Prevention of spontaneous abortion by cervical suture of the malformed uterus

In a group of 82 women with congenital or acquired uterine malformation (such as intrauterine adhesions or uterus myomatosus), cerclage was successfully performed according to the McDonald method. The percentage of term deliveries increased from 29.8% to 69.2% and the percentage of spontaneous abortions decreased from 67.9% to 6.6%. Cerclage should be performed in all cases of uterine malformation, even if the patient previously suffered only one spontaneous abortion, as this is the best way to end the pregnancy with a viable fetus.
