Patent ductus arteriosus may be closed with which management approach?

• A. It may be closed with medications or surgical intervention
• B. It never requires treatment
• C. It closes spontaneously within minutes in all cases
• D. It is always associated with cyanosis

Answer: (A)

Closure of a patent ductus arteriosus is achieved through medications or surgical intervention when it remains open after birth. After birth, the ductus normally constricts, but if it stays open, especially when it’s large, it can cause excess pulmonary blood flow and strain on the heart. For many infants, drugs that reduce prostaglandin synthesis promote closure; NSAIDs such as indomethacin or ibuprofen are commonly used, with acetaminophen as an alternative option in some cases. If medical closure isn’t possible or is unsafe, surgical ligation or a catheter-based device closure can seal the duct. Spontaneous closure can occur, particularly in smaller infants, but it cannot be relied upon in all cases or within minutes. Cyanosis isn’t an inherent feature of PDA and depends on the overall hemodynamics.
