颈部CTA在颈动脉狭窄诊断中的应用价值

Clinical significance of CTA in diagnosis of carotid artery stenosis

目的探讨颈部CTA在颈动脉狭窄性疾病诊断中的临床价值。方法回顾性分析缺血性脑卒中患者40例的临床资料,所有患者均行DSA检查以及颈部CTA检查,分析其在术前诊断中的应用效果。结果共观察80支血管,其中单侧病变9例,双侧病变31例,共观察到有71支血管发生病变。其中轻度狭窄16支,中度狭窄21支,重度狭窄31支,闭塞3支。CTA观察到118处斑块,其中易损型斑块35处,纤维斑18处,混合斑块51处,钙化斑块14处。结论颈动脉CTA具有无创、高分辨率、全方位成像等优点,在颈动脉狭窄的早期诊断和术后疗效判断中具有重要的临床意义。

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 u- nilateral disorder were 9 cases, patients with lateral disorder were 31 cases, and 71 vasculars showed disorder. 16 vas- culars showed mild stenosis, 21 vasculars showed moderate stenosis, 31 vasculars showed severe stenosis, and 3 vas- culars 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-di- rectional imaging, and shows important clinical significance in diagnosis of carotid artery stenosis and clinical efficacy assessment.
