A retrospective study was conducted to evaluate the effect of Arabin cervical pessary in twin pregnancies with cervical length (CL) <25 mm between 21 and 31 weeks. Forty patients receiving pessary were matched with 40 controls without pessary. They were matched for gestational age (GA) at admission and CL. GA at delivery, delivery before 36, 34 and 32 weeks, latency between detection of short cervix and delivery, and duration of hospital admission were compared between groups. Women with the pessary delivered at higher GA compared to controls (35 vs. 33 weeks, p = 0.02). Cervical pessary significantly reduced the incidence of delivery <36 and < 34 weeks (p < 0.05), but not before 32 weeks. Interval between detection of short cervix and delivery was longer in the pessary group and duration of hospital admission was shorter (p = 0.03) compared to women without pessary.
