Moyamoya病数字减影血管造影的诊断价值

Diagnostic value of the digital subtraction angiography in moyamoya disease

目的 评价数字减影血管造影 (DSA)对Moyamoya病分期诊断的价值。方法 对 31例患者的DSA检查进行了回顾性分析。结果 31例DSA显示不同程度的颈内动脉分叉处血管狭窄或闭塞以及侧支循环 ;并根据Suzuki分期对 31例患者 5 7个大脑半球病变进行了分期 :属于Ⅰ期病变者有 4个大脑半球 ,Ⅱ期 10个 ,Ⅲ期 17个 ,Ⅳ期 12个 ,Ⅴ期 6个和Ⅵ期 8个。结论 DSA可清晰显示Moyamoya病血管狭窄的程度、闭塞部位及侧支循环的情况 ,并作出分期 。

Objective To evaluate the value of DSA in the diagnosis of staging moyamoya disease (MMD).Methods DSA of 31 patients with MMD were reviewed retrospectively. Results The stenosis or occlusion with different extents of the supracranial internal carotid arteries and the collateral circulations were shown in DSA of the all patients. MMD lesions of 57 cerebral hemispheres shown in the DSA of 31 patients were diagnosed by staging according to the description of Suzuki: Stage Ⅰ in 4 cerebral hemispheres; Ⅱ,10;Ⅲ17;Ⅳ12;Ⅴ6 and Ⅵ,8. Conclusions DSA could show clearly the stenotic degree, occlusive site and collateral circulation of the MMD and simultaneously with the staging of the disease; and thus guiding the choice for early surgical teatment.
