Povidone-Iodine Pleurodesis for Chylothorax in an Extremely Low Birth Weight Infant

Abstract

Chylothorax, the accumulation of chyle in the pleural space, is a rare condition, but can lead to serious complications in neonates. Conservative therapy for chylothorax includes enteral feeding with medium-chain triglyceride-enriched diet or parenteral nutrition and administration of octreotide. Surgical management is considered in cases where there is no response to conservative therapy; however, the standardized approach to refractory neonatal chylothorax is still controversial. Chemical pleurodesis can be used when medical therapies for chylothorax fail, to avoid more invasive surgical procedures. We report an extremely preterm infant born at 26 weeks of gestation with refractory chylothorax after patent ductus arteriosus ligation. The infant was successfully treated with pleurodesis using 4% povidone-iodine, without long-term side effects.
