Chapter 18 - Fetal Gastrointestinal and Abdominal Abnormalities (Content last reviewed: 15th February 2018)

from Section 3 - Late Prenatal – Fetal Problems


Fetal gastrointestinal and abdominal wall malformations are easily visualized by ultrasound and may be detected either during a second-trimester scan for anomalies or by chance during an examination for an unrelated indication, such as the evaluation of poor fetal growth, abnormal amniotic fluid volume (usually polyhydramnios), or an increased maternal serum α-fetoprotein (MSAFP). Increasingly these abnormalities are being detected on late first-trimester scanning.
