According to the curent state of science, artery diseases are caused by an inflammatory process within the artery wall. The inflammation process leads to the degeneration and ultimately to the calcification of the blood vessel, medically referred to as arteriosclerosis. In addition to nicotine, an increased cholesterol level and diabetes mellitus are ensured as risk factors. Arteries can develop an expanding (dilatative) form of arteriosclerosis. Such dilated forms are known as aneurysms and affects approximately five percent of the population over 65 years of age. However, narrowing or occlosing forms of arteriosclerosis are more common. Vascular occlusions can occur in every artery, however certain sites are more preferred than others. Example of such are: the coronary arteries (heart), carotid arteries (neck) and femoral arteries (leg). In the case of vessal constrictions of femoral arteries complaints can arise, which are referred to in common language as ‘smoker’s leg’.
