Abstract
Of 49 patients with hemophilia A or B, who had not received replacement transfusions for at least 72 hours, ten were demonstrated to have a prolonged value for the bleeding time. None had evidence of von Willebrand's disease or prior aspirin ingestion, and only one was found to have an associated intrinsic platelet defect. It appears that the bleeding time, generally thought to be a measurement of platelet-subendothelium interaction, may also sometimes be prolonged in congenital coagulation disorders in which platelet function is normal.
