Clinical significance of CTA in diagnosis of carotid artery stenosis

Objective To discuss clinical significance of of CTA in diagnosis of carotid artery stenosis. Methods Retrospective analyzed clinical data of 40 cases with cerebral ischemic disease were detected by CTA and DSA. Clinical significance of CTA in diagnosis of carotid artery stenosis was analyzed. Results Amomg 80 vasculars, patients with unilateral disorder were 9 cases, patients with lateral disorder were 31 cases, and 71 vasculars showed disorder. 16 vasculars showed mild stenosis, 21 vasculars showed moderate stenosis, 31 vasculars showed severe stenosis, and 3 vasculars showed block. CTA showed 118 plaques. 35 plaques were vulnerable, 18 plaques were fibrous, 51 plaques were mixed, and 14 plaques were calcified. Conclusion Carotid artery CTA possesses noninvasive, high resolution, omni-directional imaging, and shows important clinical significance in diagnosis of carotid artery stenosis and clinical efficacy assessment.
