A Significance of Emergency Cerclage in Cervical Incompetence with Advanced Cervical Dilatation / 대한산부인과학회잡지

ABSTRACT

OBJECTIVE: To investigate the clinical significance of emergency cerclage on prologation of pregnancy and perinatal outcome in mid-trimester cervical incompetence with advanced cervical dilatation. METHODS: We analyzed the pregnancy outcome retrospectively by the medical record review for 16 patients who had emergency cervical cerclage placed from March 1995 to June 2001. And these data were compared with those of 48 patients who had elective cervical cerclage placed during the same period. RESULTS: The mean gestational age of the patients at emergency cerclage was 22.0+/-2.3 weeks. The mean cervical dilatation was 2.9+/-1.2 cm and mean effacement was 55.3+/-4.7%. The mean prolongation of pregnancy after cerclage was 63.1+/-54.7 days (median 61, range 2-152) and the mean duration of antepartum hospitalization was 10.1+/-12.6 days (2-52). After cerclage, preterm premature rupture of the membranes occurred in 5 cases (31%), clinical chorioamnionitis in 3 cases (19%), and preterm labor in 5 cases (31%). The mean gestational age at delivery was 31.1+/-7.1 weeks. Perinatal survival rate was 85% (17/20), and neonatal survival rate was 94% (17/18). CONCLUSION: It seems that emergency cerclage contribute to maintenance of pregnancy and improve perinatal outcome of fetuses in cervical incompetence with advanced cervical dilatation.
