高频超声对糖尿病颈动脉血管粥样硬化斑块的诊断研究

Diagnosis of Carotid Atherosclerotic Plaque of Diabetes by High Frequency Ultrasound

目的研究高频超声对糖尿病颈动脉血管粥样化(CAS)板块的诊断价值。方法回顾性分析该院2014年1月—2016年1月收治的98例经DSA证实的CAS糖尿病患者的临床资料,所有患者均经高频超声检查。比较超声与DSA诊断结果,分析高频超声声像图特征。结果高频超声诊断轻、中度、重度狭窄及血管闭塞检出率与DSA结果比较差异无统计学意义(P>0.05),高频超声斑块检测率明显高于DSA(P<0.05)。结论高频超声对斑块识别率高,并可鉴别斑块性质,对CAS的诊断有一定指导意义,可用于CAS高危人群筛查,应用前景好。

Objective This paper tries to study the diagnostic value of high frequency ultrasound in diabetic carotid artery atherosclerosis（CAS）. Methods The clinical data of 98 cases of CAS diabetes patients from January 2014 to January 2016 in this hospital tested by DSA were retrospectively analyzed; all patients were examined by high frequency ultrasonography.The diagnostic results of ultrasound and DSA respectively were compared, and the characteristics of high frequency ultrasound image were analyzed. Results There was no significant difference in the detection rate of mild, moderate, severe stenosis and vascular occlusion in high frequency ultrasonography and DSA（P〈0.05）. The common carotid artery detection rate by ultrasonography was higher than that by DSA（P〈0.05）. Conclusion High frequency ultrasound has high recognition rate of plaque, and can identify the plaque nature, which has certain guiding significance for the CAS diagnosis. It can be used for high-risk CAS screening with good application prospects.
