[Endoluminal stent-graft for aortic aneurysms: a report of six cases]
Insights
Endovascular stent-graft repair of aortic aneurysms is a feasible treatment. This minimally invasive approach effectively excludes aneurysms from circulation, offering a potential alternative for high-risk patients.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Medical Devices
Context:
- Aortic aneurysms pose significant health risks, often requiring surgical intervention.
- Traditional open repair carries substantial risks, particularly for elderly or comorbid patients.
- Endovascular techniques offer a less invasive alternative for treating aortic pathologies.
Purpose:
- To evaluate the clinical efficacy and feasibility of endovascular stent-graft prostheses for treating aortic aneurysms.
- To assess the short-term outcomes and potential complications associated with this endovascular approach.
Summary:
- Six patients with various aortic aneurysms underwent endovascular repair using stent-grafts.
- Procedures involved placement of bifurcated or straight stent-grafts via femoral artery access under fluoroscopic guidance.
- All patients achieved primary technical success, with complete exclusion of aneurysms from circulation observed during 2-16 months of follow-up.
Impact:
- Endovascular aortic aneurysm repair demonstrates technical feasibility and effectiveness in excluding aneurysms.
- This approach may become a valuable interventional strategy, especially for patients with infrarenal aortic aneurysms who are poor surgical candidates.
- Further research and refinement of endovascular techniques are warranted to optimize patient outcomes.
Objective:
To explore the clinical value of the treatment of aortic aneurysms with endovascular stent-graft prostheses.
Methods:
Six patients were included in the study. 4 patients with infrorenal abdominal aneurysms involving the aortic bifurcation and the common iliac arteries received bifurcated stent-grafts; 1 patient with descending and abdominal aortic aneurysm received straight stent-graft; and 1 patient with right common iliac artery aneurysm received straight stent-graft. After a unilateral surgical arteriotomy, the endoprostheses were advanced through the femoral arteries and placed under the guidance of fluoroscope. CT and MRI were perfomed during the follow-up of 2-16 months.
Results:
All patients got a primary success. The aortic aneurysms were completely excluded from the circulation. Two cases had a prolonged fever; 1 case was found a leakage 3 months later.
Conclusion:
Our results suggest that endovascular treatment of aortic aneurysm is technically feasible and it can effectively exclude aortic aneurysms from the circulation. With further refinement, endoluminal repair may emerge as an interventional strategy to treat infrarenal aortic aneurysm, especially for patients at high surgical risk.
