Relationship between second-trimester uterine artery Doppler and spontaneous early preterm delivery.
OBJECTIVE To evaluate the relationship between impedance to flow in the uterine arteries at 22-24 weeks and subsequent spontaneous delivery before 33 weeks. METHODS The pulsatility index (PI) in the uterine arteries was measured by transvaginal sonography at 22-24 weeks in 33,629 women with singleton pregnancies attending for routine antenatal care. The distribution of PI in the 237 patients ...
متن کاملIs there a role for cervical assessment and uterine artery Doppler in the first trimester of pregnancy as a screening test for spontaneous preterm delivery?
OBJECTIVE To evaluate the role of cervical length (CL) and uterine artery pulsatility index (UtA-PI) at 11+0 to 13+6 weeks as predictors of spontaneous preterm delivery (sPTD) in a Chilean population. METHODS This was a prospective study of asymptomatic women with singleton pregnancies attending for a nuchal translucency scan at 11+0 to 13+6 weeks' gestation and who underwent a transvaginal s...
متن کاملCorrelation between First and Second Trimester Uterine Artery Doppler Velocimetry and Placental Bed Histopathology
Aim. To evaluate the relationship between uterine artery Doppler indices and placental bed histopathology independent of clinical outcome. Materials and Methods. Uterine artery measurements were performed to 510 pregnant women who had come for routine antenatal care in 11-14th and 20-24th weeks. Placental bed biopsies from 141 cases were taken during cesarean section. Physiological changes and ...
متن کاملThe Role of Uterine Artery Doppler Ultrasound in the Second Trimester in Predicting Preeclampsia
Background Preeclampsia is a specific pregnancy syndrome. Early diagnosis and proper administration of preeclampsia can lead to improved maternal and neonatal outcome. We aimed to investigate the uterine artery Doppler ultrasound in predicting the preeclampsia in women with a high-risk pregnancy. Materials and Methods This analytic study was conducted on 160 primigravida women with gestational...
متن کاملFirst-trimester uterine artery Doppler and adverse pregnancy outcome: a meta-analysis involving 55,974 women.
OBJECTIVES To determine the accuracy with which uterine artery Doppler in the first trimester of pregnancy predicts pre-eclampsia and fetal growth restriction, particularly early-onset disease. METHODS We searched MEDLINE (1951-2012), EMBASE (1980-2012) and the Cochrane Library (2012) for relevant citations without language restrictions. Two reviewers independently selected studies that evalu...
