Prognosis of fetuses with cystichygroma and nuchal translucency/nuchal fold thickening on prenatal echography / 浙江大学学报·医学版

ABSTRACT

OBJECTIVE@#To analyze the prognosis of fetuses with cystic hygroma (CH) or nuchal translucency (NT) or nuchal fold (NF) thickening detected by prenatal echography.@*METHODS@#From January 2014 to December 2015, 124 fetuses with CH and NT/NF thickening on prenatal echography were enrolled from Women's Hospital of Zhejiang University School of Medicine. The basic clinical information, ultrasonic results, pregnancy outcomes and newborn follow-ups were analyzed. The cases were grouped by prognosis and the factors affecting prognosis were analyzed with logistic regression.@*RESULTS@#There were 85 cases of labor induction including one stillbirth and 39 cases delivered. Except one infant who died after birth, all live births survived with good prognosis. Univariate analysis showed that the gestational age at diagnosis of poor prognosis group was earlier than that of good prognosis group (<0.01); and the former group also had higher hydrops fetalis rate and additional structural anomalies rate (all <0.01). Multivariate regression analysis showed that hydrops fetalis (=90.105, <0.05) and additional structural anomalies (=61.854, <0.05) were risk factors of poor prognosis in fetuses with CH and NT/NF thickening.@*CONCLUSIONS@#Fetuses with diagnosed CH or NT/NF thickening on prenatal ultrasonography are likely to be associated with chromosomal abnormality. Early gestational weeks, hydrops fetalis and additional structural anomalies may indicate poor prognosis.
