Platelets are cells that circulate in the bloodstream and help blood clot. The blood usually contains about 140,000 to 440,000 platelets per microliter (140 to 440 × 109 per liter). When the platelet count falls below about 50,000 platelets per microliter of blood (50 × 109 per liter), bleeding can occur even after relatively minor injury.
Symptoms and Signs of Von Willebrand Disease Bleeding manifestations in the most common type I von Willebrand disease (VWD) include bruising, mucosal bleeding, bleeding from small skin cuts that may stop and start over hours, increased menstrual bleeding, and sometimes bleeding after surgical procedures (eg, tooth extraction, tonsillectomy).

Nov 29, 2018 · Definition. Von Willebrand disease (VWD), the most common inherited bleeding disorder, is due to either a quantitative or qualitative abnormality of von Willebrand factor (VWF).
