摘　　要：目的 探讨基底动脉（BA）延长、扭曲对经颅多普勒超声（TCD）检测的BA血流动力学参数的影响。方法 收集行颅脑CT血管成像（CTA）并评价BA延长、扭曲，同时行TCD检查的153例患者纳入本研究。以CTA为诊断标准对BA延长、扭曲进行分级，其中144例有BA延长和/或扭曲，9例无BA延长和/或扭曲。TCD检测的BA血流动力学参数包括收缩期峰值血流速度（PSV）、平均血流速度（MFV）、舒张末期血流速度（EDV）、搏动指数（PI）及阻力指数（RI）。分析BA延长、扭曲分级与TCD检测的BA血流动力学参数之间的关系。结果 ①TCD检测的BA血流动力学参数（PSV、MFV、EDV、PI、RI）在延长分级各组之间无显著统计学差异，且与延长分级之间无显著统计学相关性。②TCD检测的BA血流动力学参数（PSV、MFV、PI、RI）在扭曲分级各组之间有显著统计学差异，两两组间比较，发现BA血流动力学参数（PSV、MFV、PI、RI）在BA扭曲0级与3级之间均有显著统计学差异。BA血流动力学参数（PSV、MFV、EDV、PI、RI）与扭曲分级之间有显著统计学负相关性。结论 BA扭曲明显时可导致脑血流动力学改变，而BA延长对脑血流动力学影响不明显。Objective To investigate the influence of lengthening or tortuous basilar artery （BA） on the BA hemodynamic parameters measured by transcranial doppler （TCD）.Methods 153 cases with CTA and TCD simultaneously evaluating the BA were included. According to CTA criterion, 144 cases were with lengthening and/or tortuous BA and 9 cases were without lengthening and/or tortuous BA.The TCD cerebral hemodynamic parameters included peak systolic velocity （PSV）,mean blood flow velocity （MFV）, end diastolic velocity （EDV） , pulsatility index （PI） and resistant index （RI）. The relationship between the grading of lengthening/tortuous of BA and TCD parameters were analyzed. Results ① The TCD parameters (PSV, MFV, EDV, PI, RI） showed no significant statistical differences among the grades of lengthening BA. The correlation between the TCD paremeters （PSV, MFV, EDV, PI, RI） and the grades of lengthening BA showed no significant statistical differences.②The TCD parameters （PSV, MFV, PI, RI） showed significant statistical differences among the grades of tortuous BA. The TCD parameters （PSV, MFV, PI, RI） showed significant statistical differences between grade 0 and grade 3 of tortuous BA. The significant negative correlation between the TCD parameters （PSV, MFV,EDV,PI,RI） and the grades of tortuous BA was found.Conclusion The tortuosity of BA can lead to hemodynamic alterations, whereas the lengthening of BA does not affect cerebral hemodynamics significantly.
