Fertility and pregnancy outcomes after transvaginal cervico-isthmic cerclage.

INTRODUCTION

Prematurity is the leading cause of neonatal morbidity and mortality. Cervical insufficiency seems to be the main risk factor. Treatment is cervical cerclage. In case of failure, a cervico-isthmic cerclage by Fernandez' technique, with the placement of a polypropylene sling by vaginal approach during the first trimester of pregnancy, has proven its effectiveness. The aim of our study is to report effectiveness of Fernandez' cervico-isthmic cerclage in subsequent pregnancies.

MATERIALS AND

METHODS

This retrospective study, was conducted from March 2002 to April 2014 in the gynecologic department of two teaching hospitals. The inclusion criterion was history of cervico-isthmic cerclage using Fernandez's technique during the previous pregnancy. This study received IRB approval number CEROG 2016-GYN-0302.

RESULTS

125 women underwent a definitive cervico-isthmic cerclage. The total percentage of neonatal survival after 14 weeks was 91% and the total percentage of neonatal survival after 24 weeks of gestation was 98.2%. Out of 114 women, 33 desired a second pregnancy. Out of which 29 had a spontaneous pregnancy. The percentage of total neonatal survival rate after 14 weeks was 92.86% and the percentage of total neonatal survival after 24 weeks was 96.3%. Out of the 29 women with a second pregnancy, 5 women achieved a third pregnancy. The five births occurred after 37 weeks of gestation with a percentage of total neonatal survival of 100%.

CONCLUSION

The cervico isthmic cerclage using the technique of Fernandez makes it possible to obtain subsequent pregnancies without further surgery with very satisfactory results regarding neonatal survival.
