Passage / Scenario
A child with patent ductus arteriosus (PDA)Surgical repair for patent ductus arteriosus (PDA) is done to prevent the complication of
Correct answer
A
Rationale
The correct answer is A: Increased pulmonary vascular congestion. Surgical repair of PDA is done to prevent the complication of increased pulmonary vascular congestion. This is because in a PDA, there is a persistent connection between the aorta and the pulmonary artery, leading to increased blood flow to the lungs, causing congestion. By closing the PDA surgically, the excess blood flow to the lungs is reduced, preventing pulmonary vascular congestion.
Choice B is incorrect because repairing a PDA does not necessarily decrease the workload on the left side of the heart. Choice C is incorrect as pulmonary infection is not a direct complication of PDA. Choice D is incorrect as a right-to-left shunt of blood is not a typical complication of PDA.
