Summary
Endovascular repair of abdominal aortic aneurysms (AAA) using straight endografts is safe and effective. The "trombone technique" showed slightly lower rates of reintervention and endoleak compared to single endografts.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Aortic Aneurysm Treatment
Background:
- Eight-year experience with endovascular techniques (ET) for abdominal aortic aneurysms (AAA).
- Focus on treatment using straight endografts.
Purpose of the Study:
- Evaluate the safety and effectiveness of endovascular repair for AAA using straight endografts.
- Compare outcomes between single straight endografts and the "trombone technique".
Main Methods:
- Retrospective review of 53 patients treated for AAA between 1998 and 2012.
- Group A: single straight endograft; Group B: double straight tube ("trombone technique").
- Analysis of survival, endoleak, and reintervention rates; statistical comparison using Log-rank and Chi-Square tests.
Main Results:
- 53 patients treated with straight endografts.
- 28 patients (52.8%) received a single aortic straight tube (Group A).
- The remaining patients were treated with the "double trombone technique" (Group B).
Conclusions:
- Endovascular repair of AAA with straight aortic endografts is a safe and effective procedure.
- Slightly higher rates of reintervention and endoleaks observed in the single endograft group compared to the "trombone technique" group.
