BACKGROUND: Congenital chylothorax is a rare pulmonary developmental disorder with high associated morbidity and mortality. A limited number of cases have been described, and clinical manifestations and outcomes vary.
METHODS: This study aims to delineate the neonatal and long-term outcome of patients with congenital chylothorax by retrospective and prospective data collection at Ghent University Hospital in Belgium between 1992 and 2022.
RESULTS: Eighteen patients with congenital chylothorax were included, seven of whom had a pathology-confirmed diagnosis of congenital pulmonary lymphangiectasia. Of 16 patients with prenatal diagnosis, four underwent an intra-uterine intervention. Thirteen patients were born prematurely. The most common comorbidities were hydrops (8/18), pulmonary hypertension (3/18), and reflux disease (6/18). One patient was diagnosed with Noonan syndrome. The majority of patients (14/18) required mechanical ventilation. Treatment included pleural drainage (15/18), total parenteral nutrition (14/18), medium-chain triglyceride diet (11/18), somatostatin (8/18), and surgical intervention (3/18), with a median hospital stay of 59 days. Three patients died during or after the neonatal period. Follow-up ranged from 6 months to 30 years, with most patients reporting good general health but variable respiratory complaints. Five out of eight respiratory function tests showed mild abnormalities. Follow-up chest CT showed persistent changes in all but two patients up to a maximum age of 16 years. Health-related quality of life was similar to healthy controls.
CONCLUSION: Congenital chylothorax demonstrates a variable neonatal course. Long-term outcomes are generally favorable in patients without comorbidities, although mild pulmonary function and chest CT abnormalities persist in the majority of patients.
