目的探讨彩色多普勒超声联合颈动脉血管超声对动脉粥样硬化性脑梗死患者的应用价值,为动脉粥样硬化性脑梗死的有效检查提供依据。方法选取2014年3月—2016年12月南阳医学高等专科学校第一附属医院收治的36例动脉粥样硬化性脑梗死患者设为研究组,另选取同期体检健康者36例设为对照组。所有受检者均接受颈动脉血管超声及彩色多普勒超声检查,统计对比两组颈总动脉收缩期内径(Ds)、内中膜厚度(IMT)、收缩期血流速度峰值(Vs)、舒张末期血流速度(Vd)、阻力指数(RI)、搏动指数(PI),分析颈动脉血管超声、彩色多普勒超声单独诊断及联合诊断脑梗死敏感度、特异度、准确度。结果研究组Ds、IMT、RI、PI水平均高于对照组水平,Vs、Vd水平低于对照组水平,差异有统计学意义(P<0.05);联合诊断敏感度(97.22%)、准确度(93.06%)高于颈动脉血管超声(75.00%、80.56%)、彩色多普勒超声(69.44%、76.39%),差异有统计学意义(P<0.05),联合诊断特异度(88.89%)与颈动脉血管超声(86.11%)、彩色多普勒超声(83.33%)比较,差异无统计学意义(P>0.05)。结论联合颈动脉血管超声及彩色多普勒超声可有效检查动脉粥样硬化性脑梗死患者动脉狭窄,敏感度及准确度高。
Objective To explore the value of color Doppler ultrasound combined with carotid artery ultrasound in patients with atherosclerotic cerebral infarction and to provide evidence for the effective examination of atherosclerotic cerebral infarction. Methods From March 2014 to December 2016, 36 patients with atherosclerotic cerebral infarction admitted to the First Affiliated Hospital of Nanyang Medical College were enrolled as study group, and 36 healthy subjects were selected as the control group. All the subjects underwent carotid artery ultrasonography and color Doppler ultrasonography. The systolic diameter (Ds), intima-media thickness (IMT), peak systolic velocity (Vs) End-diastolic flow velocity (Vd), resistance index (RI), pulsatility index (PI), analysis of carotid artery ultrasound, color Doppler ultrasound alone diagnosis and combined diagnosis of cerebral infarction sensitivity, specificity and accuracy. Results The levels of Ds, IMT, RI and PI in the study group were significantly higher than those in the control group, while the levels of Vs and Vd were lower than those in the control group (P <0.05). The combined diagnostic sensitivity (97.22%), accuracy (93.06%) was higher than that of carotid artery (75.00%, 80.56%), color Doppler ultrasound was 69.44% (76.39%), the difference was statistically significant (P <0.05) Compared with carotid artery ultrasound (86.11%), color Doppler ultrasound (83.33%), the difference was not statistically significant (P> 0.05). Conclusion Combined carotid artery ultrasound and color Doppler ultrasound can effectively detect arterial stenosis in patients with atherosclerotic cerebral infarction with high sensitivity and accuracy.
