目的研究彩色多普勒超声对老年脑梗死患者颈部动脉斑块的诊断价值。方法选取50例老年脑梗死患者作为观察组,选取同期50例老年健康体检者作为对照组,两组均接受彩色多普勒超声检查,对其诊断结果进行对比。结果观察组共检出49例(108块)斑块,斑块的检出率为98%(49/50);其中溃疡斑35例,硬斑15例,软斑55例,扁平斑3例;对照组患者共检出10例(60块)斑块,斑块的检出率为20%(10/50);其中溃疡斑10例,硬斑30例,软斑2例,扁平斑18例。观察组的斑块检出率显著高于对照组(P<0.05)。溃疡斑以及软斑为观察组的主要形态,硬斑与扁平斑为对照组的主要形态;颈总动脉分叉处为斑块发生的主要部位,其次为颈总动脉起始部。观察组左侧颈总动脉内中膜厚度为(1.06±0.22)mm,右侧颈总动脉内中膜厚度为(1.05±0.25)mm,显著大于对照组的(0.75±0.14)、(0.74±0.12)mm,差异有统计学意义(P<0.05)。结论彩色多普勒超声对老年脑梗死患者颈部动脉斑块的诊断价值显著,具有良好的推广价值。
Objective To study the diagnostic value of color Doppler ultrasound in the diagnosis of cervical artery plaque in elderly patients with cerebral infarction. Methods Fifty elderly patients with cerebral infarction were selected as the observation group and 50 elderly healthy subjects were selected as the control group. Both groups received color Doppler ultrasonography and their diagnostic results were compared. Results In the observation group, 49 cases (108 blocks) were detected, and the detection rate was 98% (49/50). There were 35 cases of ulcer, 15 cases of hard spot, 55 cases of soft spot and 3 cases of flat plaque ; The control group of patients were detected in 10 cases (60 blocks), the detection rate of plaques was 20% (10/50); ulcer in 10 cases, 30 cases of hard spot, 2 cases of soft plaque, flat plaque 18 example. The detection rate of plaque in the observation group was significantly higher than that in the control group (P <0.05). The main forms of ulcer plaque and soft plaque were the observation group, and the plaque and flat plaque were the main forms of the control group. The common carotid bifurcation was the main site of plaque formation, followed by the common carotid artery. (1.06 ± 0.22) mm in the left common carotid artery and 1.09 ± 0.25 mm in the right common carotid artery were significantly higher in the observation group than those in the control group (0.75 ± 0.14 and 0.74 ± 0.12) mm, the difference was statistically significant (P <0.05). Conclusion Color Doppler ultrasound in the diagnosis of cervical artery plaque in elderly patients with cerebral infarction significant value, with good promotional value.
