DEFINITION

It is an intense muscular pain, which appears in the legs at level of the calf or of the thigh, during a walk or after a light physical exercise and that disappears on having stopped.

CAUSES

The pain takes place for the absence of oxigenaci&o¾ of the muscles involved in the effort to walk, since due to a tightening of the arteries that contribute blood to the legs (iliacas, femorales, and tibiales). The obstruction is produced by the presence of badges of ateroma, what we call arterioesclerosis.

The arterioesclerosis is like an aging of the arteries that become rigid, in a progressive process that consists of the accumulation of cholesterol, calcium and other fats in the wall of the arteries. In certain areas of the arteries the punctual tightening is more intense, going so far as to cover almost completely the blood step. On having needed the legs, more bleed during the effort, this one cannot come and the pain of the muscles appears in the intermittent submission.

COMPLICATIONS

If in the area obstructed by badges of ateroma thrombocytes accumulations stick, they go so far as to form clots (thrombi). If this area catches fire and diverse thrombi appear it is named a thrombosis. These thrombi they can release (embolism), and for his size they come to smaller arteries for which they cannot happen, stop up it completely and produce what is called the sharp isquemia. This situation is very serious since it can evolve to the death of the textiles involved in the isquemia and the irreversible loss of the same ones.

TREATMENT

The best treatment is to dry off surgically the artery involved in the obstruction by badges of ateroma and in his place synthetic materials place an arterial prosthesis. This intervention is realized under general anesthesia, by means of an abdominal incision.

Another method that can be applied is the angioplastia transluminal percutánea. This intervention consists of the dilation of the artery affected by the badge of ateroma, by means of the introduction of a catater across the skin, up to the artery of question. The catater takes a balloon in his end that swells up and deflates several times up to obtaining a good blood circulation across the artery.
