[The relationship between the surface of the peripheral volume pulse and the segmental blood flow]

It is reported on 65 patients, out of whom in 48 cases angiographically proved vascular obstructions in the pelvic and femoral regions were present. The comparison of the plethysmographic area calculated and the values of the blood supply established in the same segment of extremities resulted in a good correlation. The area of the peripheral volume pulse gives references to the compensation degree of a vascular obstruction. Slighter sclerotic vascular changes already cause a significant decrease of the area of the volume pulse, so that this method of evaluation seems to be suitable for the early recognition of the arteriosclerosis in the area of extremities.
