Transcutaneous Measurement of the Elastic Properties of the Human Femoral Artery

摘要: Measurements of human femoral arterial wall properties have been obtained transcutaneously in a group males who were clinically free arteriosclerosis obliterans. The patients divided into three groups according to age: under 35, 35-60, and over 60 years. Diameter changes diameter measured using an ultrasonic echo-tracking system. Arterial pulse pressure was determined by the auscultatory method. results suggest that arteries become stiffer with age. pressure-strain elastic modulus (Ep) varied from 2.6 ± 0.3 sem x 106 dynes/cm2 young 6.3 1.0 old group. These values are similar those reported other investigators invasive vitro technics. Although statistical comparisons indicate significant difference between groups, there considerable variation within groups. Not infrequently, for Ep individuals oldest fell well range
