Peripheral Vascular Angiography
Why
is the doctor performing this test?
To evaluate
the presence of plaque build-up (atherosclerosis) in the peripheral
arteries--meaning the arteries to the lower abdomen, kidneys, arms, legs,
and feet. Plaque build-up in the peripheral arteries causes pain,
especially in the legs with walking (called claudication).
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
Cardiac Catheterization Lab or
the Interventional Radiology Suite.
How
long does this test take?
Peripheral
vascular angiography takes about an hour.
