[Ultrasonographic diagnosis of a stenocephalus in combination with intestinal atresia (author's transl)].

Microcephalus and atresia of the small intestines can be demonstrated by ultrasonic examination. Malformations can occur at any time during pregnancy. The reasons for it are hard to find. A single diagnostic including ultrasonic investigations, chromosome analysis and alpha-fetoprotein determination in the amniotic fluid during the first half of pregnancy is unsufficient and leads to pseudosecurity. The ultrasonic investigation by an experienced means a marked enrichment of the prenatal diagnostic. Every ultrasonic examination during pregnancy should consider these diagnostic possibilities.
