Long-Term Outcomes of 92 Cases of Fetal Hydrothorax Including Thoracoamniotic Shunting

2019 
BACKGROUND: There have been no previous reports on the postnatal course, especially long-term outcomes, of fetal hydrothorax patients, including those treated with thoracoamniotic shunting (TAS) using a double-basket catheter.The outcomes of cases from a single center are reported. METHODS: Cases of fetal hydrothorax managed at our center between 2005 and 2015 were enrolled retrospectively. TAS was performed if indicated. Long-term outcomes such as cerebral palsy, developmental disabilities, and others were analyzed. RESULTS: Ninety-two cases of fetal hydrothorax were included. The causes were primary chylothorax, transient abnormal myelopoiesis, cardiac disease, pulmonary sequestration, mediastinal neoplasm, and infection. TAS was performed in 36 cases. Early neonatal death occurred in 19 cases. The 28-day survival rates for all cases and for TAS cases were 70% (48/69) and 72% (26/36), respectively. Of the cases that underwent TAS, one was treated with home oxygen therapy, one was diagnosed with cerebral palsy and severe intellectual disability, and five were diagnosed with mild or moderate developmental disabilities. CONCLUSIONS: The results showed that the survival rate and long-term outcomes of cases with hydrothorax have improved as TAS has become more prevalent. The reasons for these results need to be elucidated, and efforts are needed to further improve outcomes.
