Summary
Stent-graft placement effectively treated saccular aortic aneurysms in two patients, leading to aneurysm disappearance. This minimally invasive approach offers a viable surgical alternative for select aortic aneurysm cases.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Biomedical Engineering
Background:
- Saccular aortic aneurysms pose significant risks, necessitating effective treatment strategies.
- Traditional surgical repair can be invasive with considerable morbidity.
- Minimally invasive endovascular techniques are increasingly explored for aortic pathologies.
Observation:
- Two patients with saccular aortic aneurysms underwent stent-graft placement.
- A Dacron-covered nitinol stent-graft was deployed in the thoracoabdominal and infrarenal abdominal aorta.
- Immediate post-deployment angiograms showed aneurysm sac disappearance.
Findings:
- Successful stent-graft deployment was achieved in both patients.
- Follow-up CT scans confirmed aneurysm thrombosis or complete resolution.
- One patient experienced distal embolization requiring small bowel resection and renal dialysis due to renal infarction.
- Both patients remained alive at 1.5 years and 1 year post-procedure.
Implications:
- Stent-graft placement is a feasible endovascular option for selected patients with saccular aortic aneurysms.
- This technique may offer a less invasive alternative to open surgical repair.
- Careful patient selection and monitoring are crucial to mitigate potential complications like embolization.
