⅰ group,survival rate was 75％.The cause of death was perioperative multiple organ failure in 2 cases,liver cancer recurrence in 2 cases and cerebral hemorrhage in 1 case.There were 2 cases of acute rejection,3 cases of biliary complications and 3 cases of portal vein thrombosis developing postoperatively. Eleven patients had increased serum creatinine after operation,preoperative high creatinine existed in 6 cases and it maintained posttransplant high level for more than 7 days,the serum creatinine level in other 7 patients was back to normal level in 7 days. Conclusions A combination splenectomy before the portal vein reperfusion,the protocol of basiliximab,tacrolimus (TAC)/mycophenolate mofetil (MMF)/steroids immunosuppression treatment,postoperative peripheral vascular dilatation treatment by Alprostadil,help achieve favorable outcome in selected patients who underwent ABO-incompatible liver transplant.
