Background: The rate of prematurity in twin pregnancies is higher than 50%.Due to
its multifactorial nature, different strategies are necessary to reduce the
incidence of premature birth or to increase the gestational age at birth of
pregnancies at risk. In this context, cervical pessary may be indicated in twin
pregnancies with short cervix.Methods: In thiscase series, we describe six twin pregnancies that were considered as
high-risk for preterm labor due to short cervix (CL < 30 mm)at
second trimester and multiple risk factors for prematurity. Several strategies
were associated for the goal of delaying gestational age at birth. The main
strategies were: removal of labor activities, treatment of infections, vaginal
micronized progesterone 400 mg/day and vaginal pessary insertion (Ingamed®？Brazil). Results: The gestational age of
insertion of the pessary ranged from 16 to 24 weeks. The gestational age of
birth ranged from 26 to 34 weeks. Three of the pregnancies were delivered due
to spontaneous onset of labor, and three were delivered due to medical reasons.
The mean length of pregnancy since pessary insertion to birth was 9 weeks
(range 2 to 17 weeks). All infants without severe fetal malformation
