Summary
Total arch replacement with frozen elephant trunk successfully treated complex acute type B aortic dissection involving the aortic arch and visceral malperfusion in three patients.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Thoracic Surgery
Background:
- Acute complicated type B aortic dissection (aTBAD) management typically involves medical therapy and endovascular repair.
- Endovascular repair is often not feasible for dissections extending into the aortic arch.
Observation:
- Three patients presented with aTBAD complicated by retrograde extension into the aortic arch and concurrent visceral malperfusion.
- These complex cases posed significant management challenges due to the extent of the dissection.
Findings:
- A novel surgical approach utilizing total arch replacement combined with the frozen elephant trunk technique was employed.
- All three patients were successfully treated with this combined surgical strategy, demonstrating its efficacy in complex aTBAD.
Implications:
- This technique offers a viable solution for managing aTBAD with aortic arch involvement and visceral malperfusion.
- The findings suggest that total arch replacement and frozen elephant trunk may expand treatment options for challenging aortic dissection cases.
