高频彩超在诊断血管性痴呆患者颈动脉粥样硬化斑块中的价值及对诊断率的影响

The value of high frequency color Doppler ultrasound in the diagnosis of carotid atherosclerotic plaque in patients with vascular dementia and its influence on the diagnosis rate

目的探讨高频彩超在诊断血管性痴呆患者颈动脉粥样硬化斑块中的价值及对诊断率的影响。方法选取2018年2月至2020年2月本院接收的血管性痴呆患者53例作为研究组,选取同期进行体检的健康人员53名作为对照组,通过病理诊断对患者病情进行初步确诊后,应用高频彩超对患者进行影像学检查,分析影像结果的诊断率,通过高频超声对患者颈动脉内-中膜厚度(IMT)以及粥样硬化斑块形成状况进行准确探测分析。结果与对照组比较,研究组颈总动脉、颈内动脉以及颈动脉分叉处的IMT增厚程度均较高(P<0.05);研究组敏感度及准确度均明显高于对照组(P<0.05);研究组检出斑块总数45处,对照组检出斑块总数13处,研究组粥样硬化斑块检出率明显较高(P<0.05)。通过斑块分布位置可以发现,颈动脉分叉处斑块数量明显高于颈总动脉及颈内动脉处斑块数量(P<0.05);与对照组比较,研究组所含斑块数量明显较多(P<0.05),且研究组检出斑块中软斑的数量明显高于混合斑及硬斑数量(P<0.05);经高频彩超辅助检查后诊断率得到明显提升(P<0.05)。结论应用高频彩超诊断血管性痴呆患者颈动脉粥样硬化斑块,可以提升诊断率,能明确了解患者疾病的不同状态,有效反映及判断患者的预后及病程进展情况,同时能为疾病后续治疗提供依据,值得临床推广使用。

Objective To investigate the value of high-frequency color ultrasound in the diagnosis of carotid atherosclerotic plaque in patients with vascular dementia and its influence on the diagnosis rate.Methods 53 patients with vascular dementia received in our hospital from February 2018 to February 2020 were selectedt as study group,and select the same period for medical health personnel 53 cases as control group,patients after preliminarily confirmed by pathological diagnosis of disease,patients with application of high frequency colour Doppler ultrasound to exceed to give imaging examination,and the diagnosis rate of image results was analyed,and then by high frequency ultrasound in patients with carotid arteryfilm thickness(IMT)and atherosclerotic plaque formation condition for accurate detection analysis.Results Compared with the control group,IMT thickening degree of common carotid artery,internal carotid artery and bifurcation of carotid artery in the study group was relatively high(P<0.05).The sensitivity and accuracy of the study group were significantly higher than those of the control group(P<0.05).In the study group,the total number of plaque detected was 45,while in the control group,the total number of plaque detected was 13.Compared with the control group,the detection rate of atherosclerotic plaque in the study group was significantly higher(P<0.05).The number of plaques in the bifurcation of carotid artery was significantly higher than that in the common carotid artery and internal carotid artery(P<0.05).Compared with the control group,the number of plaques in the study group was significantly higher(P<0.05),and the number of soft plaques detected in the study group was significantly higher than that of mixed plaques and hard plaques(P<0.05).The diagnosis rate was significantly increased after assisted examination by high frequency color Doppler ultrasound(P<0.05).Conclusion Carotid atherosclerotic plaques in the diagnosis of vascular dementia patients during the application of high frequency colour Doppler ultrasound to exceed can promote diagnostic rate,and the different status of disease in patients with a clear understanding,to the patient's prognosis and progression to reflect and judge effectively,provide detailed basis for follow-up treatment for diseases at the same time,can promote the use.
