Thrombosis (from Ancient Greek θρόμβωσις thrómbōsis "clotting”) is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system.When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss. The pathogenesis and prophylaxis of venous thrombosis of the lower extremities remains cloaked in mystery, despite (perhaps because of) the many articles in our overburdened literature, like that of Husni et al (214:1456-1462, 1970). application/pdf Ie 4.
