Abstract

An international registry was established by the Subcommittee on von Willebrand Factor of the SSC/ISTH on the treatment of patients with types of von Willebrand disease (vWD) unresponsive to DDAVP infusion. Data was collected on 76 surgical events in 64 patients from 19 treatment centers. Thirty-three non-mucosal, 12 mucosal, 10 orthopedic and 21 dental procedures were reported. In the 76 surgical events, 14 cases prophylactically received cryoprecipitate while 62 received factor VIII (FVIII) concentrate. Surgical hemostasis was reported as satisfactory, good, or excellent in 75 of the 76 cases. Post-infusion bleeding times were measured in only three of 14 surgical events treated with cryoprecipitate. All three cases had a reduction but not correction of the bleeding time. The post-infusion bleeding time was measured in 27 of 62 cases in which FVIII concentrates were used. The bleeding time time was normalized in 15, reduced but not normalized in eight, and not changed from baseline in four. Data was also collected from 16 treatment centers on 50 serious bleeding events in 35 patients. These included 19 gastrointestinal, 15 other mucosal, four central nervous system, seven orthopedic, and five other mucosal, four central nervo...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
