摘要未破裂颅内动脉瘤（UIA）在我国35~75岁成人中的患病率约7%。随着人口老龄化趋势，UIA检出率增加。大多数UIA是偶然发现的，通常无症状，选择手术治疗还是保守治疗一直存在争议。尽管UIA的年破裂风险低，但一旦发生破裂，其致死率和致残率高。本临床管理指南基于循证证据，围绕UIA的人群筛查、临床影像诊断、生长破裂风险评估、治疗策略及选择、术后随访和特殊人群UIA管理建议等方面，共形成44条推荐意见，旨在为临床医师、其他相关专业人员提供实用的临床指导建议。

abstractsUnruptured intracranial aneurysm (UIA) has an estimated prevalence of about 7% among adults aged 35-75 in China. With the aging population trend, the detection rate of UIA is increasing. Most UIA are incidentally discovered and typically asymptomatic. There has been ongoing debate regarding the choice between aggressive treatment and conservative management. Although UIA has a low annual risk of rupture, once rupture occurs, the mortality and disability rates are high. Based on evidence-based medicine, this clinical management guideline provides 44 recommendations on population screening, clinical imaging diagnosis, risk assessment of growth and rupture, treatment strategies and selection, postoperative follow-up, and management of special populations with UIA. Aiming to provide clinical guidance for clinical doenrs and relevant professionals.
