It is a surgical procedure where a balloon is inserted into an artery, which dilates it since it is partially or totally narrow and its primary objective is to regularly increase its diameter, helping at the same time to increased blood flow.

A diseased artery presents obstruction when the endothelial glands form in a layer that covers the inside of the artery, also when it is filled with fatty or cholesterol plaques, with a blood clot or the arterial wall is dilated or filled with blood. . It is a procedure that is carried out with a special type of catheter, which has a small balloon at its tip, which in turn is covered by a mesh called a Stent, which helps correct the narrowing of the coronary arteries or veins of anywhere in the body, the stent is inserted folded and inflated, covering the plaque or opening the obstruction when it expands, then the balloon is removed, leaving the mesh in place, keeping the ductus arteriosus open and with a healthy and constant blood flow.

This procedure is performed depending on the type, characteristics and degree of risk of the patient and the obstruction of the arteries that it presents as the place in the body, that is, not all patients are qualified to perform it. Every surgical procedure has some risks that must be taken into account before performing it, which can damage other blood vessels and can lead to bleeding where the catheter and stent are inserted, in some cases there is a rejection of the product called contrast that is used in the operation to be able to visualize the arteries while the procedure is being carried out, causing apparent damage to the kidneys, arrhythmias are presented and emergency intervention can be performed to place a coronary bypass, since it can become obstructed more the artery to clear it in its entirety, heart attacks or cerebrovascular accidents occur, among others. All of these risks are between a 3-5% chance of occurring in a patient.
