Effectiveness of delayed absorbable monofilament suture in emergency cerclage.

Abstract Objective To determine the sustained effects of emergency cerclage using slowly absorbable monofilament sutures, changes in cervical length after cerclage were evaluated in six cases. Materials and methods A delayed absorbable monofilament suture (1 PDS-Plus; Ethicon, Inc., Somerville, NJ, USA) has been used for emergency cerclage after 20 weeks of gestation at Juntendo University Hospital since January 2011. A retrospective chart review was conducted including all of the patients undergoing emergency cerclage between January 2011 and August 2013. The patients' characteristics, perinatal outcome, cervical length, and obstetric data were collected. Results Six cases were identified from our medical records. Their characteristics and perinatal outcomes are shown in Table 1. Of the six cases, four had an extremely short cervix, with an average cervical length of 7.85 ± 3.38 mm, and two had prolapsed membranes. Fig. 1 shows the cervical length and the time elapsed after cerclage. There were no cases with shortening of the cervical length below the levels at the cerclage. Conclusion This absorbable monofilament suture appears useful for emergency cerclage.
