Recombinant human factor VIIa in the management of amyloid-associated factor X deficiency
1Division of Hematology/Oncology, Department of Medicine, Northwestern University Medical School, Chicago, IL, USA.
Factor X deficiency is an important complication of amyloidosis. It is associated with severe bleeding that is difficult to control with plasma or prothrombin complex concentrates. Splenectomy ameliorates the factor X deficiency, but achieving satisfactory haemostasis for this operation is problematic. We report that a new clotting concentrate, recombinant factor VIIa, readily controls bleeding and makes splenectomy feasible.
