目的探讨急性脑卒中患者颈动脉粥样硬化斑块的超声形态学表现以及探讨不同超声形态学表现的诊断价值。方法对所有入选受检者进行多层螺旋CT或磁共振(MRI)检查、常规颈动脉超声检查、彩色多普勒血流显像(CDFI)、超声造影技术(CEUS)的影像学资料进行回顾性分析;所入选病例组患者在发病2天内完成上述影像学检查,对照组受检者也在2天内完成上述影像学检查。结果常规超声发现病例组颈动脉斑块45处、对照组11处;CDFI发现病例组颈动脉斑块远端血流频谱改变35例、对照组11例;超声造影发现颈动脉斑粥样硬化斑块处毛细血管现象病例组15例、对照组2例。斑块表面形态以及内部回声分布情况两项结果与对照组比较差异有统计学意义。结论脑卒中患者与无症状颈动脉硬化受检者的斑块超声声像图中,斑块表面形态以及内部回声分布两项指标具有明显的鉴别诊断意义。提示表面不光整、内部回声分布不均匀的斑块导致急性脑卒中的可能性较大。
Objective To investigate the ultrasonographic features of carotid atherosclerotic plaque in patients with acute stroke and to explore the diagnostic value of different ultrasonic morphological findings. Methods All selected subjects underwent multi-slice spiral CT or magnetic resonance (MRI) examination, conventional carotid ultrasound examination, color Doppler flow imaging (CDFI) and contrast-enhanced ultrasound (CEUS) imaging data The patients in the selected cases completed the imaging examination within 2 days after the onset of disease. The subjects in the control group also completed the above imaging examination within 2 days. Results There were 45 cases of carotid plaque and 11 cases of control group by routine ultrasound. In the case group, 35 cases of carotid artery plaque were detected by CDFI and 11 cases of control group. Contrast - enhanced ultrasound was used to detect carotid plaque atherosclerotic plaques Block capillaries in 15 cases, control group 2 cases. Plaque surface morphology and internal echo distribution two results compared with the control group, the difference was statistically significant. Conclusions The plaque surface morphology and internal echo distribution in stroke patients and asymptomatic carotid atherosclerotic plaque ultrasound images have obvious differential diagnostic significance. Suggesting that the surface is not smooth, the uneven distribution of internal echogenic patches lead to acute stroke is more likely.
