The authors investigated the incidence of chromosomal abnormalities in cases where subcutaneous oedema was detected in the fetus by intrauterine ultrasonography. Intrauterine karyotyping in case of fetal subcutaneous oedema was carried out in 434 cases. Chromosomal investigation was performed for nuchal oedema in 374 cases. In 120 patients the chromosomal examination was carried out in the first-trimester following nuchal translucency examinations, and in 254 cases in the second-trimester after detection of nuchal thickening. Cystic hygroma (27 patients), nonimmune hydrops (20 patients), and combination of nonimmune hydrops and cystic hygroma (13 patients) cases were investigated separately. In cases of nuchal oedema, pathological karyotypes were detected in 8.33% in the first trimester and in 5.51 % in the second trimester. Chromosomal abnormalities were found in 48.15%, 20%, and 53.8% in cases of cystic hygroma, non-immune hydrops, and combined occurrence of non-immune hydrops and cystic hygroma, respectively. Considering all the changes that were accompanied by subcutaneous oedema, 50%, 25% and 18.75% of the pamological karyotypes were X monosomy, trisomy 18 and trisomy 21, respectively. The authors emphasize the differentiation between the various types of subcutaneous oedema and the importance of obtaining precise information about the risks, provided during genetic counselling.
