| 目的 研究经颅彩色多普勒超声联合颈动脉血管超声对大脑中动脉(MCA)粥样硬化性脑梗死患者的应用价值。方法 选择75例MCA粥样硬化性脑梗死患者作为观察组、40例门诊正常健康体检者作为对照组,经颅彩色多普勒超声(TCCS)检测双侧MCA收缩期峰值血流速度(Vs)、舒张末期血流速度(Vd)、搏动指数(PI)及阻力指数(RI)；颈动脉血管超声测量双侧颈总动脉(CCA)收缩期血管内径(Ds)、CCA平均内中膜厚度(IMT),观察有无斑块,并记录CCA及颈内动脉(ICA)斑块的回声强度、数目及斑块累及的血管数。结果 脑梗死组CTA双侧CCA-Ds、CCA-IMT均高于对照组(P＜0.05)；脑梗死组双侧MCA-RI、MCA-PI均高于对照组(P＜0.05)；脑梗死组颈动脉斑块发生率、混合回声和低回声斑块发生率、多发斑块发生率高于对照组(P＜0.05)。结论 经颅彩色多普勒超声联合颈动脉血管超声可以协助早期诊断MCA粥样硬化性狭窄。 |

| Objective To analyze the clinical values of TCCS combined with carotid duplex ultrasound on patients with MCA atheroscerosis cerebral infarction.Methods We selected seventy-five patients with MCA atherosclerosis cerebral infarction who were affirmed by CT angiography (CTA) and 40 healthy controls with matched age and gender.The systolic velocity (Vs),the diastolic velocity (Vd),the pulsatility index(PI) and the resistance index (RI) of both sides of MCA were noted with TCCS.The systolic diameter (Ds) of the common carotid artery(CCA),the average of intima-media thickness (IMT) were measured with carotid duplex ultrasound.We watched whether there were plaques,and noted the echo,the number of the plaques and the number of vessels being involved.Results The Ds and IMT of bilateral CCA in the group of patients with cerebral infarction were larger than those in the control group (P＜0.05).The RI and PI of bilateral MCA in the group of patients with cerebral infarction were higher than those in the control group (P＜0.05).The incidence rate of plaques,the checking rate of mixed-echo and lower-echo plaques and the rate of multiple plaques in bilateral CCA in the group of patients with cerebral infarction were higher than those in the control group(P＜0.05).Conclusion TCCS combined with carotid duplex ultrasound can assist in the diagnosis of MCA atheroscerosis stenosis. |
