Results of liver retransplantations

Abstract

Aim. To present the results of repeated liver transplantations performed in a federal center. Materials and methods. The results of 268 orthotopic full-liver postmortem transplantations in 248 patients since 1998 were analyzed. Retransplantation was performed in 20 patients (8.1%) – 10 men and 10 women, 18-64 years old (median age 44.4 years). The median MELD score was 21 (19-24). Observations before 2006 were analyzed retrospectively. Early hepatic artery thrombosis and late biliary complications due to insufficient arterial blood supply to the graft indicated the retransplantation in the majority of patients. Results. The duration of preservation stages was comparable to the primary transplantation. Significant differences were found in the duration of the anhepatic period, the volume of hemotransfusion, the duration of the surgery, the rate of complications and the hospital mortality rate. Currently, 9 of the 20 patients (45%) are alive, with a follow-up period of 7-140 months. Graft function was satisfactory in most recipients. Hospital mortality accounted for 35%. Conclusion. Liver retransplantation is accompanied by considerable technical difficulties, as well as by an increase in surgery duration, volume of blood transfusion, time of stay in the intensive care unit, and incidence of postoperative complications. Infectious complications were the main cause of death. With successful retransplantation, long-term results and survival rates were comparable to those of primary transplantation.
