title: Chorionic villus sampling after first trimester diagnosis of fetal cystic hygroma colli.
abstract: Diagnostic findings of four cases of cystic hygroma discovered at 11 weeks of gestation are reported. The discovery of cystic hygroma by echotomography was followed by sample taking of chorionic villi which revealed one case of monosomy X and three cases of trisomy 18. Caryotype determination in the presence of cystic hydroma is essential for diagnostic confirmation and subsequent genetic counselling.
