DSA在烟雾病诊断中的临床应用研究

目的探讨烟雾病DSA检查的影像学表现及临床意义。方法回顾性分析26例确诊烟雾病患者临床及DSA影像学资料。结果26例患者DSA影像学特征如下:脑底异常烟雾状血管网形成;受累动脉狭窄或闭塞;丰富侧支循环形成。其中单/双侧大脑前、中及后动脉均存在不同程度的狭窄或闭塞性病变者24例(92.3%);双侧颈内动脉床突上段狭窄或闭塞者18例(69.2%),单侧者7例(26.9%)。结论烟雾病患者有显著的DSA影像学特征,DSA是诊断烟雾病的主要手段,临床上对疑似病例应早行DSA检查明确诊断。

Clinical significance of DSA on moyamoya disease

Objective To investigate clinical significance of DSA on moyamoya disease. Methods Examinationresults of DSA 26 patients diagnosing moyamoya disease were analyzed retrospectively. Results DSA features of 26 moyamoya disease patients were as follows ： various degrees of abnormal vascular networks at the base of the brain, artery involvement were stenosis or occlusions and abundant collateral circulation. In 24 patients, unilateralor bilateral anterior cerebral artery, middle cerebral artery and posterior cerebral artery existed various degreesof stenosis or occlusive lesions. 18 patients were bilateral internal carotid arteries stenosis or occlusions on the distal segments, and in 7 patients were affected on one side. Conclusion DSA is the main method of moyamoya diseasediagnosis, in patients clinically suspected of having this disease DSA should be performed as early as possible.
