A series of 29 femoropopliteal bypass operations is described. The patients were selected carefully to exclude those with clinical and aortographic evidence of aorto-iliac disease. A pulsatility index was calculated from the velocity waveforms recorded over the common femoral and popliteal arteries. The pulsatility index is the ratio of the amplitude of the waveform to its mean height over one cardiac cycle. There was a highly significant difference in the result of the operation between patients with a pulsatility index of 4 or more in the common femoral artery and patients with a pulsatility index of less than 4. We concluded that calculation of this pulsatility index provides useful additional evidence when selecting patients suitable for a femoropopliteal bypass.
本文描述了一系列29例股腘动脉搭桥手术。患者经过仔细挑选，以排除那些有腹主动脉-髂动脉疾病临床和血管造影证据的患者。根据在股总动脉和腘动脉记录的速度波形计算搏动指数。搏动指数是一个心动周期内波形幅度与其平均高度的比值。股总动脉搏动指数为4或更高的患者与搏动指数小于4的患者之间，手术结果存在高度显著差异。我们得出结论，在选择适合股腘动脉搭桥的患者时，计算这种搏动指数可提供有用的额外证据。
