| 目的 探讨颈动脉狭窄(CAS)患者椎动脉血流动力学改变。方法 对65例住院患者行颈动脉超声检查,测量颈动脉内膜中层厚度(IMT)及椎动脉血流流速,并分析CAS椎动脉血流动力学改变的危险因素。结果 依据颈动脉血管狭窄超声诊断标准分为CAS组21例(32.3%),非颈动脉狭窄组(NCAS)44例(67.7%)。CAS组IMT厚度大于非CAS组(P<0.05),CAS组的双侧椎动脉收缩期峰值流速(PSV)均大于非CAS组(P<0.05),而双侧椎动脉内径及阻力指数之间差异无统计学意义。logistic回归分析显示双侧椎动脉的PSV为CAS的危险因素。结论 CAS引起椎动脉血流动力学变化。 |

| Objective To investigate the changes of hemodynamics of vertebral artery in patients with carotid artery stenosis (CAS).Methods A total of 65 subjects have been enrolled into the study cohort.Carotid intima-media thickness (IMT),and vertebral artery flow velocity were measured by ultrasound.Risk factors of hemodynamics changes in the vertebral artery were identified in patients with CAS.Results According to the ultrasound diagnostic criteria for vascular stenosis,21 cases (32.3%) were classified into CAS group and 44 cases (67.7%) in non-carotid artery stenosis group (NCAS).The IMT in CASs was thicker than that in NCASs (P<0.05).The peak systolic velocities (PSV) of bilateral vertebral arteries in CASs were thicker than that in NCASs (P<0.05).However,there were no significant difference in the diameters and RI between CASs and NCASs.Logistic regression analysis showed that PSVs of vertebral artery were a risk factor for CAS.Conclusion CAS impaires hemodynamics of vertebral artery,and significantly increases blood flow velocity in vertebral artery. |
