目的：用CT血管造影技术（CT angiography,CTA）分析2型糖尿病患者颈动脉粥样硬化斑块特征。方法：纳入我院2021年1月-2022年12月期间住院治疗的2型糖尿病患者62例（观察组）及血糖水平正常患者63例（对照组），所有患者均行头颈CTA检查，比较两组患者颈动脉斑块检出率、颈动脉斑块性质、斑块表面形态及管腔狭窄程度。结果：CTA上显示观察组颈动脉斑块检出率为74.19%，高于对照组53.97%；观察组脂质斑块的发生率较对照组高；观察组不规则斑块及溃疡斑块所占比例高于对照组，光滑斑块所占比例低于对照组；差异均有统计学意义（P<0.05）。结论：2型糖尿病患者颈动脉粥样硬化斑块检出率高，且斑块稳定性差。CTA能分析颈动脉斑块性质、观察斑块表面形态，判断斑块的稳定性，为临床诊疗提供一定依据。

Objective: To analyze the characteristics of carotid atherosclerotic plaque in patients with type 2 diabetes by CT angiography(CTA). Methods: A total of 62 patients with type 2 diabetes mellitus(observation group) and 63 patients with normal blood glucose level(control group) who were hospitalized in our hospital from January 2021 to December 2022 were included. All patients underwent head and neck CTA examination. The detection rate of carotid plaque, the nature of carotid plaque, the surface morphology of plaque and the degree of lumen stenosis were compared between the two groups. Results: The detection rate of carotid plaque in the observation group was 74.19%, which was higher than that in the control group 53.97%. The incidence of lipid plaque in the observation group was higher than that in the control group. The proportion of irregular plaque and ulcer plaque in the observation group was higher than that in the control group, and the proportion of smooth plaque was lower than that in the control group. The differences were statistically significant(P<0.05). Conclusion: The detection rate of carotid atherosclerotic plaque in patients with type 2 diabetes mellitus is high and the plaque stability is poor. CTA can analyze the characteristics of carotid plaque, observe the surface morphology of plaque, and judge the stability of plaque, which provides a certain basis for clinical diagnosis and treatment.
