A thoracic aortic endoprosthesis collapsed, causing a proximal leak and symptoms. A second graft successfully re-expanded the device, resolving the issue and leading to a good outcome.
Area of Science:
- Vascular Surgery
- Cardiovascular Imaging
Background:
- Thoracic aortic aneurysms require endovascular repair.
- Graft sizing is critical for successful thoracic endoprosthesis implantation.
Observation:
- A 40-year-old male presented with hypertensive crisis and pulmonary edema 6 months post-aortic endoprosthesis implantation.
- Imaging revealed endoprosthesis collapse and a proximal type I leak.
Findings:
- A second thoracic endoprosthesis (TAG graft) was successfully deployed within the collapsed device.
- Re-expansion of the endoprosthesis achieved symptom resolution.
Implications:
- This case highlights the potential for endoprosthesis collapse in thoracic aortic repair.
- Successful re-intervention demonstrates a viable salvage strategy for endoprosthesis failure.
- Careful graft sizing and monitoring are essential for long-term thoracic endoprosthesis outcomes.
