Results of Experimental Tests With Arterial Stenosis

David H. Finley, MD; David B. Pilcher, MD

Arch Surg. 1978;113(8):936-939.

Abstract
• A simple, inexpensive pulse wave recording device was tested in large (25- to 40-kg) dogs. Femoral arterial flow, prestenotic and poststenotic arterial waveforms, and pressures were monitored as stenosis was induced with a constricting silk loop. The recording device tested was placed around the distal leg.

The pulse wave recorder accurately reproduced the arterial pulse waveform. The amplitude of the device's waveform was linearly proportional to the arterial pulse pressure. The instrument was sensitive in detecting a flow-limiting stenosis.

The cuff represents an advance in noninvasive vascular assessment because it is quite inexpensive, portable, and durable, as well as precise and sensitive.
