Comparison of cognitive function and quality of life after endovascular or conventional aortic aneurysm repair.

Abstract

The long-term effects of endovascular aortic aneurysm repair on cognitive function and quality of life are not known. The cognitive function and quality of life of 82 patients undergoing aortic aneurysm repair (34 endovascular and 48 conventional procedures) were assessed before and 6 months after operation. Cognitive function was quantified using a battery of psychometric tests. Quality of life was assessed with the Medical Outcomes Short Form 36 (SF-36) questionnaire. Data at 6 months were available for 78 per cent of patients. As a group the patients showed a significant decline on one cognitive function test (visual search) and on two domains of the SF-36 (physical function and vitality) when they were reassessed. There were no significant differences between patients undergoing endovascular or conventional aneurysm repair after 6 months in cognitive function or quality of life. Endovascular aneurysm surgery had a similar impact on health-related quality of life and cognitive function compared with conventional aneurysm repair. Patients in both groups demonstrated a significant decline in cognitive function.
