Abstract

Glanzmann's thrombasthenia is an autosomal recessive inherited platelet function defect. Though, quantitatively normal, the aggregation ability of platelets is reduced leading to bleeding episodes requiring transfusion of platelet concentrates. We describe a case of 13-year-old girl who had recurrent episodes of epistaxis since birth and was managed with multiple platelet concentrate transfusions and recently admitted with severe epistaxis refractory to platelet transfusion. At this stage administration of recombinant activated factor VII (fVIIa) was considered, which was initially given at 90 microg/kg dose with little control of bleeding but subsequent second dose of 120 microg/kg was administered with excellent response and immediate control of bleeding.
