ABSTRACT

Aims The various cerclage techniques with different clinical outcomes are developed for women with cervix incompetence. Among those methods, the McDonald’s cerclage is the most common and preferred technique. The objective of this study was to evaluate and compare the outcomes of the classic McDonald’s cerclage with the modified McDonald’s technique that was developed in Sarem women’s hospital.
Materials & Methods This analytical and historical cohort study was carried out on 105 pregnant women with documented cervical incompetence referred during one year to the Sarem women’s hospital. The patients were divided into two groups depending on the type of cerclage including modified McDonald (n=69) and classic McDonald (n=36) groups. Required information wa collected from the patients’ medical records as well as through telephone call. The data were analyzed using SPSS 22 and GraphPad Prism 6 softwares by T-student, Fisher’s exact and Chi-square tests.
Findings Modified McDonald’s cerclage was performed at higher gestational age compared to classic McDonald’s cerclage (p=0.0001). Despite on the higher preterm labor in the classic McDonald group, the term and preterm delivery rates were not significantly different between two groups (p=0.0601). There was a significant difference in the increase of cervical length following modified McDonald’s cerclage than classic McDonald’s cerclage (p=0.0257) and the patients in modified McDonald’s cerclage group showed a higher cervical length change after cerclage than the other group.
Conclusion Although there are no differences in preterm labor outcome between the two methods, the modified McDonald’s cerclage is a better treatment option because of the possibility to generate a longer cervical length compared to the classic McDonald’s method.
