Deficiencies of Coagulation-Inhibiting and Fibrinolytic Proteins in Outpatients with Deep-Vein Thrombosis

Abstract

The cause of acute venous thrombosis in most outpatients (91.7 percent) cannot be explained by abnormalities of coagulation-inhibiting and fibrinolytic proteins. The information obtained from the medical history concerning recurrent or familial venous thrombosis or the onset of the disease at a young age is not useful for the identification of patients with protein deficiencies.
