The benefits of installing stents for clogged blood vessels in the feet include: dilating blood vessels, improving local blood circulation, and so on. If the blood vessels in the feet are blocked, most of them are caused by calcification or narrowing of the blood vessels. By putting stents in the feet, the blood vessels can be dilated, the local blood circulation can be improved, the blood vessels can be re-circulated, so that the symptoms of ischemia can be improved, and the ischemia can be avoided to lead to necrosis or even amputation. After stenting, it is also necessary to develop good living habits, with a low-fat and low-salt diet, and increase some soothing exercises (e.g. walking) as appropriate. The need for stenting should be considered according to the patient’s condition.
