The safety, feasibility, and clinical and angiographic outcomes of these procedures were retrospectively evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The average maximum diameter of the fusiform aneurysms was 12.1\u2009mm. Five were ruptured. Three aneurysms were treated with a single stent and the remaining 10 aneurysms required double-stent placement. Treatment was technically successful in all 13 patients, achieving complete occlusion ( n\u2009=\u200910, 76.9%) and near-complete occlusion ( n\u2009=\u20093, 23.1%). No procedure-related complications occurred in any patient. There were no delayed thromboembolic or hemorrhagic complications during the follow-up period (mean, 19.0 months). Angiographic follow-ups (mean, 9.1 months) showed stable occlusion in 90.9% (10\/11) and asymptomatic in-stent occlusion in one patient (9.1%, 1\/11). At the end of the observation period (mean, 19.0 months), all patients had excellent clinical outcomes (modified Rankin Scale (mRS) 0, 92.3%, 12\/13), except one (mRS 4), resulting from poor preoperative status.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This retrospective
