May 20, 2019 · 1 INTRODUCTION. Von Willebrand disease (VWD), the most frequent autosomal inherited bleeding disorder, is caused by quantitative or qualitative defects of von Willebrand factor (VWF), an adhesive protein that binds platelets to exposed sub-endothelium and carries factor VIII (FVIII) in circulation. 1, 2 As a consequence, in addition to the defect of VWF, also FVIII, the protein deficient in ...

Dec 6, 2019 · Surgical procedures represent a serious hemostatic challenge for patients with von Willebrand disease (VWD), and careful perioperative management is required to minimize bleeding risk. Risk stratification includes not only the nature of the surgery to be performed but the baseline plasma von Willebrand factor (VWF) levels, bleeding history, and ...

Jun 7, 2022 · Von Willebrand disease (VWD), first described by Dr. Erik von Willebrand, is the most common autosomal inherited bleeding disorder. It is caused by deficiency or dysfunction of von Willebrand factor (VWF), a plasma protein that mediates the initial adhesion of platelets at sites of vascular injury, and binds and stabilizes blood clotting factor ...

Apr 26, 2010 · von Willebrand disease is caused by either a quantitative or qualitative defect in von Willebrand factor (VWF). Patients may have extensive mucosal bleeding (because of platelet dysfunction) and prolonged bleeding after surgery (because of factor VIII deficiency). Up to 6 different subtypes of the disease have been described, and diagnosis is based on clinical suspicion and laboratory ...
Von Willebrand isease has da reported prevalence of 1.3% based on testing and survey of ethnically diverse 600 school-children, though the prevalence is lower when considering only those with symptomatic bleeding.1 The disease results from a deficiency in vWF, a glycoprotein that forms large multimers
