Angioplasty (Stent Implantation)

Stent implantation with Balloon Angioplasty.

Quick facts about Angioplasty

  • Angioplasty is a non-invasive (keyhole) surgical procedure to increase blood flow through an artery.

  • It’s recommended when a narrowed artery is putting your heath at risk. 

  • A small balloon (catheter) is inflated where the blood vessel is narrowed or blocked to opens the artery and allow blood to flow again naturally.

  • Angioplasty is done using a CT coronary angiogram.

  • The entire procedure usually takes 30-60 minutes. 

About angioplasty 

  • Angioplasty is a procedure to increase blood flow through an artery.

  • A small balloon (catheter) is inserted where the blood vessel is narrowed or blocked.

  • When the balloon is inflated, the blood vessel opens and allows blood to flow again naturally.

  • Angioplasty is done using a CT coronary angiogram, a special kind of x-ray that shows the arteries live on a screen.

Why you need it  

  • We perform angioplasty when a narrowed artery is putting your heath at risk, that is, when tissues are affected by the lack of oxygen.

  • Angioplasty is most commonly performed on the arteries that supply blood to the heart – the coronary arteries – either to relieve symptoms of angina or restore healthy blood flow after a heart attack.

  • Other areas treated by angioplasty include the renal artery to the kidney, the carotid arteries in the neck and arteries to the legs.

What’s involved

  • Before angioplasty surgery, you’ll be given full information about any preparation needed. For example, you might need to stop taking certain medicines that can thin the blood and cause bleeding.

  • During the procedure, you’ll be given a sedative to help you relax, then local anaesthetic in the skin near an artery, usually in the groin. We use a special dye with the angiogram (x-ray) that shows up on the screen. This dye is injected into the artery after the anaesthetic.  

  • For the angioplasty, we insert a thin wire into the artery to guide a small tube with the balloon catheter to the narrowing.

  • The balloon is then inflated to stretch the artery before being removed. For an artery supplying the heart, we place a stent – a small wire mesh tube – into the artery to help keep it open after the procedure. 

  • The entire procedure usually takes 30-60 minutes. 

Your recovery

  •  After your surgery, you may need to stay in hospital overnight, sometimes longer if it was an emergency angioplasty.

  • You’ll need to like flat for several hours after the procedure. 

  • There may be some pain or bruising at the insertion site, or discomfort around the stent.

  • Most people quickly go back to their normal (moderate) activity. 

Risks of angioplasty

  • There are risks with any surgical procedure but angioplasty is generally regarded as safe. 

  • Some people have allergic reactions to the dye used but we will discuss all the risks beforehand to ensure you are comfortable with going ahead with the surgery.
