Endovascular stent grafts as a safe secondary option for paraanastomotic abdominal aortic aneurysm

Objective. To describe our experience of endovascular repair of paraanastomotic aortic aneurysm. Methods and results. From March 2001 to December 2004 we identified 6 patients with a paraanastomotic aortic aneurysms following previous open repair of abdominal aortic aneurysm. All patients were treated with endovascular surgery under epidural anaesthesia. There were no major complications, surgical conversions or deaths. Four patients received a bifurcated aortic stent-graft, and two an aorto-uniliac stent-graft followed by a femoro-femoral bypass. At follow-up (mean 26.1 +/- 10.2 months) there were no deaths, endoleaks or graft migrations observed. Conclusion. Endovascular surgery, avoiding general anesthesia and re-laparotomy, is the ideal technique for treatment of this complication resulting from failed primary conventional AAA repair.
