Abstract:
Congenital factor VII (FVII) deficiency is a rare, autosomal recessive bleeding disorder with a spectrum of phenotypes ranging from asymptomatic to life-threatening intra-cranial hemorrhage (ICH). Orthotopic liver transplantation has been described for definitive treatment in a few patients with severe manifestations. We report a patient with congenital FVII deficiency and recurrent ICH, despite twice-weekly prophylaxis with recombinant activated FVII. At 17 months of age, he underwent an orthotopic liver transplant. He is now 1-year post-transplant, on maintenance immunosuppression with no hemorrhage or other complications.
