Experiences of Amnioreduction and Emergency Cerclage for Advanced Cervical Incompetence

  • 1Department of Obstetrics and Gynecology, College of Medicine, Pochon CHA University, Seoul, Korea.


Cervical incompetence is one of the main contributors to repeated pregnancy loss and preterm delivery. Typically it results in progressive cervical dilatation, leading to a painless second or early third trimester abortion. Emergency cerclage can be used in the setting of advanced cervical incompetence, even when fetal membranes bulge through the dilated cervix. To facilitate the procedure, various techniques have been developed to replace the fetal membranes into the uterine cavity. We performed six successful cases of emergency cerclage combined with amnioreduction in advanced incompetent internal os of cervix (IIOC). Interval from emergency cerclage to delivery was 8.1 +/- 2.4 weeks (range 4-10 weeks) and we delivered viable fetuses in all but one. Hereby we report our experiences with a brief review of literature.
