Menorrhagia from a haematologist's point of view. Part I: initial evaluation.
The evaluation of menorrhagia should no longer be solely the task of the gynaecologist. In women with ovulatory bleeding (regular cycles), the prevalence of von Willebrand disease (vWD) in about 15% of these, as well as disorders of platelet function and fibrinolysis causing menorrhagia, warrants an active role by the haematologist. Initial intake should include documentation of menorrhagia by the pictorial chart assessment of menstrual flow. Baseline characteristics of menstrual flow should also be documented, including the frequency of changing the sanitary pad on the heaviest day, use of more than one sanitary pad at a time, number of days lost from school/work and the impact of menses on various quality-of-life parameters. Menorrhagia since menarche, a past history of surgical- and/or dental-related bleeding and a past history of postpartum haemorrhage are items of the bleeding symptom audit that appear in part to predict vWD in women with menorrhagia. Epistaxis and easy bruising do not appear to be clearly discriminatory symptoms. Initial testing should include the complete blood cell count, prothrombin time, activated partial thromboplastin time, iron profile, serum creatinine, thyroid stimulating hormone level, factor VIII level, vWF antigen, ristocetin cofactor and platelet aggregation studies. Additional haemostatic studies may also include a factor XI level and euglobulin clot lysis time. This extensive medical evaluation should assure both the patient and the gynaecologist that the possibility of an underlying haemostatic disorder has been thoroughly investigated, to avoid the patient undergoing further costly procedures and surgical interventions if an underlying haemostatic disorder remains unrecognized.
