Summary
This case report details a novel endovascular repair for DeBakey type I ascending aortic dissection. A transseptal approach facilitated precise stent-graft placement, offering a minimally invasive solution for complex aortic pathologies.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Vascular Endovascular Therapy
Background:
- Ascending aortic dissection, particularly DeBakey type I, presents significant therapeutic challenges.
- Conventional surgical repair carries substantial risks, especially in patients with prior cardiac surgery.
Observation:
- A 56-year-old woman with persistent DeBakey type I ascending aortic dissection post-coronary artery bypass grafting was treated.
- A novel transseptal approach was utilized, passing a guidewire from the right femoral vein through the atria and ventricle to the ascending aorta.
Findings:
- Precise stent-graft placement was achieved using the transseptal guidewire technique under adenosine-induced cardiac arrest.
- The endovascular repair successfully closed the aortic rent, addressing the extensive dissection.
Implications:
- The transseptal approach offers enhanced guidewire control for navigating the aortic arch in complex dissections.
- This case demonstrates the feasibility of endovascular repair for ascending aortic pathologies using standard equipment and techniques.
