The accurate localization of hemodynamically significant disease in the aortoiliac segment remains a major clinical dilemma that contributes to the less than optimal results reported for aortofemoral bypass grafting in patients with disabling lower limb claudication. We assessed the hemodynamic status of the aortoiliac segment with direct intraarterial pressure measurements obtained prior to arteriography. This served as a basis for determining the role of the femoral pulsatility index (FPI) in evaluating the hemodynamics of the aortoiliac segment. A stepwise decision making algorithm, developed from the results, enabled accurate identification of the location of the hemodynamic disturbance in 94% of the limbs studied. In 62% of the limbs, the FPI could be used, while in the remaining 38%, intra-arterial pressure measurements were used.
在主髂动脉段对具有血流动力学意义的疾病进行准确定位，仍然是一个主要的临床难题，这导致在患有致残性下肢间歇性跛行的患者中，主动脉股动脉旁路移植术的效果不尽人意。我们通过在动脉造影术前进行直接动脉内压力测量，评估了主髂动脉段的血流动力学状态。这为确定股动脉搏动指数（FPI）在评估主髂动脉段血流动力学中的作用提供了依据。根据结果开发的逐步决策算法，能够在94%的研究肢体中准确识别血流动力学紊乱的位置。在62%的肢体中，可以使用FPI，而在其余38%的肢体中，则使用动脉内压力测量。
