Abstract
Blood coagulation, clot retraction and fibrinolysis are generally studied under static conditions. These may bear little relevance to the physiological conditions in which they proceed under varying rates of flow and flow velocity. Similarly, the morphology of static (glass tube) clots differs greatly from the morphology of thrombi formed in veins and arteries. Glass tube clots show no visible platelet aggregates and are made up entirely of a random fibrin network with adherent or enmeshed red cells. A venous throm bus contains some platelet masses, whilst an arterial thrombus has large amorphous masses of platelet aggregates surrounded by leucocytes (1).
This study was supported by the National Heart Foundation of Australia.
