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...
Objective: The objective of this study is to evaluate the predictive performance Fetal Medicine Foundation (FMF) algorithm for prediction preeclampsia (PE) between 11 and 14 weeks gestation in an unselected Brazilian population.Methods: We conducted a prospective cohort with 617 singleton pregnancies risk. Biophysical markers (mean pulsatility index, mean arterial pressure) biochemical (placental growth factor (PLGF) PAPP-A) were inserted into FMF software converted multiples median (MoM)....
To determine the prevalence and clinical significance of amniotic fluid "sludge" (AFS) in asymptomatic patients at low high risk for spontaneous preterm delivery.A prospective cohort study was conducted on 195 singleton pregnancies or birth (PTB) between 16th 26th weeks. Cervical length (CL) <25 mm presence AFS were evaluated. The delivery before 28, 32, 35 37 weeks determined according to AFS, CL < 25 history PTB. Stepwise logistic regression performed compare variables.AFS an independent...
To determine reference ranges for measurements of fetal cerebral fissures by 3-dimensional (3D) sonography in the multiplanar mode and to evaluate reliability concordance these measurements.A cross-sectional study was conducted on 393 women with normal pregnancies at 22 weeks 33 6 days. The distances between internal bone plate calvaria sylvian, parieto-occipital, hippocampal, calcarine were assessed. obtain first 3 fissures, a 3D sweep made axial plane, level lateral ventricles. distance...
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...
RhD alloimmunization in pregnancy is still the main cause of hemolytic disease fetus and neonate (HDFN). Nevertheless, there are other antigens that may be associated with occurrence this phenomenon have been growing proportion, given current prevention strategies focus only on anti-RhD antibodies. Although not widespread, […]
Objective. The purpose of this study was to assess the reliability and validity in vitro volume calculations by 3-dimensional ultrasonography. Methods. This observational performed 2 examiners obtain volumes 3 objects different shapes sizes filled with ultrasound gel immersed water. used multiplanar (5-mm interval), virtual organ computer-aided analysis (VOCAL, 30°) extended imaging (XI) VOCAL (5, 10, 15, 20 planes) methods estimate each object. A paired Student t test (P) intraclass...
To determine reference range for fetal interventricular septum area by means of 3-dimensional ultrasonography (3DUS) using the spatiotemporal image correlation (STIC) method.A prospective, cross-sectional study was conducted on 328 normal pregnant women between 18th and 33rd gestational weeks. obtain area, a virtual plane used, with green line (region interest) adjacent to external margin septum, which manually delimited. evaluate age, different regression modes were evaluated. The...
This study aims to determine reference curves for fetal atrioventricular valve areas by means of three-dimensional ultrasound using the spatiotemporal image correlation (STIC) software.This was a cross-sectional prospective on 328 normal fetuses between 18th and 33rd weeks pregnancy. In order obtain areas, four heart chambers plane used with fetus in dorsal posterior position. To construct ranges, linear regression model used, adjusted according coefficient determination (R(2)). calculate...
Heterotopic pregnancy is a condition characterized by implantation of one or more viable embryos into the uterine cavity while another implanted ectopically, particularly tube. Its occurrence has increased drastically over last few years due to assisted reproduction procedures. In general, diagnosis made during first trimester using endovaginal two-dimensional ultrasound (2DUS), through observing complex para- retrouterine mass in association with pregnancy. However, under some conditions...
Preeclampsia (PE) is an important cause of maternal and perinatal mortality worldwide, accounts for 10% to 15% direct deaths, 99% these deaths are in low-income countries.
