Amniography in the prenatal diagnosis of neural tube defects.

Amniography for the visualization and confirmation of suspected neural tube defect was performed in 9 midtrimester gravidas. In all cases, amniotic fluid alpha-feto protein (AFP) was abnormally elevated. Four cases of anencephaly and one of spina bifida were demonstrated by amniography. These pregnancies were terminated and the defects were confirmed by gross pathologic examination. In 4 remaining cases, amniography was normal. Three of these pregnancies proceeded to term, culminating in the birth of a normal child. The fourth patient had spontaneous abortion of a normal fetus at 23 weeks of gestation. The experience reported here suggests that amniography is an important adjunctive diagnostic technique in the prenatal diagnosis of neural tube defect, and if used correctly, may significantly reduce the chance of false-positive diagnosis.

Passage of feeding catheters into the pleural space: a radiographic sign of trauma to the pharynx and esophagus in the newborn.

Although rarely recognized, traumatic pharyngeal and cervical esophageal pseudodiverticula are probably not infrequent in newborns who have undergone vigorous oropharyngeal suctioning and endotracheal intubation. This report describes four premature infants with clinically unsuspected retroesophageal false passages incidentally discovered on chest radiographs. Differentiation of pseudodiverticula from spontaneous rupture of the middle or distal esophagus can be achieved by careful inspection of the course of the feeding catheter in frontal and lateral projections and by partial withdrawal of the catheter to permit injection of the retroesophageal false passage with a small volume of water-soluble contrast material.

Prenatal diagnosis of neural tube defects.

A prospective program for the prenatal detection of neural tube defects in a high-risk pregnancy group has been under way for one year. Twenty high-risk mothers have undergone a complete prenatal work-up, including sonography, amniocentesis, and amniotic fluid and maternal serum alpha-fetoprotein quantitation. Within this group, two cases were prospectively diagnosed and were later confirmed.
