Why is the doctor performing this test?
- To evaluate the presence of plaque build-up (atherosclerosis) in the
peripheral arteries.
- Peripheral vascular disease, or peripheral artery disease, is caused by
the same atherosclerotic plaque that causes coronary artery disease.
Atherosclerosis, or the build up of plaque, can occur in arteries throughout
the body. Some of the more commonly affected peripheral
areas are the arteries in the legs, arms, kidneys and neck. Some patients may
have both coronary artery disease and peripheral vascular disease.
- As the internal lining of the artery thickens from the atherosclerotic
plaque, the blood vessel becomes increasingly constricted and blood flow
diminishes. Therefore, the symptoms you may experience depend on what artery
is affected and how severely the blood flow is reduced.
- Some of the symptoms you may experience in the affected areas are:
- Claudication (dull, cramping pain in hips, thighs or calf muscle)
- Buttock pain
- Numbness or tingling in leg, foot or toes
- Changes in skin color (pale, bluish or reddish discoloration)
- Changes in skin temperature, coolness
- Impotence
- Infection/sores that do not heal
- Ulceration or gangrene
- Uncontrolled hypertension (high blood pressure)
- Renal (kidney) failure
What is the test?
Peripheral vascular angiography is an invasive diagnostic test using a catheter
to inject dye (contrast medium) into peripheral arteries. X-rays are taken of
the dye within the arteries, allowing clear visualization of the blood flow
inside the artery where peripheral vascular disease occurs. To access the
affected artery, the doctor will thread a catheter to the damaged artery. He or
she will access the site by puncturing the groin (through the femoral artery) or
the arm (through the radial or brachial artery).
Where is the test performed?
In the Heart Hospital Cardiovascular Lab or the Interventional Radiology Suite.
How long does this test take?
Peripheral vascular angiography takes about an hour.
