Clotting is a vital part of hemostasis, but when this process becomes dysregulated, it can lead to pathological clot formation. In harmful clot formation (pathological thrombosis) such as acute ischemic stroke, dysregulated clot formation blocks blood flow to the brain. Treatment focuses on restoring that flow, a process called recanalization.
vWF plays an essential role in clot formation and stabilization. It enables platelets to adhere to injured vessel walls and to each other, particularly in high-shear flow conditions. When endothelial injury and inflammation increase vWF activity at the vessel surface, platelet adhesion and aggregation intensify, driving pathological clot formation that can obstruct blood flow and damage tissue.
