Vascular arteriography (or angiography) is a type of diagnostic test that is used to
determine if there are blockages in any of the arteries in your body. This test is able to pinpoint the location and
severity of these blockages. It is often used to assess blood flow to your legs, arms, brain, and kidneys, and sometimes
to look for blood vessel aneurysms.
Vascular arteriography is performed by inserting a needle and then a small flexible tube called a catheter into an
artery, usually in the groin area. The doctor gently guides this catheter by X-ray through the artery to the area of
possible blockage. A dye that can be seen by X-ray is injected through the catheter, and pictures are taken and later
studied by your doctor. It is important to tell your doctor or X-ray technologist if you have any allergies to X-ray dye.
Sometimes there is a feeling of warmth or flushing when the dye is injected. This is normal and quickly passes. You will
be given medication to help you relax and lay quietly while the test is being done.
Vascular arteriography is performed by an interventional
radiologist and X-ray technologist.
Your condition during the test is monitored by your radiologist
and a registered nurse.
The procedure usually takes about 45 minutes to an hour to complete.
After the procedure, you will be asked to lay flat for approximately
four to six hours in the recovery area. If your doctor orders
vascular arteriography for you, you will receive specific information
and instructions when the test is scheduled. In addition, the
radiologist will discuss the results of the procedure and possible
appropriate treatments.
