A rare vascular complication in a preterm neonate: iliac artery injury following patent ductus arteriosus device closure.

Percutaneous closure of patent ductus arteriosus has become increasingly common with advancements in interventional cardiology, especially in preterm infants. However, complications related to vascular access remain a significant concern, particularly in neonates with low birth weight. We reported a case of a 12-day-old preterm infant born at 33 weeks of gestation, who developed a right external iliac artery injury during catheter-based patent ductus arteriosus closure, necessitating emergent surgical intervention. Postoperatively, the patient recovered without signs of ischaemia or neurologic deficit. This case underscores the importance of careful vascular access planning and highlights the potential for serious complications even in technically successful patent ductus arteriosus closures in neonates.
