Von Willebrand disease (VWD) is a disorder that makes it hard for your blood to clot. This happens because you don’t have enough of a clotting protein called von Willebrand factor (VWF).

Von Willebrand disease (VWD), the most common inherited bleeding disorder, is due to either a quantitative or qualitative abnormality of von Willebrand factor (VWF). VWF provides the critical link between platelets and exposed vascular subendothelium, and also binds and stabilises coagulation factor VIII. A full von Willebrand's investigation consist of the following assays: Clotting Screen (performed at GRH or CGH) Factor VIII assay (performed at GRH, CGH or Oxford Haemophilia Centre) Ristocetin Co-Factor (Ricof) Assay (performed at Oxford Haemophilia Centre) von Willebrand Factor - Collagen Binding Assay (performed at Oxford Haemophilia Centre) VWD, first described by Erik von Willebrand in a Scandinavian family, 1 is characterized by abnormal quantity or quality of von Willebrand factor (VWF), a large glycoprotein synthesized by megakaryocytes and endothelial cells and released into the circulation through a constitutive pathway and also upon stimulation. von Willebrands sjukdom klassificeras framför allt i tre olika typer efter defekt på vWF: Typ 1 (70 %) Kvantitativ defekt, vWF har normalt utseende men nivån i blodet är sänkt och nivån av Faktor VIII kan vara lätt sänkt.

Von Willebrand Disease is a genetic bleeding disorder where patients have a deficient or defective von Willebrand factor (VWF), a protein in the blood that is important for clot formation. While there is no cure for VWD, there are treatment options .

vWF is a blood-clotting protein and one of several components that work together and in sequence to stop bleeding by forming a blood clot. Normally, when a blood vessel is damaged, vWF first forms an adhesive bridge between activated cell fragments Von Willebrand disease (VWD) is a common inherited condition that can make you bleed more easily than normal. People with VWD have a low level of a substance called von Willebrand factor in their blood, or it does not work very well. Von Willebrand factor helps blood cells stick together (clot) when you bleed. Novel mutations previously overlooked in von Willebrand disease.

Von Willebrand qualified in medicine in 1896 from the INTRODUCTION. Von Willebrand factor (VWF) is a large multimeric glycoprotein that performs two critical functions in primary hemostasis: it acts as a bridging molecule at sites of vascular injury for normal platelet adhesion, and under high shear conditions, it promotes platelet aggregation. Von willebrand disease is the most common inherited bleeding disorder. Partial lack of VWF (von Willebrand factor) causes mild or moderate bleeding tendency.

Von Willebrand disease (VWD) is the most common inherited bleeding disorder, with a reported prevalence of approximately 1 in 1000 persons. 1 Quantitative defects include type 1 VWD, with partial deficiency of von Willebrand factor (VWF), and type 3 VWD, with virtually complete deficiency of VWF. Qualitative variants include defects in multimerization (type 2A), spontaneous platelet binding

The three types of hereditary VWD are VWD type 1, VWD type Von Willebrand disease (VWD) occurs with equal frequency among men and women, affecting up to 1% of the general population.

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). VWF provides the critical link between platelets and exposed vascular subendothelium, and also binds and stabilises coagulation factor VIII.
