AIM: To analyse the main prenatal and postnatal features of congenital chylothorax (CC), and the outcome including mid-term follow-up. METHODS: We searched our databases for CC diagnosed between 1990 and 2006. Data of 29 cases were retrieved and analysed. Follow-up until 3 years of age was available for all patients. RESULTS: Most patients were diagnosed prenatally (94%) and most cases were complicated by foetal hydrops (66.7%). The overall survival rate at 3 years was 56%. A significantly poorer outcome was observed when foetal hydrops, preterm birth < 34 weeks, large effusions and/or early-onset pneumothorax were present. An important but not significant improvement in the survival rate was observed through the study period; while in 1990-1998, the survival rate was 41.7%, from 1999 to 2006 it was 66.7% (p = 0.19). In the mid-term follow-up, we did not observe any recurrence of CC and most infants remain asymptomatic. However, 27% of survivors were diagnosed as having asthma in early infancy. CONCLUSION: CC still carries a significant risk of perinatal mortality. However, continuous advances in foetal and neonatal medicine are improving the prognosis of these patients, and nowadays most of them are likely to survive. Beyond the neonatal period, most survivors have an uneventful outcome.
