Endovascular vs. Open Surgery of Abdominal Aortic Aneurysm in High-Risk Patients: A Single Center Experience[1]

Abstract

Background: We compared two groups of high-risk patients with abdominal aortic aneurysm to assess the safety and efficacy of endovascular repair vs. open surgery. Methods: From January 1998 to July 2003, sixty-two high-risk patients were divided into two groups: group A consisted of 28 (46 %) open surgery patients and group B consisted of 34 (54 %) patients who underwent endovascular repair. Results: Four patients (14.3 %) in the open surgery group died, while no deaths occurred in the endovascular group (p < 0.05). There were 14 complications in 8 patients of the open surgery group versus 2 complications in 2 patients of the endovascular group (p = 0.01). At follow-up there were 4 (16.6 %) deaths in group A and 3 (8.8 %) in the endovascular group (p = n. s.). Conclusions: While the use of endovascular repair in patients who are physiologically fit for open surgical repair remains controversial, we believe that patients with multiple or advanced comorbidities, i.e. high-risk patients, can benefit from the endografting procedure.
