Abstract:
Objective To summarize the initial application of three dimensional angiography(3D angio) in the diagnosis of carotid stenosis and carotid stenting.Methods 23 patients with carotid stenosis confirmed by conventional angiography (two dimensional angiography, 2D Angio) received 3D Angio including 16 accepted both 2D Angio and 3D Angio before and after carotid stenting and then undengone comparative study. Results 32 stenosed lesions were found, including 5 in common carotid artery, 19 in neck section of internal carotid artery, 3 in patrous section, 2 in caverous sinus and 3 in middle cerebral artery. 3D Angio could demonstrate the changes of stenosed segment from every point of view. The degree and extent of stenosis could be accuratly evaluated. The characterization of lesions including the diminution of lumen and coarse plaques could be clearly displayed. After stenting, the wall of stenosed segment became smooth and the plaques disappeared.Conclusions The diagnosis and treatment of carotid stenosis by 3D Angio is helpful to accurately estimate the extent of stenosis, the characterization of the lesions and monitor the results of stenting.
