Careful use of the data from the vascular laboratory has resulted in better patient and operation selectivity in peripheral arterial disease of the lower extremities. Using the combination of segmental pressure measured with an ultrasonic Doppler and flow as approximated by the measurement of the rate of pulsatile volume change with a calibrated plethysmograph, objective criteria were established for arterial insufficiency. Using a two cuff technique, resistance indices were established to distinguish femoropopliteal from aortoiliac disease. The ratio of angiograms to femoropopliteal and aortoiliac operations has been reduced from an earlier value of almost 3/1 to the present value of approximately 1/1.
对血管实验室数据的谨慎使用，已在下肢外周动脉疾病中实现了更好的患者和手术选择。通过结合使用超声多普勒测量的节段性压力以及用校准体积描记器测量搏动性容积变化率估算的血流，建立了动脉供血不足的客观标准。采用双袖带技术，建立了阻力指数以区分股腘动脉疾病和主髂动脉疾病。血管造影与股腘动脉及主髂动脉手术的比例已从早期几乎3/1的数值降至目前约1/1的数值。
