Prophylactic cerclage in women with previous spontaneous premature deliveries associated with ascending bacterial infection Cerclaje profiláctico en mujeres con nacimientos prematuros espontáneos previos, asociados con infección bacteriana ascendente

Abstract

Aims: Determine the effectiveness of prophylactic cerclage in women with singleton pregnancies, cervix >25 mm and a history of spontaneous premature deliveries associated to ascending bacterial infection (ABI). Methods: Women with singleton pregnancies and history of preterm births, with no full-term deliveries, associated to ABI. Cases with ?25 mm cervical length at admission were included. Cervical cerclage performed on patients derived before 20 weeks of pregnancy was compared to the expectant management of women submitted at a later gestational stage with sustained cervical length of >25 mm. Pregnant women with <25 mm cervix at referral, with cervical shortening <25 mm at expectant management, and women with previous preterm birth without placental histology were excluded. Results: 51 patients were included, 23 with cerclage and 28 without cerclage. Prophylactic cerclage significantly reduced the frequency of premature birth <37 weeks, 4.3% vs 35.7% and <34 weeks, 4.3 % vs 28.6 % a
