[Antithrombin III level in normal pregnancy and patients with pregnancy-induced hypertension].

During pregnancy an increase of antithrombin III can be observed. In hypertensive pregnant women this increase may be smaller. This fact may be a sign of hypertension induced disseminated intravascular coagulation and important for prognosis and therapy of pregnancy-induced hypertension. We carried out estimations of antithrombin III by double determinations using radial immundiffusion. Antithrombin III levels were lower in patient with pregnancy-induced hypertension.
