Ultrasonographic diagnosis and perinatal management of fetal abdominal wall defects.
Thirty-four fetuses with ultrasonographically diagnosed abdominal wall defects are described. In 20 out of the 25 (80%) cases with omphalocele, there were associated abnormalities, mainly chromosomal defects (48%), cardiac (28%), genitourinary (20%), craniofacial (20%) and diaphragmatic anomalies (12%). In gastroschisis, associated structural anomalies occurred in 2 out of 5. The 4 cases of abdominal wall defects as a part of amniotic band syndrome were associated with multiple severe defects. No chromosomal defects were found in the group with gastroschisis and amniotic band syndrome. Intrauterine fetal death occurred in 8 cases. Sixteen pregnancies were electively aborted because of an association with an anomaly incompatible with postnatal life; 3 pregnancies were electively terminated on their parents' own request. Two infants died shortly after birth. Seven infants were successfully treated. When level I ultrasound examination demonstrates a fetal abdominal wall defect, a detailed level II ultrasound examination is recommended to exclude associated malformations. In case of omphalocele, prenatal chromosome analysis is indicated. Delivery in a tertiary care center is recommended. A randomized prospective trial is needed to see whether cesarean section or vaginal delivery is the preferred mode of delivery for these infants.
