Patients with intermittent claudication due to stenosis of the arteries of the lower extremity may demonstrate pedal pulses at rest which disappear with exercise. It is believed by some observers that pulses disappear because of arterial spasm.7-9,12 It is believed by others that the decrease in pulsation is due to redistribution of blood flow to the exercising muscle with a relative decrease in distal pulsatile flow.2,5,14

An experimental model was, therefore, designed to study the phenomenon of disappearing pulses. The electromagnetic flow-meter with noncannulating probes provided a method of making direct measurements of flow in the intact canine iliac artery while distal arterial pressures were recorded. The limb was exercised by electrical stimulation of the sciatic nerve after the iliac artery was stenosed to varying degrees.

Sixteen patients with localized areas of stenosis of the femoral or popliteal artery and arterial insufficiency were also studied before and after
