OBJECTIVE The purpose of this study was to compare the diagnostic performance of ultrasonographic and digital examination of the cervix in the prediction of preterm delivery in patients presenting with preterm labor and intact membranes. STUDY DESIGN Endovaginal ultrasonography was performed in 59 patients admitted with preterm labor (20 to 35 weeks) and(More)
OBJECTIVE The aim of this study was to determine the value in the prediction of spontaneous preterm delivery of ultrasonographically measured cervical length measured between 14 and 24 weeks' gestation. STUDY DESIGN A retrospective cohort study examined cervical length by means of a two-stage procedure, transabdominal ultrasonography followed by(More)
PURPOSE The prenatal or postnatal factors that predict complex gastroschisis in patients (atresia, volvulus, necrotic bowel and bowel perforation) remain controversial. We evaluated the prognostic value of prenatal ultrasonographic parameters and early postnatal factors in predicting clinical outcomes. METHODS We analyzed maternal and neonatal records of(More)
OBJECTIVE The aims of this study were to determine if there is a relationship between middle cerebral artery (MCA) peak systolic velocity (PSV) and perinatal mortality in preterm intrauterine growth-restricted (IUGR) fetuses, to compare the performance of MCA pulsatility index (PI), MCA-PSV and umbilical artery (UA) absent/reversed end-diastolic velocity(More)
OBJECTIVE First-trimester fetuses with simple nuchal hygromas represent a population that is different from midgestation nuchal cystic hygroma in terms of karyotype abnormalities and long-term prognosis. STUDY DESIGN Sixty-eight consecutive fetuses diagnosed with simple nuchal hygromas between 10 and 14 weeks' gestation were evaluated ultrasonographically(More)
OBJECTIVE The purpose of this study was to determine whether a repeated antenatal ultrasound examination improves fetal cardiac visualization for the obese and nonobese population. METHODS A computerized ultrasound database (October 1999-June 2003) was used to identify singleton pregnancies undergoing repeated prenatal ultrasound examinations because of(More)
OBJECTIVE To examine the impact of maternal obesity on the rate of suboptimal ultrasound visualization (SUV) of fetal anatomy and determine the optimal timing of prenatal ultrasound examination for the obese gravida. METHODS A computerized ultrasound database was used to identify ultrasound examinations for singleton gestations performed between 14(0/7)(More)
OBJECTIVE Our purpose was to determine whether cerclage placement in women with a short cervix on transvaginal ultrasonography reduces the rate of preterm delivery. STUDY DESIGN A retrospective cohort study identified patients with an ultrasonographic short cervix (cervical length < or =15 mm) between 14 and 24 weeks' gestation. Cerclage placement was(More)
OBJECTIVE This study was undertaken to describe a new technique for the examination of the fetal heart using four-dimensional ultrasonography with spatiotemporal image correlation (STIC). STUDY DESIGN Volume data sets of the fetal heart were acquired with a new cardiac gating technique (STIC), which uses automated transverse and longitudinal sweeps of the(More)
OBJECTIVE The purpose of this study was to determine the prevalence and clinical significance of microbial invasion of the amniotic cavity in patients presenting with cervical dilatation in the midtrimester of pregnancy. STUDY DESIGN Amniocentesis for microbial studies was performed in women admitted with cervical dilatation > or = 2 cm, intact membranes,(More)
