Objectives. The aim of this study was to establish nomograms for fetal stroke volume (SV), cardiac output (CO), and ejection fraction (EF) using four-dimensional ultrasound with spatio-temporal image correlation (STIC) modality.Methods. heart scanned STIC modality, starting classic four-chamber view plane, during quiescence abdomen uppermost, at an angle 20–30°, without color Doppler flow mapping. In post-processing virtual organ, computer-aided analysis technique used obtain a sequence six...
To assess intracranial structure volumes by 3-dimensional (3D) sonography in fetuses with growth restriction.We conducted a prospective cross-sectional case-control study involving 59 restriction (38 estimated weight <3rd percentile and 21 between 3rd 10th percentiles, according to Hadlock et al [Radiology 1984; 150:535-540]) 54 controls 24 34 weeks' gestation. The following fetal were assessed: cerebellum, brain, frontal region. volume was assessed 3D using the extended imaging virtual...
Amniotic band syndrome is characterized by a build-up of bands and strings fibrous tissue that adhere to the fetus can compress parts fetus, thus causing malformations even limb amputation while still in uterus. The clinical manifestations are extremely variable their extent may range from single abnormality, like constriction ring, multiple abnormalities. Such abnormalities generally diagnosed at end first or beginning second trimester using two-dimensional ultrasonography (2DUS)....
Abstract Aim The aim of this study was to evaluate the passage fetal erythrocytes into maternal circulation after invasive obstetric procedures, using K leihauer– B etke test, flow cytometry and α‐fetoprotein concentration in blood. Material Methods This a prospective descriptive on patients who underwent: amniocentesis, cordocentesis, chorionic villus sample, amniotic infusion, bladder drainage ventricular–amniotic shunt investigate karyotype; treatment for hydrocephalus, oligohydramnios,...
To evaluate the modified myocardial performance index (Mod-MPI) in foetuses with growth restriction and compare this appropriate for gestational age foetuses.A prospective cross-sectional case-control study was conducted involving 76 singleton between 24 34 weeks of gestation divided into three groups (24 foetuses, 30 estimated weight 3rd 10th percentiles 22 < percentile, according to Hadlock table). The Mod-MPI obtained plane four chamber view, spectral Doppler sample volume placed lateral...
To evaluate the mode of delivery according to Robson classification (RC) and perinatal outcomes in fetal growth restriction (FGR) small for gestational age (SGA) fetuses.
Fetal growth restriction (FGR) is defined as the inability of fetus to reach its potential for genetic determination. FGR can have several causes, including syndromes, chromosomal diseases, and infections; however, a vast majority cases are probably attributed impaired uterine placental circulation. The relationships between abnormal development complex, studies generally few, presenting confounding factors. Damage uteroplacental circulation associated with vasculogenesis villus angiogenesis...
Schizencephaly is a brain-destructive lesion relating to clefts in the fetal brain that usually communicate with ventricular system, subarachnoid space, or both. It presents as two types: Type I (closed) and II (open). During pregnancy, it may be suspected course of ultrasonography, which highlights dilatation abnormalities. Usually, diagnosis confirmed postnatally using trans-fontanel ultrasonography. The etiology schizencephaly still unknown, but derived from primary disorder development...
THE EEC SYNDROME IS A GENETIC ANOMALY CHARACTERIZED BY TRIAD: ectodermal dysplasia (development of anomalies the structures derived from embryonic layer), ectrodactyly (extremities, hands and feet malformations) cleft lip and/or palate; these malformations can be seen together or in isolation. The prenatal diagnosis made by two-dimensional ultrasonography (2DUS) that identifies facial limb anomalies, most characteristic being "lobster-claw" hands. three-dimensional (3DUS) provides a better...
To establish reference ranges of the fetal adrenal gland (AG) and zone (FZ) volumes using three-dimensional ultrasound (3DUS).We performed a prospective cross-sectional study with 204 normal singleton pregnancies between 24 37 + 6 weeks gestation. The AG FZ were obtained virtual organ computer-aided analysis method 30° rotation. as function gestational age (GA), quantile regression was adjusted coefficient determination (R2). Intra- inter-observer repeatability intraclass correlation...
Cloacal malformation is an extremely rare fetal pathological condition that presents as a variety of defects. It predominantly affects females, with prevalence 1 in 50,000 births. Prenatal ultrasonography on 20-year-old caucasian woman (G4P1A2) at 33 weeks pregnancy showed the fetus having large cystic mass lower abdomen single septum, bilateral hydronephrosis, ambiguous genitalia, and umbilical artery. The developed accentuated oligohydramnios, presence brain-sparing effect was diagnosed...
The aim of this study was to assess the Doppler parameters ophthalmic artery pregnant women carrying fetuses with growth restriction (FGR) compared normal fetuses.A prospective cross-sectional conducted 120 (60 FGR and 60 fetuses) between 32 40 weeks gestation. diagnosis based on an estimated fetal weight below 10th percentile Hadlock curve. Ophthalmic images were obtained a linear transducer, color examination region medial optic nerve. following indices obtained: pulsatility index,...
Objective: To assess the usefulness of estimating fetal upper arm and thigh volumes as predictors low postnatal body mass index (BMI) using three-dimensional ultrasonography (3DUS) with extended imaging virtual organ computer-aided analysis (XI VOCAL).Methods: This prospective cross-sectional study analyzed 300 singleton pregnancies between 33 41 weeks gestation. The Hadlock 4 formula was used to estimate weight. XI VOCAL 10 planes method volumes. After delivery, newborns’ BMI evaluated...
The present study aimed to evaluate the performance of QuantusFLM® software, which performs quantitative ultrasound analysis fetal lung texture, in predicting maturity fetuses diabetic mothers.The patients included this were between 34 and 38 weeks 6 days gestation divided into two groups: (1) with diabetes on medication (2) control. images performed up 48 h prior delivery analyzed using classified each fetus as high or low risk for neonatal respiratory morbidity based immaturity.A total 111...
