MEDICATED BALLOON ANGIOPLASTY VERSUS PLAIN OLD BALLOON ANGIOPLASTY FOR IN-STENT RESTENOSIS IN LOWER LIMB ARTERIES

The endovascular method that is based on dilating a stenotic or obstructed artery is called angioplasty, which is carried out with the purpose of restoring the blood flow that is blocked, for which we must emphasize that this problem can have multiple etiologies. This technique is performed by means of a catheter through an artery, until the affected artery is located, then a guide is inserted through the catheter that passes through the diseased vessel, fixing it at the end of the occlusion, thus placing a balloon in said arterial segment, which will be inflated as many times as possible and necessary to achieve a better blood flow, therefore a stent is implanted. However, it is essential to mention the famous "in-stent restenosis" since this occurs when the stent located in the occluded artery causes stenosis again, that is, it causes a narrowing again in the area that was affected or obstructed. Stent occlusions can be fixed in a number of ways, such as balloon procedure to break up the formed clot or placing another stent in the damaged area.
