What is percutaneous coronary intervention?
Percutaneous coronary intervention, or PCI, is a technique used to restore and maintain a reasonable blood supply to the heart muscle. The heart muscle is supplied by the so -called coronary arteries that can narrow or defend themselves in certain conditions. During the percutaneous coronary intervention, the surgical balloon is inflated inside the narrowed artery, expansion and improvement of blood flow. In the newly extended section, a tube is called a stent to open. Percutaneous coronary intervention can also be referred to as balloon angioplasty or coronary angioplasty. Angina is a condition where coronary arteries that supply heart muscles do not provide enough blood for the heart to function normally. This usually causes chest pain during exercise. For people whose angina is only mild, PCISSARY does not have to be and the condition can be controlled by drugs. In some cases, coronary artery surgery may be more suitable, where a blood vessel from others in the body is used to circumvent the blocked artery. To the monitor afterThe degree is used by fluoroscopy, technology that provides movable X -ray images. The wire is inserted into the artery into the arm or leg and moved to the tapered coronary artery. This wire is then used to guide the balloon to the position.
Balloon inflation is used to expand the artery at its narrow point, and if the stent was originally slipped through the deflated balloon, it is at the same time extended to the place. In other cases, the stent is placed after the balloon download. Sometimes what is called a cutting balloon, with blades that scored oily plakyna walls of the narrowed arteries. This allows the thickened area to disintegrate and stretch more freely and the balloon can be inflated to lower pressure, but still sufficiently expand the artery.
After percutaneous coronary intervention, most patients experience their condition. In cases where the coronary artery has been completely blocked, the outlook is less certain, with a successful outcome only in at thehalf of the cases. Although percutaneous coronary intervention has a positive result, it is possible for complications to arise later. Inside the stent, blood clots may occasionally form, and it is usually necessary to use aspirin and other medicines to prevent blood or PCI stroke. Sometimes the artery wall around the stent may be recovered in such an extent that it again causes narrowing, which requires a repetition of the original procedure.
