Angioplasty for Peripheral Arterial Disease of the Legs
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.
In 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.
What To Expect After Treatment
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.
Why It Is Done
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).
How Well It Works
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 of arteries:
Complications related to the catheter include:
Serious complications are rare. These complications may include:
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.
What To Think About
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.
