动脉狭窄

Abstract］ Objective To evaluate the role of three-dimensional （3D） digital subtraction angiography in the diagnosis and treatment of symptomatic intracranial arterial stenosis.Methods Stent-assisted angioplasty was performed on 30 patients with symptoms of intracranial artery stenosis by 3-dimesion（3D） method.These imagings were reviewed by different locations to get information of optimal projection angle in 2D angiography.
