【摘要】：目的通过运用3D超声断层成像技术评价冠心病患者股动脉斑块的特点,探讨股动脉斑块3D超声断层成像标识与冠心病关系,及该技术评价斑块稳定性的临床应用价值。方法 58例存在股动脉斑块且厚度2.0mm患者,根据诊断结果分为正常组和冠心病组。对斑块行3D超声断层成像,并对三维图像按照统一的标准进行处理,记录斑块的体积、内部回声、形态、位置、横截面积狭窄率,及联合Adobe Photoshop软件获取斑块灰阶值中位数(GSM)、低灰阶值(68)(PLGS)所占比例,所有参数进行两组间的对比分析。结果冠心病组股动脉斑块的GSM低于正常组、而PLGS高于正常组,差异有统计学意义(P0.05);与正常组相比,冠心病组股动脉斑块的内部回声多表现为不均质回声,形态多表现为不规则甚至溃疡等;而两组间的斑块体积、横截面积狭窄率差异无统计学意义(P0.05)。结论 (1)利用3D超声断层成像检测冠心病患者股动脉斑块的特点为GSM低、PLGS高,及多表现为内部回声不均、形态不规则甚至溃疡。(2)3D超声断层成像可以多断面检测股动脉斑块,是一种更客观检测斑块的有效手段,通过对斑块回声的定性、定量诊断,有望为冠心病提供预警。
[Abstract]:Objective to evaluate the characteristics of femoral artery plaque in patients with coronary artery disease by using 3D ultrasound tomography, and to explore the relationship between 3D ultrasound tomography and coronary artery disease. Methods 58 patients with femoral artery plaques with thickness 2.0mm were divided into normal group and coronary heart disease group according to the diagnostic results. The three-dimensional images were processed according to the unified standard, and the volume, internal echo, shape, location, cross sectional area stenosis rate of plaque were recorded, and the proportion of plaque grayscale median value and low gray scale value was obtained by Adobe Photoshop software. Results the GSM of femoral artery plaque in coronary heart disease group was lower than that of normal group, but PLGS was higher than that of normal group, the difference was statistically significant (P 0.05). In coronary heart disease group, the internal echo of femoral artery plaque was mostly uneven, and the shape was irregular or even ulcerated, while the plaque volume between the two groups, There was no significant difference in cross sectional area stenosis rate (P 0.05). Conclusion the characteristics of femoral artery plaque in patients with coronary heart disease by 3D ultrasound tomography are that GSM is low and PLGS is high, and the internal echo is uneven. Irregular and even ulcers 3D ultrasound tomography can be used to detect the plaque of femoral artery on multiple sections. It is an effective method to detect plaque objectively. It is expected to provide early warning for coronary heart disease by qualitative and quantitative diagnosis of plaque echo.
