Refractory Congenital Chylous Ascites Successfully Treated with Sildenafil in a Premature Neonate: A Case Report and Review of The Literature

Abstract Chylous ascites is a scarce disorder in the neonatal period caused by lymph leakage into the peritoneal cavity. It may develop congenitally or acquired. Here we report that a 30-week-old premature infant with congenital chylous ascites did not respond to various treatments, and there was a dramatic improvement with the addition of sildenafil. With this case report, we wanted to emphasize that sildenafil should be in the mind of the clinicians as a treatment option in the treatment of resistant chylous ascites.
