摘要
探讨彩色多普勒超声在急性前循环脑梗死患者颈动脉粥样硬化狭窄程度评估中的临床价值。方法将89例急性前循环脑梗死患者设为研究组,87名健康体检者设为对照组,均行彩色多普勒超声检查,比较两组颈动脉粥样硬化狭窄程度、内-中膜增厚及斑块形成情况,比较两组血流参数。结果研究组颈动脉粥样硬化狭窄检出率显著高于对照组(P<0.01)。研究组颈动脉内-中膜增厚、强回声斑块、混合回声斑块及低/等回声斑块检出率均显著高于对照组(P<0.05或0.01)。两组颈总动脉搏动指数显著比较差异无统计学意义(P>0.05),研究组颈内动脉搏动指数显著高于对照组(P<0.01),研究组颈内动脉及颈总动脉收缩早期加速时间、舒张末期流速、峰值流速显著低于对照组(P<0.01),阻力指数显著高于对照组(P<0.01)。结论彩色多普勒超声可从颈动脉血流动力学及形态学改变反映出颈动脉粥样硬化狭窄程度,对急性前循环脑梗死病因判断、及早预防及预后评估均有重要临床价值。
Objective To investigate the clinical value of color Doppler ultrasound in the evaluation of carotid atherosclerotic stenosis in patients with acute anterior circulation cerebral infarction. Methods 89 patients with acute anterior circulation cerebral infarction were selected as the study group, and 87 patients with non-cerebral infarction were selected as the control group. Color Doppler ultrasonography was performed in both groups. Compare the carotid atherosclerotic stenosis degree, intima-media thickening and plaque formation of the groups. And the blood flow parameters of the two groups were compared. Results The detection rate of carotid atherosclerotic stenosis in the study group was significantly higher than that in the control group (P<0. 01). The carotid artery intima-media thickening, strong echo plaque, mixed echo placjue and low/equal echo plaque detection rate were significantly higher in the study group than those in the control group (P<0. 05 or 0. 01). There was no significant difference in the puLsation index of the common carotid artery between the two groups (P>0. 05). The pulsation index of the internal carotid artery in the study group was higher than that in the control group (P<0. 01). The early acceleration time, end-diastolic flow rate and peak flow rate of the internal carotid artery and common carotid artery in the vStudy group were significantly lower than those in the control group (P<0. 01),the resistance index was significantly higher than that in the control group (P<0. 01). Conclusion Color Doppler ultrasound can reflect the degree of carotid atherosclerotic stenosis from carotid hemodynamics and morphological changes. It has important clinical value for the etiology, early prevention and prognosis evaluation of acute anterior circulation cerebral infarction.
