烟雾病的MSCTA分析研究

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。

MSCTA Anasysis of Moyamoya Disease Wang

Objective To deepen the understanding of the essence of moyamoya disease. Methods Collect the MSCTA pictures(including the original axial images and VR、MIP、MPR after treatment images)of our hospital’s 30 patients with moyamoya disease,combine cerebral angiography result,documents and materials to analyze. Results All 30 patients showed stenosis and obstruction of internal carotid artery system,including 10 cases with single and 20 cases with bilateral lateral,11 cases with stenosis and obstruction of posterior cerebral artery,20 cases with collateral circulation of posterior cerebral artery and external carotid artery system,11 cases with aneurysm;All cases can observe the abnormal vascular network,Part of the patients examined by DSA,and the results are consistent. Conclusions Moyamoya disease is stenosis and occlusion of cerebral artery,with extensive collateral circulation,it involves not only internal carotid artery system,but also involving the vertebral-basilar artery system and external carotid artery system.MSCTA can replace DSA as moyamoya disease first examination method.
