cervical incompetence

Structural inability of the cervical os to remain closed and support a growing fetus. This problem has commonly been associated with recurrent spontaneous second-trimester abortions. A higher incidence of this structural abnormality is noted after cervical trauma, e.g., previous vaginal or cesarean births, cervical laceration, conization of the cervix. It also has been reported among daughters whose mothers were treated with diethylstilbestrol (DES) during their pregnancies. Traditionally, cerclage has been used for treatment even though controlled trials of its effectiveness have not been uniformly successful.

cervical incompetence

The inability of the inner opening of the neck of the womb to remain properly closed. This is a cause of repeated, painless, spontaneous abortions around the fourth or fifth month of pregnancy and affects about one pregnancy in 100. This can be prevented with a temporary encircling stitch (a Shirodkar suture), but the difficulty is to know which women are likely to be affected. Women with a history of mid-term miscarriage are obvious candidates for cerclage. The procedure can be done as an emergency if threatened miscarriage is detected in time.

It is important to mention that African-American women are more at risk in both aspects of premature births and cervical incompetence than their Caucasian counterparts.
Forty three of them, constituting 0.17%, were complicated by cervical incompetence for which cervical cerclage was performed.
Older women seeking to have a child not only are more likely to have had in vitro fertilization and other fertility treatments, they also are more likely to have had a loop electrosurgical excision procedure (LEEP), cone biopsy, or other procedure that has been associated with cervical incompetence. Many of these women are possible candidates for interval cerclage.
It is associated with various obstetric complications such as spontaneous abortion, preterm labour, cervical incompetence, mal-presentations and obstructed labour.
Patients were excluded if they had recurrent miscarriages, cervical incompetence, uterine anomalies, incomplete, missed or septic miscarriage and all patients in whom Dydrogesterone was contraindicated.
Common causes of incomplete procedures are the presence of a stenotic cervix or severe cervical angulation preventing insertion of the transcervical catheter, cervical incompetence or a very patulous cervix causing backflow of the saline solution into the vagina, large intrauterine fibroids and adhesions impeding distension of the uterine cavity, pelvic pain and vagal symptoms (9,13,15).
ACOG recommends a noninvasive approach because of the potential risk of cervical incompetence after surgical excision.
Nevertheless, since cervical incompetence is responsible for up to 15% of habitual immature deliveries of between 16 and 28 weeks' gestation, emergency cerclage will continue despite its associated risks.
It can result in obstetric complications such as spontaneous abortion, preterm labour, cervical incompetence and malpresentations.
