[Modifications induced on thrombin and plasmin activity by voluntary interruption of pregnancy].

Pregnancy is characterized by plasmatic variations of coagulative factors' concentration and by different haemostatic-fibrinolytic balance. At present it is possible, with EIA methods, to measure fibrinogen (FgDP) and fibrin (FbDP) degradation products with precision and accuracy, as direct indexes of fibrinolysis and the thrombin-antithrombin III complex (TAT) as indirect index of thrombophilia. We have considered the course of those indexes in 61 pregnant women within the tenth week of gestation, before and after voluntary pregnancy interruption (VPI) resulted without complications.
