What is a Peripheral Arteriogram?
Peripheral Arteriogram is an invasive test to determine whether or not there is peripheral arterial disease (PAD), or atherosclerosis of the arteries of the neck, chest, arms, abdomen, kidneys, and/or legs. Atherosclerosis occurs when the artery is damaged. Plaque builds up in the damaged artery, decreasing the flow of blood to the tissues. The location of the plaque determines the symptoms you might have, although some people have no symptoms at all. The symptoms suggest where the stenosis is located, and common symptoms of PAD include impotence, claudication, pain/numbness, in the arms or legs may indicate blockage in the peripheral circulation to the hands or feet. Poorly controlled hypertension, abnormal kidney function can indicate renal artery stenosis. Temporary blindness, weakness in the arms/legs on one side of the body, or slurred speech can indicate blockage in the cerebrovascular circulation to the brain. The results of the angiogram will provide information to your doctor to help determine the next step in your care, which may be risk factor modification, medical treatment (with drug therapy), percutaneous vascular intervention (PVI), and/or surgery.
How the test is performed:
Prior to the procedure, lab work and an ECG may be
performed. You will have an intravenous needle (IV) placed
in your arm or hand. You will be placed flat on the catheterization
table. The nurse or technician will shave and wash your groin (or arm)
to reduce the risk of infection. You may receive some medication
to help you relax, but you will not be given general anesthesia.
Your vital signs will be monitored throughout the procedures. A
local anesthetic (numbing medicine) will be injected where the sheath
(a short tube) will be inserted. You may feel a brief
burning or stinging sensation during the injection, but then you should
not have any further pain. The doctor will then place a catheter
(a long, narrow tube) through the sheath and into the arteries being
evaluated. Once the catheter is in place, contrast (x-ray dye) is
injected and x-rays are taken as the contrast passes through the
arteries. This helps the doctor to see the blockage.
How to prepare for the test:
High-risk patients (e.g., those with diabetes, kidney disease) may be
admitted to the hospital the night before the procedure to receive
intravenous hydration and a steroid to lower the risk for
complications. Do not eat or drink anything 4 hour before the
procedure. You may take your medications, with a small sip of
water. Do not take your insulin or other diabetic medications
prior to the procedure. Please take all of your medications to
the hospital with you, or an exact list of the medications, doses, and
times you take them. Please be certain to tell us if you have any
allergies to drugs or to contrast (x-ray dye). The catheterization can take 30 minutes to an hour. Please have your
family remain in the waiting room during the procedure. Be aware that
the hospital and your doctor provide care for emergency
situations. Although we make every effort to perform your
procedure on time, it is possible that some delays may occur.
How the test will feel:
You will be awake and able to follow instructions during the procedure.
You may feel some discomfort at the site where the IV is placed. Local anesthesia will be used to numb the site, so the only sensation should be one of pressure at the site. You may experience some discomfort from having to remain still for a long time.
Once the procedure is completed, the sheath is removed by a nurse or technician. Pressure is applied to the puncture site, usually in the right groin. Patients should not drive for 2 days, and should not lift anything more than 10 pounds for 5 days after the procedure. Call your doctor for any pain, swelling, bleeding, or fever post-procedure.
