Introduction: Cervical cerclage has been advocated in cases of ‘cervical incompetence’. There is very little evidence on the
material to be used for cerclage. Here we have used nylon wool over semicircular needle for cervical cerclage.
Material and Methods: 30 patients were included in the study. After a written informed consent, the patient was then taken for
cervical cerclage suture application. The material used was dark colored nylon wool. The primary outcome was live birth rate of the
baby where as the secondary outcome parameters included period of gestation at delivery, mode of delivery, length of hospitalization
of the baby, NICU if required, requirement of another cerclage in subsequent pregnancies and the timing of removal of cerclage.
Results: Out of the 30 pregnancies 29 were singleton pregnancies and 1 was twin pregnancy. The mean gestational age was
16.3 weeks. The mean duration between the cerclage and delivery was 137.6 days. All children survived their hospital stay and were
discharged to home. 11 patients came for management of subsequent pregnancy. Close USG monitoring was done while deciding
for the cerclage.
Conclusion: The present study of patients who were applied McDonalds cervical cerclage suture using nylon wool sutures have
shown satisfactory prolongation of the period of gestation. All the newborns apart from 1 fetus, survived and were discharged to
home. The results are promising, and they show that nylon wool can be used for McDonald’s cerclage.
