Analysis of flux motion by the laser Doppler technique in the forefoot of healthy controls and patients with peripheral arterial occlusive disease was performed by establishing computerized frequency histograms. It was found that the low frequency components (1-10 cycles/min) are caused by local vasomotion. The prevalence of high frequency flux waves (15-25 cycles/min) is significantly increased in peripheral ischemia compared to normal conditions. After successful reopening of large arteries by angioplasty the prevalence decreases (p less than 0.001). Preliminary results indicate that these high frequency rhythmic fluctuations might by induced by respiration.
通过建立计算机化频率直方图,运用激光多普勒技术对健康对照者和外周动脉闭塞性疾病患者的前足血流运动进行了分析。结果发现,低频成分(1 - 10次/分钟)是由局部血管运动引起的。与正常情况相比,外周缺血时高频血流波(15 - 25次/分钟)的发生率显著增加。通过血管成形术成功重新开通大动脉后,该发生率降低(p小于0.001)。初步结果表明,这些高频节律性波动可能是由呼吸引起的。
