Aortic Dissection (AD) causes a fatal cardiovascular emergency due to an intimal breach in the aorta, leading to the separation of the aortic wall layers either antegrade or retrograde results in development of a true and false lumen that will eventually compromise blood flow to the affected vital organs. On the other hand, PDA device closure repair has become an established safe intervention with an excellent post-procedure outcome. However, complications post-procedure have been reported, with vascular-related complications although rare but deems significant when it happens. We reported a case of chronic Stanford B Aortic Dissection with Aortic Arch Aneurysm following the history of PDA Device Closure repair. Its pathophysiology is described based on device-duct disproportions, foreign body inflammatory reactions and aortic wall chronic irritation. Although it’s considered rare, there were few published case reports on similar events reported as acute and chronic aortic dissection. This case aims to look upon the relationship of Aortic Dissection as a rare but possible complication post PDA Device Closure Repair procedure.
