This retrospective cohort study compares ibuprofen treatment versus expectant management for hemodynamically significant patent ductus arteriosus (hsPDA) in preterm infants. Data were collected from preterm infants with hsPDA admitted to the Department of Neonatology, Shengjing Hospital of China Medical University between June 2020 and June 2025. A total of 541 infants were included: 241 received ibuprofen and 300 received expectant management (no routine pharmacological closure, supportive care only). The primary outcome is PDA closure rate. Secondary outcomes include bronchopulmonary dysplasia (BPD), mortality, pulmonary hypertension, renal insufficiency, neonatal pneumonia, retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH), pulmonary hemorrhage, and gastrointestinal bleeding. Analyses are stratified by gestational age (\<28 weeks, 28-33 weeks, 33-37 weeks) and adjusted for sex, multiple gestation, and maternal factors. The study aims to provide real-world evidence on the risks and benefits of ibuprofen closure in different gestational age subgroups.
