VON WILLEBRAND DISEASE, Nathan Fox, MD (Digital)
Von Willebrand Disease (VWD) is a relatively common bleeding disease. With VWD, the Von Willebrand Factor (VWF) is deficient or defective. VWF is a blood glycoprotein involved in hemostasis. There are several subtypes of VWD, based on the exact pathophysiology of the condition (decreased levels of VWF vs. the several ways VWF can be defective).
