Abstract

Objective: To examine and discuss patients diagnosed with acquired and congenital chylothorax in the neonatal period in the light of the literature.

Methods: The files of newborns followed-up in the neonatal intensive care unit (NICU) and diagnosed with congenital and acquired chylothorax were reviewed retrospectively. Patients with isolated chylothorax were classified as Group 1 and those with multiple lymphatic flow disorders were classified as Group 2. Antenatal and clinical features were recorded and compared between the groups.

Results: Thirteen infants were diagnosed with chylothorax; 92.3% (n = 12) of the patients were congenital. The rate of antenatal diagnosis was 61.5% (n = 8). Eight patients (61.5%) were diagnosed with hydrops fetalis. Among the cases in Group 1 and Group 2, receiving ocreotide and the incidence of sepsis (p = 0.05) were partially significant. Seven of the patients (66.6%) responded to medium chain triglycerides (MCT), and complete resolution was seen in 6 (85.7%) of the responders. Complete resolution of chylothorax fluid was observed in 7 (77.7%) of nine patients who responded to ocreotide treatment.

Conclusions: In neonatal chylothorax, the postnatal period includes a multidisciplinary approach that requires drug therapy, dietary modifications, drainage of pleural fluid, and rarely, surgery.

Keywords: Chylothorax; Lymphatic flow disorder; Newborn.
