Emergency cervical circlage for cervical incompetence

Twelve patients had emergency cervical circlage for inevitable middle trimester abortion due to cervical incompetence. The mean gestation was 23 weeks (range 15-28 weeks). The median cervical dilatation was 3 cm. In three patients, the cervical dilatation was more than 5 cm. The median prolongation of pregnancy was 3.3 weeks (range 4 days to 10 weeks). Eight of the 14 babies survived. All babies that survived were more than 1000 g. Based on our experience, we advocate an active approach to inevitable middle trimester abortions due to cervical incompetence.
