The change in cervical length over time as a predictor of preterm delivery in asymptomatic women with twin pregnancies who have a normal mid-trimester cervical length.
AIM To determine whether or not the change in cervical length (CL) over time is valuable in predicting spontaneous preterm delivery (SPTD) in asymptomatic twin pregnancies with a normal mid-trimester CL (>25 mm). METHODS This was a prospective study including 190 consecutive asymptomatic twin gestations with a CL>25 mm at 20-24 weeks. The women underwent an initial CL measurement at the time ...
متن کاملSonographic measurement of cervical length in twin pregnancies in threatened preterm labor.
OBJECTIVE To determine whether sonographic measurement of cervical length in twin pregnancies presenting with threatened preterm labor helps distinguish between true and false labor. METHODS In 87 women with twin pregnancies presenting with regular and painful uterine contractions at 24-36 (median, 30) weeks of gestation, cervical length was measured by transvaginal ultrasound. Women presenti...
متن کاملRoutine cervical length and fetal fibronectin screening in asymptomatic twin pregnancies: is there clinical benefit?
OBJECTIVE To determine whether routine cervical length (CL) and fetal fibronectin (fFN) screening is associated with improved clinical outcomes in asymptomatic patients with twin pregnancies. STUDY DESIGN We compared outcomes between two large cohorts of twin pregnancies who delivered in New York City from 2003 to 2012. One cohort (n = 532) was managed by a single group practice, delivered at...
متن کاملPrediction of spontaneous preterm delivery in twin pregnancies by cervical length at mid-gestation.
The objective of our study was to evaluate the correlation of the cervical length at 20-25 weeks of gestation with the incidence of spontaneous preterm delivery in twins in a country with a high incidence of preterm delivery compared to other European countries. Cervical length was measured in 262 consecutive patients. Previous preterm delivery before 34 weeks of gestation, chorionicity, matern...
متن کاملPrediction of spontaneous preterm birth in asymptomatic twin pregnancies with the use of combined fetal fibronectin and cervical length.
OBJECTIVE The purpose of this study was to evaluate combined fetal fibronectin (fFN) test result and cervical length (CL) as predictors of spontaneous preterm birth in asymptomatic twin pregnancies. STUDY DESIGN We examined a retrospective cohort of 155 twin pregnancies with combined fFN and CL testing between 22 and 32 weeks gestation. RESULTS A positive fFN test result at 22-32 weeks or a...
