有研究发现,颅内动脉瘤在Moyamoya综合征患者中患病率约14.2%,而其在普通人群的患病率仅约5%[1]。相对于普通颅内动脉瘤患者,Moyamoya综合征患者的颅内动脉瘤破裂预后更差,所以防治此类颅内动脉瘤破裂或再破裂显然非常重要。目前合并Moyamoya综合征颅内动脉瘤治疗方法有两种,即外科手术夹闭和介入栓塞治疗。前者为常规治疗方法,但由于颅内动脉瘤多存在于复杂及脆弱 Some studies have found that the prevalence of intracranial aneurysms in patients with Moyamoya syndrome is about 14.2%, while its prevalence in the general population is only about 5% [1]. Relative to the conventional intracranial aneurysm patients, Moyamoya syndrome patients with intracranial aneurysm rupture prognosis worse, so the prevention and treatment of such intracranial aneurysm rupture or rupture is clearly very important. Currently there are two ways to treat intracranial aneurysms with Moyamoya syndrome, namely surgical clipping and interventional embolization. The former is a routine treatment, but due to the presence of intracranial aneurysm complex and fragile
