Patent ductus arteriosus ligation in an extremely low birth weight preterm infant

This patient was born at 25th week of gestation with extremely low birth weight (700 grams) and hyaline membrane disease. On his 9th day as neonate, he was diagnosed to have a patent ductus arteriosus (PDA). Due to pulmonary congestion/ hypertension on top of failure of the said PDA to close after a regimen of ibuprofen and subsequently indomethacin, surgical intervention was contemplated which however was delayed because of the onset of pneumonia and bronchopulmonary dysplasia. On the 59th day of life, PDA ligation was done at the Nursery ICU. The patent weighted 800 grams at his supposed to be 33- 34 weeks age of gestation making him the smallest infant to be reported who have underwent PDA ligation in the Philippines.
