目的进一步提高对烟雾病的理解和认识。方法收集本院30例证实为烟雾病患者MSCTA影片(包括原始轴位影片、VR、MIP、MPR后处理影片),结合脑血管造影结果及文献资料进行分析。结果 30例患者中均有不同程度颈内动脉系统狭窄及闭塞,单侧者10例,双侧者20例;大脑后动脉狭窄或闭塞者9例;大脑后动脉及颈外动脉系统侧支循环形成20例;合并动脉瘤者11例。所有病例均可见异常血管网,部分患者行DSA检查,结果基本一致。结论烟雾病为脑底动脉进行性狭窄、闭塞及广泛侧支循环形成的疾病,它不仅累及颈内动脉系统,还累及椎-基底动脉系统和颈外动脉系统。MSCTA可代替DSA作为烟雾病的首选检查方法。
Objective To further improve understanding and understanding of moyamoya disease. Methods A total of 30 MSCTA films (including original axial films, VR, MIP and MPR post-treatment films) were collected from 30 patients in our hospital and analyzed with the results of cerebral angiography and literature data. Results All 30 patients had stenosis and occlusion of internal carotid artery in varying degrees, 10 cases of unilateral and 20 bilateral cases, 9 cases of posterior cerebral artery stenosis or occlusion, and the collateral circulation of posterior cerebral artery and external carotid artery Formed in 20 cases; 11 cases with aneurysm. All cases were abnormal vascular network, some patients underwent DSA examination, the results are basically the same. Conclusions Moyamoya disease is a progressive cerebrovascular artery stenosis, occlusion and extensive collateral circulation. It involves not only the internal carotid artery system but also the vertebrobasilar artery system and the external carotid artery system. MSCTA can replace DSA as the preferred method of detecting moyamoya disease.
