Von Willebrand disease (VWD) is the most common hereditary blood-clotting disorder in humans. An acquired form can sometimes result from other medical conditions. [ 1 ] It arises from a deficiency in the quality or quantity of von Willebrand factor (VWF), a multimeric protein that is required for platelet adhesion .
The important role of depletion of von Willebrand factor in aortic stenosis was first proposed in 1992 by Warkentin et al. [7] They noted a known association between aortic stenosis (in addition to other cardiac diseases) and acquired von Willebrand's disease type IIA, [20] which is corrected by surgical replacement of the aortic valve. They ...

Hemophilia [7] Adverse reactions to clotting ...
Von Willebrand Disease is thankfully fairly rare, and many dogs will have the mildest form of the disease. If your dog has symptoms suggesting slow clotting or spontaneous bleeding, they will need ...
A right-sided acute deep vein thrombosis (to the left in the image). The leg is swollen and red due to venous outflow obstruction. The most common conditions associated with thrombophilia are deep vein thrombosis (DVT) and pulmonary embolism (PE), which are referred to collectively as venous thromboembolism (VTE).
Platelet storage pool deficiency is a family of clotting disorders characterized by deficient granules in platelets.Individuals with these disorders have too few or abnormally functioning alpha granules, delta granules, or both alpha and delta granules and are therefore unable to form effective clots, which leads to prolonged bleeding.
In this disorder, von Willebrand factor (vWF) is proteolysed due to high shear stress in the highly turbulent blood flow around the aortic valve. vWF is most active in vascular beds with high shear stress, including angiodysplasias, and deficiency of vWF increases the bleeding risk from such lesions.
It has been associated with Von Willebrand disease, Amegakaryocytic thrombocytopenia (low platelet count), prolonged activated partial thromboplastin time, combined coagulation defects. When present, these Noonan-syndrome accompanying disorders can be associated with a predisposition to bruise easily, or hemorrhage.
