The structural-and-functional changes in the leg triceps of patients with obliterating involvement of the lower limb arteries

The study of some parameters of the structure of m. gastrocnemius and m. soleus has been performed in comparison with their functional status in 42 patients with obliterating involvement of the lower limb arteries using ultrasonography. It has been determined that the structural-and-functional changes in the leg triceps of patients with obliterating involvement of the lower limb arteries depend on the stage of peripheral circulation insufficiency. At the stage of circulation compensated disorder the ultrasonography picture of muscular image is differed from the normal one by the degree of image sharpness only, and in case of decompensation gross pathological changes are noted both in structure and function. The signs of structure homogenization and muscular function loss are more marked for obliterating atherosclerosis.
