Outcome of emergency liver transplantation including mortality on the waiting list: A single-center experience

Patients with irreversible fulminant hepatic failure (FHF) as well as recipients with primary graft nonfunction (PNF) and early hepatic artery thrombosis (HAT) die unless they undergo emergent liver transplantation (OLT). Therefore, they have the highest priority in organ allocation systems. Herein we describe our initial experience with 18 emergency among 103 OLT procedures performed in 99 adults from February 2002 through February 2007. Their diagnoses were FHF (n = 16), PNF (n.= 1), and early HAT (n = 1). Ten subjects (56%) underwent emergency OLT after a mean 1.6 (range, 1 to 4) days after listing, whereas 8 (44%) patients died while awaiting a graft for a mean of 5.9 days (range, 2 to 17). All the transplants were performed according to the piggyback technique with routine preoperative use of intravenous recombinant factor VIIa (rVIIa) to control the coagulopathy, which resulted in significant (P < .0001), prompt correction of prothrombin time from a mean of 61 (range, 22 to 300) to 14 (range, 11 to 22) seconds at 15 minutes after drug administration. A mean of 4 (range, 0 to 14) units of RBC and 9 (range, 3 to 18) units of fresh frozen plasma were transfused during the procedure. Eight (80%) transplanted patients are alive in good condition with normal liver function at a mean of 18 (range, 4 to 36) months follow-up. Two patients died in the early postoperative period after massive aortic bleeding and biliary sepsis. In summary, only 56% of patients requiring emergency OLT received grafts achieving good medium and long-term survivals, which was significantly lower compared with Western European centers where this proportion reaches 90%. This outcome could be improved by international organ-sharing arrangements for emergency transplantation or living donation alternatives.
