[Treatment of thrombosis in pregnancy].

Treatment of venous thrombosis during pregnancy is not without risks. Therefore diagnosis has been made by phlebography. Streptokinase therapy is accompanied with bleedings and needs a precise indication. 4 women have been operated on by thrombectomy. Dicumaroles cause fetal demages and are not suitable for prophylaxis of recurrences. Heparin is the treatment of choice, partly by self injection. During parturition a short time change to low molecular dextran is recommended.
