Summary

In Willebrand disease, there is currently no test available to identify non-invasively patients with a high risk of bleeding from angiodysplasias The study propose to use a sublingual capillary bed analysis by video-microscopy, a sensitive, reproducible and non-invasive technique, to assess whether sublingual capillary density is predictive of hemorrhagic risk for patients with von Willebrand disease.
