Abstract

Normal and abnormal flow waveforms, electromagnetically measured in the reconstructed arteries of patients with peripheral occlusive diseases of the lower extremity, were analyzed in terms of luminal velocity profile, using a newly designed flow wave simulation pump. The blood flow with normal flow wave was characterized by a large fluctuation in the velocity profile in the limited layer adjacent to the wall, where a reversal stream was characteristically noted during the phase of cardiac diastole. In contrast, in the abnormal flow wave, the velocity profile in the limited layer adjacent to the wall was always stagnant with little change in the velocity during each phase of a cardiac cycle. These observations clearly explain why an artery with a normal flow waveform remains patent, while an artery with an abnormal waveform tends to occlude. It was also found that the electromagnetically determined flow waveforms do provide the required information on the luminal velocity distribution.

摘要

利用新设计的血流波模拟泵,从管腔速度剖面的角度,分析了下肢周围闭塞性疾病患者重建动脉中通过电磁测量得到的正常和异常血流波形。具有正常血流波的血流特点是,在紧邻血管壁的有限层内速度剖面有较大波动,其特征是在心脏舒张期出现逆流。相反,在异常血流波中,紧邻血管壁的有限层内的速度剖面在心动周期的每个阶段都始终停滞,速度变化很小。这些观察结果清楚地解释了为什么具有正常血流波形的动脉保持通畅,而具有异常波形的动脉则倾向于闭塞。还发现,通过电磁测定的血流波形确实提供了有关管腔速度分布的所需信息。
