[ENDOVASCULAR ABDOMINAL AORTIC ANEURISM REPAIR]

Area of Science:

• Vascular Surgery
• Endovascular Interventions
• Aortic Aneurysm Treatment

Background:

• Severe somatic pathology often contraindicates open surgery for abdominal aortic aneurysms.
• Abdominal aortic aneurysms (AAAs) pose significant risks, especially in patients with comorbidities.
• Traditional open repair carries high risks for patients with complex health issues.

Purpose of the Study:

• To evaluate the safety and efficacy of endovascular stent-graft repair for abdominal aortic aneurysms (AAAs) in patients with severe comorbidities.
• To assess the outcomes of stent-graft implantation in a high-risk surgical population.
• To determine the feasibility of avoiding open conversion in this patient group.

Main Methods:

• Single-center analysis of 72 patients with abdominal aortic aneurysms (diameter 41-84 mm) and severe comorbidities.
• Endovascular repair using stent-grafts as the primary treatment modality.
• Follow-up included ultrasound and computed tomography, with a mean follow-up of 44.6 months.

Main Results:

• Successful stent-graft implantation in all 72 patients, with no need for open surgery conversion.
• No increase in aneurysm sac size or endoleaks observed during follow-up.
• Aneurysm size reduction of 4-5% in the first year post-operation for 37 patients.

Conclusions:

• Stent-graft implantation is a safe and effective treatment for abdominal aortic aneurysms in patients deemed high-risk for open surgery.
• Endovascular repair expands treatment options for complex AAA cases, improving outcomes in challenging patient populations.
• This approach offers a durable solution, preventing aneurysm expansion and leakage in the medium term.
