Von Willebrand disease (vWD) is the most common bleeding disorder in humans. It is the result of an abnormality in the amount, structure, or function of von Willebrand factor (vWF), a glycoprotein important in maintaining normal hemostasis.. In children with vWD, the most frequent presentation is easy bruising and epistaxis. Other symptoms include hematomas, menorrhagia, and bleeding from minor wounds. Although intraarticular bleeding may occur, especially in certain subtypes, it is much more commonly seen with hemophilia. There are several subtypes of vWD based on the underlying defect in vWF, but, in general, they may be categorized as quantitative (types 1 and 3) or qualitative (all types 2). If vWD is suspected, consultation with a hematologist to establish the correct diagnosis and perioperative approach to hemostasis is essential. Avoidance of medications that interfere with coagulation, anticipation of intraoperative and postoperative bleeding, and an appropriate hemostatic treatment plan should be addressed.
