Atherosclerosis is the formation of fat plaques in the arteries that lose elasticity and make it difficult for blood to pass through. These plaques are known as atheromas. The process of fat accumulation begins in childhood, but the clinical consequences of the problem manifest later.
Atheromas may rupture, causing acute occlusion due to coagulation in the artery. This condition is associated with the occurrence of heart attack, stroke and lower limb lameness when affecting the legs.
