ABO-incompatible orthotopic liver allografting in urgent indications.
The influence of ABO-compatibility was reviewed in 70 emergency orthotopic hepatic transplantations (OHT) performed at our institution in 60 highly urgent recipients between February 1984 and March 1989. Thirty-eight were ABO-identical (Id); 16, compatible (Comp), and 16, incompatible (Inc) transplants, respectively. The three groups did not differ statistically with respect to the indications, the adult/child ratio and the proportions of first OHT and retransplantations. Graft survival rates of ABO-Id, ABO-Comp and ABO-Inc OHT at one year were 47, 38 and 19 per cent, respectively (p less than 0.02). Incidences of perioperative mortality, arterial thrombosis and irreversible rejection were slightly (although not significantly) higher in the ABO-Inc group. Retransplantation rates were 19, 7 and 36 per cent in the ABO-Id, Comp and Inc groups, respectively. Patient survival rates at one year were 59 per cent for the ABO-Id group versus 43 per cent for both ABO-Comp and Inc combinations (NS). The results of this series of highly urgent OHT confirm that graft survival is lower with ABO-Inc livers; their use should be strictly considered as a short term life-saving procedure. Improvement of patient survival after a first urgent ABO-Inc OHT may require an aggressive policy of retransplantation.
