Peripheral stent implant: solution for the lack of blood supply

A peripheral stent implant is a prosthesis that is placed inside arteries to restore blood flow to the affected organ (usually lower limb) by lack of blood supply. The material that is made is an alloy, nitinol or steel.

There are two main types of peripheral stent implant:

• The expandable balloon, is not suitable for arteries located in areas of stent movement.
• The self-expanding stent is more flexible but has less radial force.

Other types of peripheral stent coated drug as more sophisticated manufacturing inhibiting intimal hyperplasia caused by the stent. Another less common type is the coated ePTFE generally used for aneurysmal disease or trauma.

When peripheral stent implant performed?

This type of treatment is performed when the arteries are narrowed or oblieradas. It is mainly used in peripheral artery disease, which causes chronic ischemia. Chronic ischemia caused by arterial occlusion can manifest itself in various degrees, from pain when the patient walks, the so-called intermittent claudication to limb gangrene.

The implantation technique of a peripheral stent is minimally invasive as it avoids having to subject the patient to open surgery (bypass). It is usually performed under local anesthesia and the entire procedure is performed through a puncture of the artery from which will carry out the catheterization.

Benefits peripheral stent implant

The main consequence of implementing a peripheral stent, is that blood flow in the artery to the affected organ or member is restored. This causes a cessation of symptoms as it returns to get oxygenated blood to the tissue.

In cases where an injury has occurred ischemia, the technique allows the healing of the wound thus avoiding the terrible consequences that could occur if the limb is not revascularized; as it could be the loss of the affected lower limb.
