摘要
目的探讨老年良性阵发性位置性眩晕(BPPV)患者椎动脉血流的高频超声特点及其临床意义。方法选取110例健康志愿者(对照组)及120例BPPV发作期老年患者(BBPV组),采用彩色高频多普勒超声观察患者的椎动脉椎间段(V2段),记录其管腔内径、收缩期峰值流速(PSV)、舒张末期血流速度(EDV)及阻力指数(RI)。结果与对照组比较,BPPV组椎动脉椎间段内径减小,PSV、EDV降低,RI升高(均P<0.05)。结论老年BPPV患者的椎动脉管腔纤细,血容量下降,彩色高频超声技术对诊断老年BPPV具有重要意义。
Objective To explore the high-frequency ultrasound features of vertebral artery blood flow in the elderly patients with benign paroxysmal positional vertigo（BBPV） and its clinical significance. Methods A total of 110 healthy volunteers and 120 elderly patients with acute BPPV were selected as control group and BBPV group respectively. High-frequency color Doppler ultrasound was used to observe the intervertebral segment（V2） of the vertebral artery,then related parameters were recorded including internal diameter of lumen,peak systolic velocity（PSV）,end diastolic velocity（EDV） and resistance index（RI）. Results Compared with the control group,the internal diameter of the intervertebral segment,PSV and EDV decreased and RI increased in the BPPV group（all P〈0. 05）.Conclusion Narrow lumen of the vertebral artery and decreased blood flow can be found in the elderly patients with BBPV. And high-frequency color ultrasound is significant for the diagnosis of elderly BBPV.
