| 目的探讨超声弹性成像(UE)检测应变率比值(SR比值)、剪切波速度(SWV)与颈动脉斑块稳定性的关系及预测脑梗死的价值。 方法106例颈动脉斑块患者根据是否发生脑梗死分为脑梗死组和对照组,根据斑块稳定性分为稳定组和不稳定组。采用UE检测各组SR比值和SWV,分析其与颈动脉斑块稳定性的关系及预测脑梗死的价值。 结果脑梗死组SR比值、SWV低于对照组,不稳定斑块发生率高于对照组(P＜0.05)。不稳定组SR比值、SWV低于稳定组(P＜0.05)。SR比值、SWV与颈动脉斑块稳定性独立相关(P＜0.05)；SR比值、SWV联合诊断颈动脉斑块患者发生脑梗死的效能高于单一参数(P＜0.05)。 结论UE检测SR比值、SWV可客观评价颈动脉斑块稳定性和预测脑梗死发生,为临床完善脑梗死发生风险评估机制提供参考。 |

| To investigate the relationship between strain rate ratio (SR ratio) and shear wave velocity (SWV) detected by ultrasound elastography (UE) and carotid plaque stability and the value of predicting cerebral infarction. Methods106 patients with carotid plaque were divided into cerebral infarction groupand control group according to whether cerebral infarction occurred, and dividedinto stablegroup and unstable group according to plaque stability. The UE test was used to compare the SR ratio and SWV in each group, and to analyze its relationship between carotid plaque stability and the value of predicting cerebral infarction. ResultsThe SR ratio and SWV in the cerebral infarction group were lower than those in the control group, and the incidence of unstable plaque was higher than that in the control group (P＜0.05). SR ratio and SWV were lower in the unstable group thanthose in the stable group (P＜0.05). SR ratio and SWV were independently associated with carotid plaque stability (P＜0.05); the efficacy of combined SR ratio and SWV in diagnosing cerebral infarction in patients with carotid plaque was higher than that of a single parameter (P＜0.05). ConclusionThe SR ratio and SWV detected by UE can objectively evaluate the stability of carotid plaque, and provide a reference for improving the clinical risk assessment mechanism of cerebral infarction. |
