Maladie de Willebrand

Abstract Von Willebrand disease Von Willebrand disease is the most frequent congenital bleeding tendency (1%). The moderate form is the most common (around 80%). It must consistently be investigated prior to any surgery because of a real risk of bleeding during or after the procedure. Once the diagnosis is made, the indication of DDAVP has to be examined in order to make the best therapeutic choice in case of surgery or severe bleeding.
