Abstract/OtherAbstract:
BACKGROUND: The incidence of ischemia might be increased in the surgical repair of atherosclerotic unruptured aneurysms compared to non-atherosclerotic aneurysms. The atherosclerotic wall might increase the occurrence of thrombembolic events or its rigidity might endanger the occlusion of perforators within the aneurysm vicinity.
METHODS: 87 patients (53 patients without and 34 patients with atherosclerotic unruptured aneurysms, 50.5±9.7 years) were analyzed for severity of atherosclerosis within the aneurysm and the aneurysm bearing vessel, surgical maneuvers, intraoperative alterations in evoked potentials and clinical and neuroradiological results.
RESULTS: Temporary vessel occlusion (25% vs. 50%, p=0.021), repositioning of a permanent clip (21% vs. 56%, p=0.001) and aneurysm remnants (2% vs. 18%, p=0.012) occurred more often in patients with atherosclerotic aneurysms. At 6 months, 3/34 patients with atherosclerosis (8.8%) had an unfavorable outcome, all patients without atherosclerosis had a favorable outcome (p=0.056).
CONCLUSION: The surgical repair of unruptured aneurysms is safe but patients with atherosclerotic altered vessels and aneurysms accounted to a minor increase in unfavorable outcome and an increased risk of morbidity at 6 months postoperatively. This factor should be taken into consideration when performing surgery of atherosclerotic, unruptured aneurysms.
