Abstract Objective Many published studies have shown that application of three‐dimensional (3D) and real‐time 3D (4D) ultrasound modalities can improve certain aspects fetal echocardiography, but left open the question whether these improved accuracy prenatal detection anatomical cardiovascular malformations. We aimed to determine 3D/4D diagnostic ability in cases congenital heart disease (CHD). Methods Women who attended for early‐ or midtrimester targeted organ scans had complete...
Agenesis of the ductus venosus (ADV) is a rare condition in which there are two variants umbilical vein drainage: intrahepatic shunt or extrahepatic (portosystemic) shunt. It has been posited that variant carries poorer prognosis. However, absence associated anomalies still wide variation outcome. We evaluated portal system cases ADV and aimed to identify parameters might predict outcome.We conducted retrospective study with had examined centers, collected new prospectively. The route was...
To describe and assess the presence of a new indirect sign partial agenesis corpus callosum (pACC): an abnormally shaped cavum septi pellucidi (CSP).We analyzed retrospectively images from all 71 cases pACC seen at two referral centers between September 2006 April 2014. Abnormally CSP was diagnosed when its lateral dimension greater than anteroposterior in axial transthalamic plane, incidence this assessed. We also examined following variables: gestational age referral, indication for which...
To identify the genetic basis of a recessive syndrome characterized by prenatal hyperechogenic brain foci, congenital microcephaly, hypothalamic midbrain dysplasia, epilepsy, and profound global developmental disability.Identification responsible gene whole exome sequencing homozygosity mapping.Ten patients from 4 consanguineous Palestinian families manifested in utero with intrauterine growth retardation. Postnatally, had progressive severe neonatal seizures, virtually no milestones. Brain...
Examination of the fetal venous system is a necessary part complete organ scanning to confirm landmark anatomy, such as ductus venosus and course umbilical veins, and, whenever cardiovascular anomalies are identified, exclude associated anomalous development veins. We aimed develop protocol for systematic examination during midtrimester targeted scanning.We included low-risk women with singleton fetus presenting between January 2011 June 2013 our center routine (20-24 weeks) scanning....
Estimation of fetal heart ventricular mass is important for cardiac evaluation in cases structural or functional disorders extracardiac factors. It may be used with other parameters to ascertain the severity and prognosis such disorders, nature timing intervention. We applied a novel technique combining spatiotemporal image correlation (STIC) three-dimensional inversion mode Virtual Organ Computer-aided AnaLysis (VOCAL™) assessment healthy fetuses second third trimesters.STIC acquisition was...
BACKGROUND: The sliding sign (the relative motion between the abdominal and uterine wall as assessed by ultrasonography) may help identify severe intra-abdominal adhesions before repeat cesarean delivery. METHODS: We conducted a prospective observational study of scheduled deliveries. Using transabdominal ultrasonography, while parturient breathed deeply, ultrasonographer recorded video clip in sagittal plane lateral to umbilicus. These clips were for presence (sliding-positive) or absence...
Abstract Objective To evaluate the role of placental blood flow measurements by simultaneous multigate spectral Doppler imaging in pregnancies complicated intrauterine growth restriction (IUGR), and for early detection vascular abnormalities highhyphen; low‐risk pregnancies. Methods assess sensitivity specificity abnormal detecting IUGR, we followed 22 women whose were IUGR at 28–34 weeks' gestation, compared findings with those obtained matched controls. We defined impedance as when 10%...
Abstract Objective To propose, in cases with coiling of the ovarian vessels, a classification severity torsion based on Doppler and gray‐scale ultrasound findings to suggest treatment strategy for each situation. Methods Seventeen patients were examined gynecological emergency room between December 1995 February 2003 due suspected adnexal torsion. used visualize blood vessels. Intraovarian flow was assessed by spectral this basis, along patient's clinical condition, decision made as whether...
Repeat cesarean delivery (CD) accounts for approximately 15% of all annual deliveries in the US with an estimated 656,250 operations per year. We aimed to study whether prolonged operative time (OT; skin incision closure) is a risk marker post-operative maternal complications among women undergoing repeat CD.We conducted cross-sectional retrospective single tertiary center including who underwent CD but excluding those hysterectomy. Prolonged OT was defined as duration longer than 90th...
We aimed to evaluate the use of spatiotemporal image correlation (STIC) as a tool for training nonexpert examiners perform screening examinations fetal heart by acquiring and examining STIC volumes according standardized questionnaire based on 5 transverse planes heart.We conducted prospective study at 2 tertiary care centers. Two sonographers without formal in echocardiography received theoretical instruction echocardiographic planes, well technology. Only women with conditions allowing...
As sonography matures, with its constant technological advances and ever-growing base of experienced examiners, it is reasonable to expect that sensitivity specificity in the diagnosis fetal anomalies will increase. Perhaps most dramatic advance has been introduction three-dimensional (3D) real-time 3D (4D) ultrasound imaging1-7, which have become common adjuncts examinations many centers. In echocardiography, 4D modality applied widely assessment structure function spatiotemporal image...
Abstract Objective To establish gestational age‐specific nomograms of pulsatility indices in the umbilical artery and chorionic intraplacental vessels, using novel ultrasound technology. Study design A prospective, cross‐sectional study 160 healthy singleton pregnancies between 18 33 weeks gestation. Measurements Using simultaneous multigate spectral Doppler imaging specialized hardware software, we measured flow velocity waveforms artery, vessels. Computerized automatic mapping calculated...
To assess whether women with mild gestational thrombocytopenia have a higher risk of postpartum hemorrhage.A retrospective computerized database. Primiparous that delivered at our center (2005-2019) were included; we excluded possible etiologies for such as systemic lupus or coagulation disorders, and hypertensive disorder pregnancy. Demographics, obstetric characteristics, maternal well neonatal data compared between groups. The exposure measure the study was (100,000-150,000) versus normal...
<i>Aim:</i> To determine the effect of a copper-medicated intrauterine device (IUD) on ovarian, uterine, arcuate, radial and subendometrial Doppler-derived indices blood flow. <i>Method:</i> 23 regularly menstruating patients requested insertion an IUD. All had copper T (Nova T) IUD inserted between days 8 11 menstrual cycle. Ovarian, artery pulsatility (PIs) were assessed by transvaginal color Doppler prior to cycle, after 2 months in same period PIs considered...
Introduction Sonographic investigation of the fetal venous system has developed rapidly since its introduction in mid-1980s. Elucidation normal anatomy, role fetal development and evaluation management intrauterine growth restriction (IUGR) other cardiovascular disorders, as well association a part complex structural anomalies, are subjects intensive research.
