Angioplasty (also called percutaneous
transluminal angioplasty, or PTA) is a procedure in which a thin, flexible tube
called a catheter is inserted through an artery and guided to the place where
the artery is narrowed.
When the tube reaches the narrowed
artery, a small balloon at the end of the tube inflates for a short time. The pressure from the inflated balloon presses the fat and calcium
(plaque) against the wall of the artery to improve blood flow.
angioplasty of the aorta (the major abdominal artery) or the iliac arteries
(which branch off from the aorta), a small, expandable tube called a
stent is usually put in place at the same time.
Reclosure (restenosis) of the artery is less likely to occur if a stent is
used. Stents are less commonly used in angioplasty of
smaller leg arteries like the femoral, popliteal, or tibial arteries, because they are subject to trauma
and damage in these locations.
After the procedure, you will rest in
bed for 6 to 8 hours. You may have to stay overnight in the hospital. After
you leave the hospital, you can most likely return to normal activities.
This procedure is commonly used to
open narrowed arteries that supply blood flow to the heart. It may be used on
short sections of narrowed arteries in people who have
peripheral arterial disease (PAD).
Angioplasty can help you walk farther without leg pain than you did before the procedure.1
How well angioplasty works depends on the
size of the blood vessel, the length of blood vessel affected, and whether the
blood vessel is completely blocked. In general:
In general, angioplasty works best in the following types
Complications related to the catheter include:
Serious complications are
rare. These complications may
There is always a slight risk of damage to cells or tissues
from being exposed to any radiation, including the low levels of X-ray used for
this test. But the risk of damage from the X-rays is usually very low
compared with the potential benefits of the test.
In some cases, bypass
surgery may be the best treatment choice. This treatment choice depends on your
risks with the procedure, the size of the arteries, and the number and length
of the blockages or narrowing in the arteries.
Angioplasty may be a less
expensive, safer alternative to surgery in certain cases.
