OBJECTIVE
The purpose of this study was to evaluate the utility of ultrasound surveillance in obese women.
METHODS
This is a retrospective cohort of all obese women who underwent sonography at a single center from 2005-2013. Inclusion criteria were body mass index ≥30 kg/m(2), singleton, ≥1
Twin anemia-polycythemia sequence (TAPS) is a rare condition in monochorionic twin pregnancies. Small intertwin placental vascular communications allow transfusion, which results in a hemoglobin difference in the twins in the absence of oligohydramnios or polyhydramnios. We report here a case of
BACKGROUND
The purpose of this study was to compare obstetric and neonatal outcomes after Roux-en-Y gastric bypass (RYGB) to those in women without such surgery.
METHODS
Women with RYGB (cases) were matched for maternal age and prior cesarean to the next two consecutive women delivering without
OBJECTIVE
To determine clinical characteristics and perinatal outcomes of non-overweight/obese (pre-pregnancy body mass index BMI < 24 kg/m(2)) pregnant women with polycystic ovary syndrome (PCOS).
METHODS
The screening of PCOS was performed when they were at first prenatal visit in Beijing
OBJECTIVE
The purpose of this study is to assess the incidence of oligohydramnios at term and evaluate whether mode of delivery in patients with oligohydramnios influences perinatal outcomes in China.
METHODS
A cross sectional survey of all deliveries in 39 hospitals in China from 1 January to 31
BACKGROUND
Conception is discouraged during the period of maximal weight loss following Roux-en-Y gastric bypass (RYGB) because of speculative maternal and fetal concerns. We therefore performed a retrospective cohort study of obstetrical and neonatal outcomes by surgery-to-conception
Objective: The objectives of this study were (1) to estimate the association between marginal placental cord insertion (PCI) and small for gestational age (SGA) and other adverse perinatal outcomes and (2) to determine if pregnancy-associated plasma protein A (PAPP-A) levels was altered in
Clubfoot is a common structural malformation, occurring in approximately 1/1,000 live births. Previous studies of sociodemographic and pregnancy-related risk factors have been inconsistent, with the exception of the strong male preponderance and association with primiparity. Hypotheses for clubfoot
Prenatal ultrasound is the standard modality to screen for fetal craniofacial malformations, but can be limited by sonographer experience, oligohydramnios, and maternal obesity. Fetal magnetic resonance imaging (MRI) can be used as an adjunct to ultrasound, but there is a paucity of Aside from recognized overgrowth syndromes, instances of visceromegaly are not uncommon at perinatal autopsy. The database of the University of Michigan Teratology Unit was screened for individual viscera exceeding the 90th centile for body and brain weight standards. The data were stratified for
Magnetic resonance imaging has potential as an imaging technique in obstetrics. Its application has been limited by the amount of image degradation that occurs as a result of fetal movement during the long imaging times. By use of a fast-scan imaging technique good images are obtained of fetal
In conclusion, it is unlikely that MRI will replace ultrasound as the primary obstetric imaging modality in the near future. Ultrasound has a proven record of accuracy and safety in addition to its easy access and low cost. MRI has promise, however, in providing crucial information in patients with
One hundred unselected pregnant women underwent M mode and two-dimensional fetal echocardiographic studies between 14 and 43 weeks' gestation. The following cross-sectional views were obtained: high parasternal short axis, parasternal long axis, four chamber view, and an extended long axis to assess
Although US is the mainstay of fetal imaging, magnetic resonance imaging (MRI) has become an invaluable adjunct in recent years. MRI offers superb soft tissue contrast that allows for detailed evaluation of fetal organs, particularly the brain, which enhances understanding of disease severity. MRI
Prenatal ultrasonography is the primary imaging modality in pregnancy as it allows direct real-time fetal examination. Antenatal magnetic resonance imaging (MRI) has so far been of limited clinical value owing to poor image quality. This was due to the long acquisition times that were needed to
