摘　　要：目的探讨吸烟对血流动力学的改变及对脑血管的影响。方法采用经颅多普勒超声技术对200例吸烟者颅底动脉血流速度及脉动指数进行了检测,同时对频谱形态进行动态观察。结果吸烟对颅底动脉血流速度有明显改变(P<0.01);吸烟对脉动指数(PI值)有不同程度的影响(P<0.05);吸烟时间的长短与频谱形态的改变成正相关。结论吸烟是引起血流动力学改变的重要因素之一,杜绝吸烟对于减慢动脉硬化,减少脑血管病的发生有重要意义。Objective The aim of the present study was to investigate the effects of smoking on hemodynamics changes and cerebrovessels. Methods Transcranial Doppler ultrasonography was employed to examine the blood flow rates of cerebral basilar arteries and pulsatility indices. Frequency spectrum was also observed and analyzed dynamically. Results The blood flow rates of cerebral basilar arteries were significantly changed with smoking (P<0.01). Pulsatility indices were also affected to different extents with smok...
