PURPOSE: To evaluate the outcomes of cervical cerclage (CC) in twin pregnancies.
METHODS: Retrospective analysis of twin pregnancies undergoing CC between January 2001 and December 2009 at our Institution. CC was offered in case of a cervical length measurement ≤ 20 mm (ultrasound-indicated CC) or in case of cervical dilatation with membranes at or beyond the external cervical os (physical examination-indicated CC). Cervicovaginal and rectal swabs were obtained preoperatively. Perioperative antibiotics and tocolysis were administered.
RESULTS: There were 28 cases of ultrasound-indicated and 14 of physical examination-indicated CC. Positive swab cultures were observed in 21 % of cases. The incidence of preterm delivery <34 weeks was 32 % [95 % confidence interval (CI) 16-52 %] and 50 % (95 % CI 23-77 %) in the ultrasound-indicated and physical examination-indicated CC group, respectively. The incidence of premature rupture of membranes <34 weeks was 21 % (95 % CI 8-41 %) and 29 % (95 % CI 8-58 %) in the ultrasound-indicated and physical examination-indicated CC group, respectively. Perinatal survival was 96 % (95 % CI 88-100 %) in the ultrasound-indicated CC group, and 86 % (95 % CI 67-96 %) in the physical examination-indicated CC group.
CONCLUSIONS: We showed a high-risk of preterm delivery in both groups, but with a high overall perinatal survival. Our data stress the importance of re-evaluating the efficacy of CC in twin pregnancies by properly designed clinical trials, particularly if it is physical examination indicated.
