[DDAVP: alternative to replacement treatment in mild haemophilia A and von Willebrand-Jürgens syndrome (author's transl)].

1-Deamino-8-D-arginine vasopressin (DDAVP), a vasopressin analogue, increases factor VIII levels in plasma. A female carrier of haemophilia A with known bleeding diathesis and markedly reduced factor VIII activity was successfully treated with DDAVP during bilateral Caldwell-Luc's operation for chronic maxillary sinusitis. An estimated 5000 U factor VIII concentrate was calculated to have been saved. DDAVP is the first alternative to replacement therapy in the treatment of moderate and mold forms of haemophilia A and von Willebrand's disease.
