未破裂颅内动脉瘤的研究进展

Progress of unruptured intracranial aneurysms

未破裂颅内动脉瘤(UIA)多因患者出现头痛或头晕等不适而行头颅影像检查时发现。UIA在普通人群中的患病率为1%~2%,但UIA的相关机制及破裂风险尚不统一,其中,动脉瘤性蛛网膜下腔出血(SAH)是较为严重的并发症,越来越引起人们的关注。因此,了解UIA破裂的影响因素、并发症发生率以及干预效果很重要。本文就UIA的患病率、危险因素、影像学监测作用以及UIA的筛查、治疗等进行综述。

Most of the unruptured intracranial aneurysms(UIA)are found accidentally under cranial imaging examination when the patients have headache or dizziness.The prevalence of UIA in the general population is about 1%-2%,but the UIA-related mechanisms and risks of rupture cannot be explained.Aneurysmal subarachnoid hemorrhage(SAH)often leads to catastrophic consequences,which draws attention increasingly.Therefore,it is very important for clinicians to understand the influencing factors for rupture,the incidence of complications and the outcome of intervention.The prevalence of UIA,risk factors,roles of imaging monitoring,screening and treatment of UIA are reviewed in this paper.
