Sixty consecutive patients with phlebographically verified deep venous thrombosis of the upper arm were studied for disorders of coagulation and fibrinolysis. No appreciable increase in abnormalities of the factor VIII complex, antithrombin III, or inhibitors of activators of fibrinolysis were found. A decreased fibrinolytic defence mechanism, evident either as a deficient release capacity of fibrinolytic activators from the vein during stasis or as decreased fibrinolytic activity in the vein wall as determined histochemically, was found in 26 out of 53 patients studied (49%). It is concluded that deep venous thrombosis of the upper arm is a multifactorial disease. An impaired fibrinolytic defence mechanism is one of the factors that may be of pathogenetic importance.
