[An inherited hemostatic disorder as the cause of menorrhagia].

Two women aged 39 and 30 years were investigated for possible coagulation disorders because of menorrhagia, anaemia and postoperative haemorrhages. These investigations revealed that they had type 1 Von Willebrand's disease. During the treatment with desmopressin, factor VIII and Von Willebrand factor (VWF) activity normalised. About one third of the patients referred to a gynaecologist for menorrhagia have an inherited bleeding disorder, of which type 1 Von Willebrand's disease is the most prevalent. Once a gynaecological cause of the menorrhagia has been excluded, or in the case of an increased risk on the basis of the medical history, a limited haemostatic investigation can establish or exclude an inherited coagulation disorder. For women with a coagulation disorder the menorrhagia can be treated. Surgical interventions can be carried out safely following treatment with desmopressin or factor VIII/VWF concentrates.
