【摘要】 目的　探讨烟雾病并发颅内出血的DSA表现特征。方法　 19例患者均经CT诊断为颅内出血 ,经股动脉穿刺插管行全脑血管造影。结果　 19例脑血管造影均为烟雾病表现 ,具有下列特征 :1受累动脉狭窄或闭塞 ;2颅底部烟雾状毛细血管网 ;3大量的侧支循环形成。结论　CT检查一般只能提示颅内出血的部位 ,而DSA检查是诊断烟雾病的主要手段 ,具有明显优势更多还原

【Abstract】 Objective To explore the DSA mainfestations of MoyaMoya disease.Methods 19 patients, underwent CT before DSA, showed intracranial hemorrhage. All patients were then examined by angiography via femoral artery approach. Results All cases were diagnosed as MoyaMoya disease through DSA. The findings of DSA showed characteristic manifestations as the following: 1. Stenosis or occlusion of the invoved arteries. 2. Smoke like capillary vascular network spreading from supraseller cistern to cerebral base. 3. Development of collateral circulation. Conclusions DSA is the main method for the diagnosis of MoyaMoya disease, CT can only localize the site of cerebral hemorrhage.更多还原
