Angioplasty is the technique of mechanically expanding arteries that are usually narrowed or blocked as a result of atherosclerosis. It is a method of opening vessels by dilating blocked or narrowed vessels with balloon catheters (angioplasty) and placing a special prosthesis, i.e. a stent, in the vein without the need for surgery. If the vessels are blocked or narrowed, a treatment method called angioplasty shall be applied.
This is a treatment that is used if the arteries are blocked or narrowed. The most common disease that causes blockage is atherosclerosis, which is the stiffness of the arteries (arteriosclerosis). In this disease, the fat deposits called plaque form on the inside of the vessel. When the structural features of the inner wall of the arteries are impaired, the vessel stiffens, the vessel thickens, the fat accumulates and the plaque forms cause the vessel to narrow.
