Between January 2015 and September 2022, 9116 patients with intracranial aneurysms came to our institution for management, of which 34 patients with 34 large (\u226510 mm) BTAs were treated with endovascular treatment.

Neurological complications occurred in 12 (35.3%) patients, with 7 (20.6%) deaths. Ischemic complications occurred in 10 (29.4%) patients, and 4 (11.8%) patients experienced hemorrhagic events. The incidences of favorable outcomes at discharge and last follow-up were 85.3% and 75.8%, respectively. The cumulative survival rates at 1 and 3 years were 86.5% and 71.4%, respectively. Unilateral vertebral artery sacrifice was associated with postprocedural complications (hazard ratio: 3.74, 95% confidence interval: 1.06\u201313.25,\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.041).
