目的探讨成人烟雾病的DSA表现类型。方法回顾性分析33例临床诊断为烟雾病患者的DSA表现,并与现行文献中所定义的血管造影特征表现相比较。结果33例患者的DSA表现有4种类型:①双侧颈内动脉末端及大脑前、中动脉狭窄或闭塞23例,双侧颅底大量血管网形成。②单侧颈内动脉末端闭塞伴基底动脉狭窄或闭塞5例,闭塞处颅底有血管网形成。③单侧颈内动脉末端闭塞伴对侧大脑前、中动脉水平段严重狭窄或闭塞3例,有不同程度颅底血管网形成。④单纯双侧大脑前、中动脉水平段闭塞2例,闭塞处颅底有血管网形成。其中后3种均不符合文献中所定义的烟雾病的特征表现。结论成人烟雾病的DSA表现有多种多样化的表现类型。提议将烟雾病在血管造影上的表现分为典型性和非典型性两类,可以最大程度涵盖烟雾病的血管造影表现。
Objective To explore the DSA manifestations of adult moyamoya disease. Methods Retrospective analysis of DSA findings of 33 clinically diagnosed moyamoya disease patients was performed and compared with the angiographic features defined in the current literature. Results There were 4 types of DSA manifestations in 33 patients: ①the end of bilateral internal carotid artery and 23 cases of stenosis or occlusion of anterior and middle cerebral artery, and the formation of a large number of vascular network in bilateral skull base. ② unilateral end of carotid artery occlusion with basilar artery stenosis or occlusion in 5 cases, the occlusion at the base of the skull vascular network formation. ③ unilateral internal carotid artery occlusion with the contralateral side of the anterior cerebral artery, severe stenosis or occlusion in 3 cases, with varying degrees of intracranial vascular network formation. ④ simple bilateral frontal and middle cerebral artery occlusion in 2 cases, the occlusion at the base of the skull vascular network formation. None of the latter three met the characteristics of moyamoya disease as defined in the literature. Conclusion DSA manifestations of adult moyamoya disease have a variety of manifestations. The proposed moyamoya disease in angiography performance is divided into two types of atypical and atypical, you can maximize the coverage of moyamoya disease angiography performance.
