Retransplant of the Liver: 12-Year Experience of the Shiraz Organs Transplantation Center

Abstract

Objectives: Liver transplant is the most effective treatment modality for patients with end-stage liver disease, metabolic disorders, hepatic malignancy, and acute liver failure. When a graft fails after primary liver transplant, retransplant of the liver remains the only option. Here, we report the past 12-year experience of the Shiraz Transplant Center regarding liver retransplant.

Materials and methods: This is a retrospective cohort study of a 12-year period (2004-2015) of the Shiraz Center in Iran.

Results: Of the 3107 patients who had a liver transplant during the study period, 58 retransplants were performed (1.86%) in 57 patients. The leading cause of retransplant was primary nonfunction in 24 patients (41.4% of retransplant cases and 0.77% of all liver transplant cases). The second leading cause of retransplant was vascular complications in 25 patients (23 with hepatic artery thrombosis and 2 with portal vein thrombosis), accounting for 43.1% of retransplant cases and 0.80% of all liver transplant cases. In addition, 5 patients (8.6%) had retransplant for rejection, which accounted for 0.16% of all liver transplant cases. Four patients with retransplant (6.9%) had recurrence of primary disease, which accounted for 0.12% of all liver transplant cases. Most liver retransplants occurred early (≤ 30 days after primary transplant) at the Shiraz Transplant Center. Five-year survival rate after retransplant was 35%, and retransplant for hepatic artery thrombosis was more common in children.

Conclusions: Because most patients required retransplants in the early period after primary transplant, the decision for retransplant must be considered carefully with full multidisciplinary evaluation and only in skilled hands. Retransplant in subgroups of patients with little chance of a successful outcome should be avoided.
