Clinical Outcomes of Large (>10 mm) Unruptured Posterior Circulation Aneurysms and Their Predictors

Objective The treatment of large aneurysms the posterior circulation is complicated and remains challenging. We here analyzed our institutional clinical outcomes unruptured circulation. Methods This study included 56 patients who presented with a (>10 mm) aneurysm between 2002 2018. Results There were 18 (32.1%) male 38 (67.9%) female patients, mean age 53.4 years. most common location was vertebral artery, followed by basilar tip cerebral artery. median follow-up duration 29 months. Eighteen treated transcranial surgery endovascular (EVT). Posttreatment complications occurred in 16 (28.6%), there being no significant difference EVT groups. Complete obliteration achieved 30 (53.6%), statistically Recurrence 17 (30.4%), rate recurrence higher group than (39.5% vs. 11.1%, p=0.03). Forty-four (84%) showed favorable functional outcome. In saccular aneurysm, negative predictor worsening status. Conclusion Treatment these harbors an inherent high risk morbidity. No superiority found terms complete obliteration, but durability EVT.
