Retransplantation of the liver: review of current literature for decision making and technical considerations.

Liver transplantation (LTx) is an established treatment modality for patients with end-stage liver disease, metabolic disorders, and patients with acute liver failure. When a graft fails after primary LTx, retransplantation of the liver (reLTx) is the only potential cure. ReLTx accounts for 7%-10% of all LTx in the United States. Early causes of graft failure for which reLTx may be indicated include primary graft nonfunction and vascular inflow thrombosis. ReLTx in such cases in the early postoperative period is usually straightforward as long as an appropriate secondary allograft is secured in a timely fashion. Late indications may include ischemic cholangiopathy, chronic rejection, and recurrence of the primary liver disease. ReLTx performed in the late period is often more complex and selection criteria are more stringent due to the persistent shortage of organs. The question of whether to retransplant patients with recurrent hepatitis C remains controversial, but these practices are likely to change as the epidemic progresses and new treatments evolve. We also present recent results with reLTx from Yale-New Haven Transplant Center and early results with the use of living donors for reLTx.

Favorable long-term outcome after liver-kidney transplant for recurrent hemolytic uremic syndrome associated with a factor H mutation.

A male child initially presented with atypical hemolytic uremic syndrome (HUS) at the age of 4 months and progressed within weeks to end stage renal disease (ESRD). At the age of 2 years he received a live-related kidney transplant from his mother, which, despite initial good function, was lost to recurrent disease after 2 weeks. Complement factor H analysis showed low serum levels and the presence of two mutations on different alleles (c.2918G > A, Cys973Tyr and c.3590T > C, Val1197Ala). His survival on dialysis was at risk because of access failure and recurrent bacteremic episodes. Therefore, at the age of 5 years he received a combined liver-kidney transplant with pre-operative plasma exchange. Initial function of both grafts was excellent and this has been maintained for over 2 years. This report suggests that despite setbacks in previous experience, combined liver-kidney transplantation offers the prospect of a favorable long-term outcome for patients with HUS associated with complement factor H mutations.
