Coronary Angioplasty

VASCULAR SURGERY – EURODOCTOR.RU – 2007

The method of angioplasty is narrowed to the point that the portion of the artery is fed a special catheter with a balloon inflated at the end. This method is widely used in the treatment of coronary heart disease, chronic obstruction of arteries, narrowing of the carotid, renal arteries, etc.
Coronary Angioplasty (or percutaneous transluminal coronary angioplasty) was first performed by Andreas Gryuntsigom. The technique of angioplasty immediately found its followers, and has been modified by many surgeons. By the mid-1980s, many of the leading cardiac centers have adopted this method as an alternative to bypass surgery. Very often, angioplasty combined with this method, as stenting.
The cause of coronary heart disease, as well as many other ischemic diseases – a narrowing of the arteries, caused mainly by the appearance of the inner wall of the artery build-up special – atherosclerotic plaques. Other causes narrowing of the lumen of the artery may be a violation of the structure of the muscle membrane in a certain section of the artery

Who shows the angioplasty?

When the use of cardiac medications, or lifestyle are not able to sufficiently reduce the manifestations of coronary heart disease, or you have a heart attack, you may be offered angioplasty. Before the angioplasty is usually performed X-ray examination of the vessels of the heart (called coronary angiography – an x-ray method for determining the state of the lumen of the vessels of the heart).
Angioplasty shows the following categories of patients:

  • Low level of narrowing of the vessel
  • You have access to the site of narrowing of the vessel during angioplasty
  • The restriction is not in the main artery of the heart, which brings in the left side of the heart
  • The absence of heart failure

If there is narrowing of the main arteries of the heart, which brings in the left side of the heart, either there or concomitant heart failure, or the small arteries are narrowed, then the best alternative to coronary bypass surgery is considered. This method is also indicated if the patient has diabetes or if the plural is marked narrowing of blood vessels.

Preparing for angioplasty

Before the surgery, angioplasty, the patient is a complete examination. Are electrocardiogram, chest X-rays and blood tests and urine tests. Usually, before the surgery recommended by the famine. Be sure to consult a doctor. If you are taking any medication, especially when it comes to antidiabetic agents.

Angioplasty Procedure

  • As with the stenting, balloon catheter to the narrowed section of artery is fed through the femoral artery. Access to the femoral artery during angioplasty by using a special needle "introducer." Often such a procedure is called percutaneous angioplasty.
  • Once the introducer is in the femoral artery, its stylet (inner part) is removed.
  • Through the lumen of the introducer into the artery gently introduce long flexible plastic tube, called a "catheter-wire." The tip of the catheter is brought to the mouth of the coronary arteries. With the help of a catheter, guide can also carry out a so-called intraoperative coronary angiography. This allows us to identify the exact location of the stage and place of narrowing of the arteries.
  • On the basis of intraoperative coronary heart surgeon assesses the size of the artery and selects the appropriate type of balloon catheter and a guide. In order to thin the blood and prevent blood clots assigned heparin.
  • Explorer Bar is a very thin wire with a radiopaque tip, which is a catheter-wire is introduced into the affected coronary artery. Getting the picture in real time, the surgeon directs the vehicle to the place of constriction, while its tip is to place restrictions.
  • Now the conductor serves as a guidebook to the place of constriction of the artery. At this stage, is introduced into the artery balloon catheter. He has an empty tip, which is able to inflate. Catheter with inflated balloon is introduced into the artery for a place restrictions,
  • After the balloon catheter is inflated it, thus crushing atherosclerotic plaque and widening the artery.
  • If the cartridge when the operation is set stent, the latter as it is pushed into the artery wall and allow it to shrink again.
  • Complications of angioplasty

    Complications of this procedure are similar to those in the stenting.

    • Allergic reactions to radiopaque substance
    • Bleeding at the site of catheter
    • Damage to heart valve or coronary artery
    • Renal failure
    • Irregular heartbeat
    • Insult

    The results of angioplasty

    In most patients, angioplasty greatly improves blood flow in coronary arteries. It greatly reduces the need for coronary artery bypass surgery. I should say that she does not treat the cause of angioplasty with coronary heart disease. Subsequently, the patient may again appear symptoms of the disease. Therefore, it is first necessary to follow a diet, quit smoking and reduce stress.

    The postoperative period after angioplasty

    The patient is usually within two days in office. Six hours after angioplasty, the patient can already walk. Complete recovery occurs within a week.
