| 目的 采用半定量及定量CEUS评价不同血压状态下高血压伴低回声颈动脉斑块患者斑块内微血管灌注程度。方法 对高血压伴低回声颈动脉斑块患者27例监测24 h动态血压，观察其24 h内血压最高值与最低值；比较两种血压状态下斑块增强程度分级及增强强度的差异，并分析收缩压、舒张压与增强强度的相关性。结果 血压最高值与最低值时，低回声斑块增强程度分级差异无统计学意义（Z=0.36，P>0.05），斑块内增强强度差异有统计学意义（t=2.44，P=0.02）。斑块内增强强度与收缩压、舒张压均呈正相关。结论 对高血压伴颈动脉斑块患者进行CEUS时，应考虑血压因素；不同血压状态下，低回声斑块增强强度不同。 |

| Objective To evaluate the degree of microvascular perfusion in hypertension patients with carotid artery hypoechoic plaques with semi-quantitative and quantitative CEUS under different blood pressure conditions. Methods Totally 27 hypertension patients with carotid artery hypoechoic plaques were collected, 24 h ambulatory blood pressure was monitored to observe the highest and lowest blood pressure within 24 h, and the differences of plaque enhancement grade and enhancement intensity were compared between the two blood pressure states. The correlation between systolic blood pressure, diastolic blood pressure and enhancement intensity was analyzed. Results There was no significant difference in the enhancement grade of hypoechoic plaques between the highest and lowest blood pressure (Z=0.36, P>0.05), but there was significant difference of intra-plaque enhancement intensity (t=2.44, P=0.02). The enhancement intensity in plaques was positively correlated with systolic blood pressure and diastolic blood pressure. Conclusion Blood pressure should be taken into account when CEUS of carotid plaques are performed in hypertension patients. The enhancement intensity of hypoechoic plaques is different under different blood pressure conditions. |
