[Effectiveness of cervical suture in the prophylaxis of premature deliveries (author's transl)].

Results of surgical treatment of cervical insufficiency according to McDonald's method in 150 pregnant women are discussed. The diagnosis was based upon anamnesis, examination of the vaginal segment of the uterus and the behaviour of cervix throughout the gestation period. The results depended upon the extent to which uterine cervix dilated before operation. Sutures were inserted in 150 pregnant women, and positive results were obtained in 119 cases (79%). In pregnant women with obstetric history of incompetence a prophylactic application of cervical sutures seems to be justified.
