The article reports on antepartal sonographic diagnosis and the course and completion of 27 cases with ventral abdominal wall defects. There were 17 cases of omphalocele, 4 cases of gastroschisis and 6 cases of complex ventral abdominal wall defects with associated malformations. In 23 of the 26 women examined prenatally via sonography (89%), the diagnosis was ventral abdominal wall defect. In the 3 cases not diagnosed via sonography, there was one case of intrauterine foetal death. In another case, Potter's syndrome with anhydramnion was found besides a foetal abdominal wall defect, whereas the last unrecognised case had been subjected to sonographic examination outside the hospital only. In 13 out of 17 cases (77%) with omphalocele there were additional malformations. On the other hand, no further associated malformations were seen in the 4 patients with gastroschisis. Complex abdominal wall defects (in the sense of total abdominal wall aplasias or thoracoabdominal gastroschisis, etc.) with multiple associated malformations occurred in the remaining 6 cases. The most frequently seen associated malformations in children with omphalocele were neural tube defects and skeletal malformations (35% each), followed by cardiac and vascular malformations and malformations of the digestive tract. In those women examined in our clinic via sonography who had foetal abdominal wall defects, amniotic anomalies were seen (hydramnion 44%, oligohydramnion 13%). Chromosomal anomalies occurred in omphalocele with 35% incidence. The results obtained point to the necessity of conducting detailed and accurate sonographic examination if a foetal abdominal wall defect is discovered, in order to exclude or confirm further associated malformations.(ABSTRACT TRUNCATED AT 250 WORDS)
