摘要

背景：颈动脉分叉处的动脉粥样硬化斑块是缺血性卒中的主要危险因素，缺血性卒中是世界范围内最常见的死亡原因之一，也是致残的主要原因。这项工作的目的：我们研究的目的是确定有症状组和无症状组之间动脉粥样硬化斑块弹性（使用剪切波弹性成像- swe测量）和斑块回声性的差异。方法：58例颈动脉斑块患者纳入我们的研究。测量斑块回声性和以千帕斯卡（kPa）表示的剪切波弹性成像评估。结果：有症状组斑块回声明显减弱，剪切波弹性成像值明显低于无症状组。有症状组斑块杨氏模量（YM）均值为34.23 kPa（千帕斯卡）（SD = 22.3 kPa），无症状组斑块杨氏模量均值为64.84 kPa (35.00 kPa)， P值为：结论：横波弹性成像是量化颈动脉斑块弹性的有效工具，可识别不稳定斑块，有助于患者的合理管理。

Diagnostic value of ultrasound and shear wave elastography in carotid plaque risk stratification.

Background: Atherosclerotic plaque in the carotid bifurcation is a major risk factor for ischemic stroke, one of the most frequent causes of death and a leading cause of disability worldwide.

Aim of this work: The aim of our study was to identify differences in atherosclerotic plaque elasticity (measured using shear wave elastography-SWE) and plaque echogenicity among symptomatic and asymptomatic groups.

Methods: Fifty-eight patients with carotid plaques were enrolled in our study. Plaque echogenicity and shear wave elastography assessments given as kilopascals (kPa), were measured.

Results: Plaques from the symptomatic group were predominantly less echogenic and the shear wave elastography values were significantly lower than those in the asymptomatic group. The mean plaque Young's Modulus (YM) of the symptomatic group was 34.23 kPa (kilo pascal) (SD = 22.3 kPa) compared to 64.84 kPa (SD = 35.00 kPa) in the asymptomatic group with P value of < 0.001.

Conclusion: Shear wave elastography is a helpful tool in quantifying elasticity of the carotid plaques and can help to identify the unstable plaque, which would help in proper patient management.
