Prenatal diagnosis of cystic hygroma cases in a tertiary centre and retrospective analysis of pregnancy results.

The aim of this study is to retrospectively examine invasive diagnostic methods, structural anomalies accompanying cystic hygroma, and pregnancy outcomes in cystic hygroma cases admitted to a tertiary centre. The population of the study consisted of 29 live foetuses with cystic hygroma in the foetal neck only in the first or second trimester. In the study, pregnant women who applied to our centre were included. Amniocentesis or chorionic villus sampling was performed for genetic analysis according to the weeks of the pregnant women who were diagnosed with cystic hygroma by ultrasound examination by two clinicians experienced in foetal anomaly. Of the pregnant women included in the study, 10 had normal karyotype, 12 had abnormal karyotype and 13 had structural abnormality. It is very important to provide genetic counselling to the families of foetuses with cystic hygroma with a multidisciplinary team approach consisting of neonatologists, paediatric surgeons and experienced sonographers
