Early and Mid-term Results of Endovascular Treatment of Abdominal Aortic Aneurysm in Patients Over 65 Years of Age

Abstract

Objective: In patients over the age of 65, the most appropriate treatment modality for abdominal aortic aneurysms (AAA) is controversial, but the use of endovascular treatment methods is increasing. The aim of this study was to investigate the duration of intensive care unit stay, need for reintervention, and early and late mortality rates after endovascular treatment in octogenerians with abdominal aortic aneurysm. Material and Method: A total of 220 patients who underwent endovascular aneurysm repair for abdominal aortic aneurysm under elective conditions were included in the study. Patients over 70 years of age constituted Group-1 (n = 102) and those under 70 years of age constituted Group-2 (n = 118). The groups were analyzed in terms of postoperative intensive care stay, need for reintervention, and early and late mortality rates. Results: The ratio of males was higher in group 1 (94.5% vs. 84.9, p = 0.017). Length of ICU stay was higher in group 1 (12 hours vs. 8 hours, p = 0.014). All four cases of early mortality were in patients over 65 years of age (p = 0.031). There was no difference between the groups in terms of follow-up period (32 vs. 31 months, p = 0.859), late mortality (8% vs. 13%, p = 0.219), or the need for secondary intervention (6% vs. 7%, p = 0.770). There was no difference between the groups in terms of survival and the 3-year survival was 91% vs. 85%. (p = 0.199). Conclusion: In octogenerians, endovascular aneurysm repair can be performed with acceptable mortality rates and satisfactory mid-term outcomes.
