[Cervical incompetence: diagnosis, indications and cerclage outcome]

Cervical incompetence, a major cause of late abortions and preterm delivery is a diagnosis increasingly easy to establish.Strapping is deemed effective to prevent recurrence of such accidents midwifery.

To evaluate the relevance of the diagnosis of cervical incompetence, check the main indications of banding and study the outcome of rimmed pregnancies.

A retrospective study about 103 rimmed pregnancies collected in the service of Motherhood Hospital Mahmoud El Matri Ariana to the period of January 2001 until December 2008.

The diagnosis of cervical incompetence is suspected in a body of evidence linking ATCD of late abortions or premature births found in respectively 46.2% and 31.1% of our patients in our series, 16.98% are carriers of known uterine defects. 8.49% are classified as high risk front of 3-ATCD of late abortions or preterm delivery and were circled systematically. 2.83% are rimmed after confirmation the incompetent cervix by calibration of the cervix and 55.99% because of clinically short cervix. The strapping has reduced the rate of late abortion which decreased from 46.6% before strapping to 7.6% after. As for preterm delivery, it is reduced from 31.1% before strapping to 18.5% after. This difference is statistically significant. The average term of confinement in our series is 36SA six days. 68 cases were delivered at term. Among patients in whom we have accepted the vaginal delivery, 74.2% had spontaneous labor. One case of rupture of the anterior lip of the cervix was noted.

The indication of a cervical strapping needs a well established diagnosis involving data from history, clinical examination and possibly endo-vaginal ultrasound to confirm the high-risk of cervical incompetence. The strapping participates significantly to prolong the duration of pregnancy, to lower rates of early major premature and to improve the chance of viability and prognosis of fetuses without serious repercussions on the workflow.
