Case presentation: a patient with von Willebrand disease with menorrhagia

A 42-year-old woman who had two normal uncomplicated vaginal deliveries was seen for menorrhagia. Endocrine studies and ultrasonography had normal results. An elevated bleeding time and an activated partial thromboplastin time led to further hematologic testing. Final testing revealed abnormalities in the von Willebrand factor antigen, which led to a diagnosis of mild type I von Willebrand disease.
