    Abstract:
    OBJECTIVE: To evaluate the use of Arabin cerclage pessary in the management of cervical insufficiency. METHODS: The pregnancy outcome of 20 women carrying singleton pregnancy referred for suspected cervical insufficiency and chose Arabin cerclage pessary for treatment from 2009-2011 were reviewed. Pregnancy outcome were analysed according to presence of risk factors, amniotic fluid sludge, cervical length and gestation at pessary insertion. RESULTS: At presentation, mean cervical length was 1.17 cm (range 0-2.33 cm), mean gestation at pessary insertion and delivery was 20.6 (12.9-26.1) weeks and 32.1 (14.7-40.1) weeks, respectively, and mean prolongation of pregnancy was 11.5 (0.5-25.2) weeks. Overall, 5 (25%) had fetal loss between 14.7-23.1 weeks, while 3 (15%) and 12 (60%) delivered before and after 34 weeks gestation, respectively with no perinatal mortality. Compared with women with cervical length <1.5 cm, all those with cervical length ≥1.5 cm had pregnancy prolonged for ≥49 days (100 vs. 54% p = 0.032) and 86% delivered beyond 34 weeks (86 vs. 46% p = 0.085). CONCLUSIONS: Arabin cerclage pessary appears to be optimal for treating women at high risk of cervical insufficiency with a cervical length of 1.5-2.5 cm, while it is an acceptable option for high risk women with cervical length <1.5 cm.
