A total of 64 patients (9.70%) experienced at least one complication, corresponding to 65 complication events. Early complications occurred in 33 patients (5.0%), whereas late complications were observed in 31 patients (4.70%). The overall technical complication rate was 3.03%, and the clinical complication rate was 6.82%. Secondary interventions were required in 39 patients (5.91%). Procedure-related mortality and morbidity rates were 0.76% and 4.55%, respectively. Technical complications include stent shortening\/migration, stent deformation, stent fracture, stent layer separation, and distal wire dissection. Clinical complications include intimal hyperplasia causing significant stenosis, stent occlusion, carotid-cavernous fistula, thromboembolic events, hemorrhagic events, and rare events such as non-ischemic cerebral enhancing (NICE) lesions and diffuse alveolar hemorrhage.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Flow diversion represents an effective reconstructive strategy for intracranial aneurysms, demonstrating durable long-term occlusion in a large single-center cohort.
