Abstract
Purpose - to present characteristic features of prenatal ultrasound imaging in omphalocele among patients of the Department of Fetal Medicine, to describe most common typical variants. Material and methods. A retrospective analysis of 201 ultrasound examinations in 150 patients with omphalocele in the fetus, which were referred to the Department of Fetal Medicine in 2007-2018. Results. The most common typical variants of ultrasound imaging/anatomical variants of omphalocele in the fetus are presented. According to hernia content there were following frequent variants: “intestine” in 48.15 %, "intestine + liver" in 31.11 %, "intestine + liver + stomach" in 15.56 %, "liver" in 5.19 %. A working classification of omphalocele by size is proposed and 4 gradations are distinguished: small, medium, large and giant. Incidence of chromosomal pathology was significantly higher in small-sized omphalocele (44 %) and rate of associated structural pathology was high in large (54.5 %) and giant omphalocele (72.7 %). Conclusion. The study showed significant variability of size and anatomical variants of omphalocele in the fetus. In 44.9 % of cases anatomical variants of severe pathology with large or giant size omphalocele were present. Key words: congenital malformations, abdominal wall defects, variants of omphalocele, chromosomal pathology.
