Successful Endovascular Entry Closure for Retrograde Type A Aortic Dissection Originating from the Right Subclavian Artery: A Case Report

抄録

Iatrogenic type A aortic dissection (TAAD) is a rare but potentially fatal complication of coronary angiography. We report a case of iatrogenic retrograde TAAD originating from the right subclavian artery. Endovascular entry closure using a stent graft led to resolution of the false lumen and favorable aortic remodeling. The patient remained free from cardiovascular events over a 4-year follow-up. This case highlights the potential efficacy of endovascular treatment, even in retrograde TAAD with its entry located in the subclavian artery.
