BACKGROUND: Epistaxis can have a variety of different local or systemic causes. It is the cardinal symptom of von Willebrand disease (VWD), the most frequent congenital bleeding disorder with a prevalence of approximately 1%. The usual routine coagulation screening tests (PT, APTT, platelet count) are not sufficient to diagnose VWD, factor XIII (FXIII)-deficiency or platelet dysfunction. METHOD: A prospective study was conducted implementing enhanced coagulation screening for bleeding disorders in a total of 100 inpatients admitted for epistaxis. RESULTS: A bleeding disorder was found in 13%. In eight patients VWD was diagnosed, in six patients FXIII-deficiency was found, and in one patient both. CONCLUSION: The prevalence of bleeding disorders in patients with epistaxis is higher than in the general population. Epistaxis can be the primary symptom of chronic inflammatory disease or malignant disease. A thorough anamnesis is necessary and in cases of doubt additional testing for underlying disorders is recommended.
