Insights
Iatrogenic type A aortic dissection (TAAD) is a rare complication of angiography. Endovascular stent graft repair successfully treated retrograde TAAD originating from the subclavian artery, with favorable long-term outcomes.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Vascular Surgery
Background:
- Iatrogenic type A aortic dissection (TAAD) is a rare complication following invasive cardiovascular procedures.
- Coronary angiography can precipitate TAAD, posing a significant risk to patient safety.
Observation:
- A unique case of retrograde TAAD originating from the right subclavian artery after coronary angiography is presented.
- The dissection propagated retrogradely, presenting a complex endovascular challenge.
Findings:
- Successful endovascular closure of the iatrogenic entry tear using a stent graft was achieved.
- The intervention led to resolution of the false lumen and promoted favorable aortic remodeling.
- The patient experienced no cardiovascular events during a 4-year follow-up period.
Implications:
- This case demonstrates the feasibility and effectiveness of endovascular treatment for retrograde TAAD.
- Subclavian artery origin TAAD can be managed successfully with endovascular techniques.
- Minimally invasive approaches offer a promising alternative for managing iatrogenic aortic injuries.
Abstract:
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.
