Abstract

OBJECTIVE: To compare the effectiveness of expectant management (EM), cervical cerclage (CC) and vaginal progesterone (VP) in decreasing the rate of spontaneous preterm birth in twin gestations with midtrimester cervical shortening.

STUDY DESIGN: This is a retrospective cohort study comparing pregnancy outcomes of twin gestations with midtrimester cervical shortening, defined as a cervical length (CL) on routine transvaginal ultrasound between 15 weeks 0 days and 24 weeks 6 days gestation of

RESULTS: Between January 2006 and July 2016, 64 pairs of twins with midtrimester cervical shortening were identified, 18 managed with EM (28.1%), 29 CC (45.3%), and 17 VP (26.6%), 52 of which had information regarding delivery outcomes. 90.4% of women delivered prematurely (<37 >weeks). Women in the CC group were diagnosed with cervical shortening at a significantly earlier mean gestational age (CC 20.6 ± 1.7 weeks versus EM 22.2 ± 2.9 weeks and VP 22.2 ± 2.0 weeks,

CONCLUSION: Twin pregnancies with midtrimester cervical shortening are at high risk for preterm delivery, and outcomes were similar regardless of management strategy. Large prospective trials are needed to evaluate the effect of different management strategies for cervical shortening in twins.
