目的

应用基于三维超声(3D-US)的灰阶中位数(GSM)定量评估急性缺血性脑梗死患者颈动脉斑块的易损性。

方法

选取2015年12月至2016年8月在陆军总医院就诊且存在颈动脉斑块的患者207例,其中急性缺血性脑梗死患者102例(脑梗死组),非脑梗死患者105例(对照组)。应用血管斑块定量分析(VPQ)软件自动获取颈动脉斑块的GSM值。脑梗死组与对照组患者性别构成、吸烟、饮酒、糖尿病史及高血压病史等一般资料比较采用χ2检验,脑梗死组与对照组患者颈动脉斑块GSM值、厚度、面积狭窄率及体积等超声参数比较采用独立样本t检验。

结果

脑梗死组患者颈动脉斑块的GSM测值显著低于对照组,差异有统计学意义(44.78±11.58 vs 54.36±11.99,t=7.70,P<0.01),脑梗死组患者的低密度脂蛋白显著低于对照组,差异有统计学意义[(3.51±1.20)mmol/L vs(3.10±1.07)mmol/L,t=1.58,P<0.05];2组患者的年龄、性别构成、体重指数、吸烟、饮酒、糖尿病史、高血压病史、收缩压、舒张压、三酰甘油,总胆固醇,高密度脂蛋白、斑块厚度、斑块面积狭窄率及斑块体积比较,差异均无统计学意义(P均>0.05)。

结论

基于3D-US-VPQ技术的颈动脉斑块参数GSM值能有效地反映颈动脉斑块的易损性,在临床颈动脉斑块风险评估中具有一定参考价值。

Objective

To quantitatively evaluate the vulnerability of carotid plaques in patients with acute ischemic cerebral infarction by using Gray-scale median (GSM) based on Three-dimensional ultrasound (3D-US).

Methods

Totally 207 patients were examined with carotid plaques in the PLA Army General Hospital from December 2015 to August 2016, including 102 patients with acute cerebralischemic stroke (cerebral infarction group) and 105 patients without cerebral infarction (control group). The Vascular plaque quantification (VPQ) software was applied to acquire GSM value of carotid plaques automatically.

Results

The GSM value of carotid plaques in cerebral infarction group was significantly lower than that in control group (44.78±11.58 vs 54.36±11.99, t=7.70, P<0.01), and the low density lipoprotein in the cerebral infarction group was significantly higher than that in the control group [(3.51±1.20) mmol/L vs (3.10±1.07) mmol/L, t=1.58, P<0.05]. There was no significant difference between the two groups in age, gender, body mass index, smoking, drinking, history of diabetes, history of hypertension, systolic blood pressure, diastolic blood pressure, triglyceride, total cholesterol, high density lipoprotein, plaque thickness, plaque area stenosis rate and plaque volume (all P>0.05).

Conclusion

The GSM value of carotid plaques based on 3D-US-VPQ technology can effectively reflect the vulnerability of carotid plaques, and may be valuable in the risk assessment of carotid plaques.
