INTRODUCTION: Recombinant activated factor VII (rFVIIa, NovoSeven, NovoNordiskA/S, Bagsvaerd, Denmark) has shown benefits in hemophilic patients and recently in transplant recipients. This study presents our experiences with rFVIIa in complicated liver transplant recipients.
METHODS: From May 2001 to August 2004, rFVIIa was administered to 7 patients undergoing liver transplantation. All treatments were made on emergency bases, except for 1 case with hemophilia A, who received prophylactic treatment. The drug was delivered when severe bleeding with coagulopathy persisted despite the usual treatment with blood products. The drug doses were 60-90 mug/kg; the results were evaluated clinically and analytically.
RESULTS: Seven patients undergoing liver transplantation were treated with FVIIa. Mean prothrombin times before and after treatment were 17.5 and 10.9 seconds, respectively, with a mean reduction of 7.2 seconds (P = .03). Mean thromboplastin times before and after treatment were 38.1 and 29.4 seconds, respectively, with a mean reduction of 8.7 seconds (P = .034). The average dose was 83.6 mug/kg, leading to decreased consumption of blood products (P < .01). In all cases, rFVIIa allowed sufficient hemostasis to carry on definitive treatment. There was no mortality in this series.
CONCLUSIONS: These results provide new evidence on the potential benefits of rFVIIa in liver transplantation, especially for rescue therapy in cases of severe bleeding.
