[Differential prevention of recurrence of thrombosis during pregnancy].

Pregnancy in patients with a history of thrombotic complications puts them at a great risk of thrombosis and obstetric complications (hypoxia, intrauterine hypotrophy, bleedings). Functional strain of the hemostasis system occurs at the onset of pregnancy in women with a history of thrombotic complications without clinical symptoms of thrombosis. The incidence of disseminated intravascular coagulation with activation of both pro-coagulation and platelet-mediated hemostasis is 33% and that with activation of only platelet-mediated hemostasis is 64%. Differential use of antithrombotic drugs prevents thrombosis recurrence in 98% of patients.
