摘要
目的:探讨彩色多普勒超声技术测量椎动脉血流量对后循环缺血(PCI)的诊断价值。方法:选取2012年1月至2013年1月在本院神经内科住院并接受治疗的PCI患者58例作为观察组,另选取同期住院并确诊为非后循环缺血症的患者50例作为对照组。所有患者均接受颈部血管超声检查,测量椎动脉内径及血流量,观察组患者需行头颅CTA检查,比较两组患者的椎动脉内径、血流量及颈动脉硬化斑块发生率等。结果:观察组患者的椎动脉内径及血流量明显低于对照组,两组比较差异有统计学意义(P<0.01);观察组颈动脉硬化斑块的发生率为77.5%(44例),对照组颈动脉硬化斑块的发生率为42%(21例),两组比较差异有统计学意义(P<0.05).无狭窄、轻度狭窄、重度狭窄及闭塞的椎动脉血流量的变化(此处所指的血流量是指小于200 mL/min那部分患者)有明显差异(P<0.05)。结论:与头颅CTA对比检查,彩色多普勒具有直接、准确、方便及可重复性等优点,可有效的诊断后循环缺血症状。
Objective: To measure the blood flow volume of vertebral artery by means of color Doppler ultrasound, and to discuss its values of diagnosing the posterior circulation ischemia (PCI). Methods: Fifty-eight cases who were diagnosed of PCI and treated in the neurology department of our hospital from January 2012 to January 2013 were recruited as the observation group. Another fifty cases without PCI were recruited as the control group at the same time. All the 118 cases were measured the inner diameter and blood flow volume of vertebral artery by ultrasonography. The patients in the observation group were examined with brain CTA. Then we compared the vertebral artery diameter, blood flow and the incidence of carotid atherosclerosis plaque between two groups. Results: The blood flow volume and the inner diameter of the observation group were lower than those of the control group, and there were statistically significant differences between the two groups (P〈0.01). The incidence rates of atherosclerotic plaques in the observation group and control group were respectively 77.5% and 42%, which was significantly higher in the observation group (P〈0.05). Conclusion: Color Doppler ultrasound can offer a direct, faster, noninvasive and more accurate way to diagnosis PCI.
