OBJECTIVE To evaluate the effectiveness of a novel approach to the visualization of the fetal secondary palate using three-dimensional (3D) ultrasound. METHODS Sonographic examinations were performed in normal fetuses and in one fetus with cleft lip and palate. To avoid acoustic shadowing from the alveolar ridge, the secondary palate was insonated at a 45(More)
OBJECTIVE To investigate the effectiveness of a simplified approach to the evaluation of the midline structures of the fetal brain using three-dimensional (3D) ultrasound. METHODS Sonographic examinations were performed in normal fetuses and in cases with anomalies involving the midline cerebral structures. Two-dimensional (2D) median planes were obtained(More)
PURPOSE OF REVIEW The purpose of this review is to summarize recently published studies on noninvasive diagnosis of fetal anemia in order to give recommendations for the use of these new tools. RECENT FINDINGS Red cell alloimmunization remains one of the most common causes of fetal anemia. Amniocentesis and cordocentesis have been used for many years to(More)
OBJECTIVE To identify criteria useful for differentiating closed from open spina bifida antenatally. PATIENTS AND METHODS A retrospective study of cases of spina bifida diagnosed in a referral center between 1997 and 2004. RESULTS Of 66 cases of fetal spina bifida diagnosed at a median gestational age of 21 (range, 16-34) weeks, detailed follow-up was(More)
OBJECTIVE Assessment of the middle cerebral artery (MCA) peak systolic velocity (PSV) can accurately diagnose fetal anemia and has decreased the number of invasive procedures, such as amniocentesis and cordocentesis. The objective of this investigation was to evaluate the intraobserver and interobserver variability as a measure of reproducibility of MCA(More)
OBJECTIVE To assess the feasibility of the prenatal diagnosis using fetal neurosonography of brain injuries in the surviving fetus after the demise of a monochorionic cotwin. METHODS This was a retrospective observational study in the period 1990-2004 of monochorionic twin pregnancies with a single fetal demise. A detailed sonographic evaluation of the(More)
OBJECTIVE The aim of this study was to determine the platelet count in fetuses undergoing cordocentesis for hydrops caused by parvovirus infection. STUDY DESIGN Fetal platelets were measured at cordocentesis in 11 pregnant women who underwent the procedure because of fetal ascites and/or hydrops caused by parvovirus infection. Thrombocytopenia was defined(More)
OBJECTIVE To evaluate the usefulness of uterine artery Doppler in the prediction of outcome in patients with late-onset preeclampsia. STUDY DESIGN Patients with late-onset preeclampsia underwent Doppler interrogation of the uterine arteries. Patients with abnormal uterine artery Doppler were compared with those who had a normal uterine artery Doppler. (More)
