title: [Retrocervical cystic hygroma: diagnosis, prognosis and management. A series of 13 cases].
abstract: Fetal cystic hygroma (CH) are congenital malformation of the lymphatic system which are seen in antenatally ultrasonography from the end of the first trimester of pregnancy. From a 13 CH retrospective study, the authors discuss the ultrasound diagnosis, the prognosis and the management of CH. In our study, CH is associated with lymphedema (69%), hydrops (46%), diminution of amniotic fluid (69%) and other abnormality (31%). In all cases a diminution or an absence of fetal movement are found. In seven cases a cytogenetic analysis are performed on amniocentesis or fetal tissues: there are five 45XO, one 47XX + 13 and one 46XX. In six cases the chromosome culture failed: two male phenotypes and two histologic appearances of chromosomic anomaly. The prognosis depends on chromosome analysis, other ultrasound abnormality and the size of CH. It is usually fatal in utero. If chromosome anomaly are found, a genetic counsel is proposed.
