摘要:
目的探讨成人烟雾病患者侧枝循环特点及其临床意义。方法收集2006~2016年在南方医科大学南方医院神经外科接 受DSA检查的成人烟雾病病人资料。根据临床影像学检查分为两组(缺血组和出血组),双盲分析影像学结果,对疾病严重程 度采用改良Suzuki评分(mSS)进行分级。回顾性分析患者脑血管造影图像,把侧支循环血管系统的分组分为浅部脑膜组和深 部脑实质组,浅部脑膜组再分为硬脑膜血管吻合系统和软脑膜血管吻合系统;深部脑实质组分为室管膜下血管吻合系统和丘 脑、纹状体内血管吻合系统。每例病人,根据侧枝循环的有无进行赋值(1表示有侧枝循环,0表示无侧枝循环)。测量和记录后 交通动脉(Pcom)及颈内动脉(ICA)的内径。记录脉络膜前动脉的异常改变:(0表示没显影;1表示显影但无扩张;2表示扩张并 参与代偿供血)。采用spss 22.0软件对数据进行统计学分析,比较组间差异,检验水准均为α=0.05。结果出血组与缺血组间病 人mSS评分的分布没有显著差异(χ2=5.812,v=5,P=0.325);Pcom/ICA(后交通动脉颈内动脉内径比值)比较两组差异有统计学 意义(t=2.119,v=108,P=0.036)出血组Pcom/ICA值较大。Pcom/ICA在不同mSS评分的各组间的分布差异有统计学意义(f= 8.924,P<0.05)mSS评分在等于3、4、5分时比值较大;两组之间脉络膜前动脉扩张的发生率的差异有统计学意义(χ2=11.79,P= 0.001);侧支循环血管系统:硬脑膜血管吻合组:两组之间硬脑膜血管吻合发生率差异没有统计学意义(χ2=0.327,P=0.567)。软 脑膜血管吻合组:两组之间软脑膜血管吻合发生率差异有统计学意义(Fisher精确检验,P=0.018),出血组出现率明显高于缺血 组。室管膜下血管吻合组:两组之间室管膜下血管吻合发生率差异没有统计学意义(χ2=0.011,P=0.917)。纹状体内血管吻合 组:两组之间纹状体内血管吻合发生率差异有统计学意义(χ2=7.551,P=0.006),出血组出现率高于缺血组。结论侧支循环血管 系统是烟雾病患者脑血流重要组成部分,其因病人不同而表现不同的模式;后交通动脉与颈内动脉内径的比值增大,脉络膜前动 脉的异常扩张,发自沟动脉的软脑膜血管吻合和丘脑、纹状体内的血管吻合可能是烟雾病病人出现出血性卒中的独立危险因子。
Abstract:
Objective To investigate the characteristics of collateral circulation in adult moyamoya disease (MMD). Methods The clinical data were collected from all adult patients with MMD undergoing digital subtractive angiography (DSA) in our department from 2006 to 2016. Based on the imaging findings, the patients were divided into ischemia group and bleeding group. A double-blind analysis was conducted of the CT or magnetic resonance imaging findings and the severity of the disease was graded using the modified Suzuki score (mSS). We classified the anastomotic networks in MMD into the superficial meningeal type and deep parenchymal type. The superficial meningeal type was further classified into the leptomeningeal and the durocortical networks, and the deep parenchymal networks into subependymal networks and the inner striatal and inner thalamic networks. Results No significant difference was found in the distribution of mSS scores between the hemorrhage group and the ischemic group (χ2=5.812, v=5, P=0.325), but the posterior communicating artery and internal carotid artery diameter ratio (Pcom/ICA ratio) was significantly greater in the hemorrhage group (t=2.119, v=108, P= 0.036). The Pcom/ICA ratio differed significantly among the groups with different mSS scores (f=8.924, P=0.00), higher in groups with mSS scores of 3, 4 and 5. The incidence of anterior choroidal artery dilation differed significantly between hemorrhage and ischemic groups (χ2=11.79, P=0.001). The incidences of durocortical networks (χ2=0.327, P=0.567) and subependymal networks (χ2=0.011, P=0.917) were comparable between hemorrhage group and ischemic groups, but the incidence of leptomeningeal networks (P=0.018) and inner striatal and inner thalamic networks (χ2=7.551, P=0.006) differed significantly between the two groups. Conclusion The collateral circulation vascular system is an important component of cerebral blood flow in MMD patients and varies from patient to patient. Patients with MMD exhibit increased Pcom/ICA ratio with abnormal expansion of the anterior choroidal artery, and the leptomeningeal networks and the inner striatal and inner thalamic networks are independent risk factors for cerebral hemorrhage.
