Comparison of cognitive function and quality of life after endovascular orconventional aortic aneurysm repair

Introduction: The long-term effects of endovascular aortic aneurysm repair on cognitive function and quality of life are not known. Methods: The cognitive function and quality of life of 82 patients undergoi ng aortic aneurysm repair (34 endovascular and 48 conventional procedures) were assessed before and 6 months after operation. Cognitive function was q uantified using a battery of psychometric tests. Quality of life was assess ed with the Medical Outcomes Short Form 36 (SF-36) questionnaire. Results: 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 t est (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 af ter 6 months in cognitive function or quality of life. Conclusion: Endovascular aneurysm surgery had a similar impact on health-re lated quality of life and cognitive function compared with conventional ane urysm repair. Patients in both groups demonstrated a significant decline in cognitive function.
