Biomechanical behavior of the common femoral artery: Healthy and atherosclerotic artery

ABSTRACT

The elastic modulus of elastic arteries has been extensively studied, while studies of muscular arteries are sparse. In this study, the elastic modulus of right common femoral artery [RCFA] were estimated with the kinetic pressure changes and compared in healthy and atherosclerotic groups. The relative diameter and kinetic pressure changes of the RCFA were measured and estimated using echo-tracking sonography and Doppler spectrum analysis in 41 men [16 healthy and 25 atherosclerosis diseases]. Then the kinetic elastic modulus in the RCFA was estimated in two groups. The results show that, the arterial strain was significantly high in healthy group relative to atherosclerotic group. The estimated values of kinetic elastic modulus of RCFA in atherosclerotic artery are significantly high compared with healthy group [P-value < 0.05]. It is concluded that in RCFA with large content of smooth muscles, mechanical properties [Kinetic elastic modulus] are affected by progression of atherosclerosis
