OBJECTIVE To present the appearance of the fetal akinesia deformation sequence by three-dimensional ultrasonography after four-dimensional ultrasonographic scanning. METHODS Three-dimensional surface-rendering images were used to show the fixed postural abnormalities of the fetal extremities and body. Four-dimensional ultrasonography was used to show that the postural abnormalities were fixed...

OBJECTIVE To describe a prenatal diagnostic method for evaluating spina bifida by three-dimensional ultrasonography. METHODS Two- and three-dimensional ultrasonography were used to determine the extent of vertebral defects among fetuses with spina bifida. Spinal levels were independently counted from the most caudal thoracic vertebra with a rib (e.g., 12th thoracic rib). A virtual cutting pla...

Urinary tract abnormalities are frequently detected during obstetrical ultrasonography (US). However, hypospadia is often missed on prenatal US, despite it being the most common congenital defect of the male external genitalia. The prenatal recognition of hypospadias is important because it will alert the physician to order karyotyping and to look for any possible associated dysmorphic syndrome...

Congenital cystic adenomatoid malformation (CCAM) is a rare condition which is easily detectable by prenatal ultrasonography. Fetuses with large CCAMs associating with hydrops are predisposed to perinatal mortality, therefore prenatal intervention is required. While macrocystic CCAM is treated prenatally by thoracentesis or thoraco-amniotic shunt, microcystic or mixed CCAM is difficult to manag...

OBJECTIVE To review the efficacy of routine prenatal ultrasonography for detecting fetal structural abnormalities. DESIGN Retrospective study of the ultrasonographic findings and outcome of all pregnancies in women scanned in 1988-9. SETTING Maternity ultrasonography department of a district general hospital. SUBJECTS 8785 fetuses. MAIN OUTCOME MEASURES Correlation of prenatal ultrasono...

Congenital hypophosphatasia is a rare fatal skeletal dysplasia. Antenatal determinants of Epub ahead of print lethality include small thoracic circumference with pulmonary hypoplasia and severe micromelia. These features were present in the fetus of a 25-year-old female who came for an anomaly scan in her second trimester of pregnancy. Additional findings of generalized demineralization and ost...

INTRODUCTIONS The widespread use of prenatal ultrasonography results in increased recognition of congenital hydronephrosis, a therapeutic and diagnostic challenge. This study was conducted to investigate the natural course of prenatal hydronephrosis and the accuracy of postnatal APD in determining the outcome. MATERIALS AND METHODS All newborns with prenatal hydronephrosis were followed up by...
