Prenatal obstruction of the ileum diagnosed by ultrasound

A case of low atresia of the ileum, diagnosed prenatally by real-time ultrasound scanning, is presented. The ultrasound examination showed progressive distension of intestinal loops, with strong peristaltic movements. The stomach was also distended, presenting as a large cystic area in the upper left abdomen. Real-time ultrasound technique is most advantageous in the diagnosis of fetal ileus. Prenatal diagnosis of fetal intestinal obstruction is of great importance, making early and safe treatment of the newborn possible.     

Prenatal diagnosis of laryngeal atresia

Prenatal diagnosis of congenital atresia of the larynx is difficult but is possible by the findings of increased lung echogenicity and size coexisting with fetal ascites in ultrasonography. Sonographic findings may not always be typical. We report on a case of congenital laryngeal atresia diagnosed prenatally by the findings of fetal hydrops and hyperechogenic lungs. Our case presented with oligohydramnios. We also review syndromes that demonstrate laryngeal anomalies. Copyright © 2003 John Wiley & Sons, Ltd.     

Amniotic fluid analysis in a fetus with laryngeal atresia

Complete laryngeal atresia is a rare congenital malformation that is known to cause hypertrophy of the fetal lung in utero. A fetus with laryngeal atresia was found to have markedly immature amniotic fluid lung maturity studies at term. Inappropriately low amniotic fluid lung maturity studies may be an important clue to the diagnosis of this condition.
