Objective

The utilization of endovascular abdominal aortic aneurysm repair (EVAR) in suitable patients has resulted in decreased perioperative morbidity and mortality. Octogenarians as a subgroup have been more readily offered EVAR, as it is less invasive, and therefore presumably better tolerated than conventional open aortic repair. The purpose of this study is to investigate periprocedural and late EVAR outcomes in octogenarians compared with patients less than 80 years of age.

Methods

From January 2003 to May 2008, 322 patients underwent EVAR. A total of 117 octogenarians were compared with 205 patients less than 80 years of age. A retrospective review of the demographic data, aneurysm details, perioperative morbidity, mortality, and late outcomes were analyzed.

Results

Octogenarians were significantly more likely to have a history of diabetes mellitus (51% vs 23%; P < .001), coronary artery disease (45% vs 32%; P = .0165), chronic obstructive pulmonary disease (44% vs 30%; P = .0113), and renal insufficiency (57% vs 31%; P < .0001). There were no significant differences in the rates of perioperative myocardial infarction, stroke, death, intestinal, or arterial ischemic complications between the two groups. Octogenarians had a significant higher rate of pulmonary complications (5.1% vs 1%; P < .03) and access-site hematomas (12% vs 2.4%; P = .001) than younger patients. When all significant perioperative morbidity was combined, octogenarians were twice as likely to develop complications following EVAR than younger patients (27.4% vs 11.7%; P = .001). At 5-year follow-up, younger patients were twice as likely to develop type II endoleaks.

Conclusions

EVAR can be performed safely and effectively in octogenarians, and the incidence of major complications including myocardial infarction, stroke, and death is unchanged compared with younger patients. However, there is a significantly increased rate of access-site hematomas, pulmonary, and perioperative complications in octogenarians as a whole. Our findings suggest EVAR remains a suitable form of therapy in the elderly group provided there is an appropriate preoperative evaluation and perioperative monitoring following repair.
