Heart Angioplasty surgery is a procedure used to increase the flow of blood through a narrowed artery. It involves placing a long thin tube (catheter) into a blood vessel to place a small balloon at the site of the narrowing. When the balloon is inflated, the blood vessel should open and allow a healthy flow of blood.
The procedure is done while doctors use an angiogram, a special kind of x-ray image that shows the arteries live on a screen.
Angioplasty is performed when a narrowed artery puts the health of tissues at risk due to the lack of blood supply delivering oxygen. It is sometimes called stent implantation.
It is most commonly used on the arteries that supply blood to heart muscle, to relieve the symptoms of angina or restore blood flow after a heart attack.
Different procedures are used for different conditions:
. Percutaneous coronary intervention (PCI, also called percutaneous transluminal coronary angioplasty, coronary angioplasty or balloon angioplasty): used to open clogged heart arteries
. Cerebral angioplasty (also called craniocervical angioplasty): used to open blood vessels in the head and neck to prevent a stroke
. Angioplasty of the leg: used to prevent pain or allow a wound or ulcer in the leg to heal
. Renal artery angioplasty: used to reduce high blood pressure or keep the kidneys working properly
. Bowel angioplasty: used to reduce abdominal pain
Angioplasty is generally regarded as safe.
Some people have allergic reactions to the dye used in the x-ray procedure or other medications.
On rare occasions blood vessels or nerves are accidentally damaged during the procedure, which can cause long-term problems.
If you have severe pain or bleeding after angioplasty, you should see a doctor without delay.
