Peripheral Angiogram

A peripheral angiogram is a diagnostic procedure utilized to evaluate obstructions in the arteries that deliver blood to the legs and feet as well as the arms and hands. These arteries are referred to as peripheral arteries, as they transport blood away from the heart to the body’s extremities. This examination helps in detecting narrowed, obstructed or compromised arteries that could be responsible for symptoms such as leg pain, numbness, or inadequate circulation.

Your doctor will usually perform the test if they suspect peripheral artery disease (PAD), a condition in which plaque buildup limits blood flow to the limbs.

Why is peripheral angiogram done?

A peripheral angiogram is recommended if a patient has:

  • Leg pain or cramping (claudication) that worsens with activity and improves with rest.
  • Non-healing wounds or ulcers on the feet or legs due to poor circulation.
  • Coldness or discoloration in the extremities.
  • Numbness, tingling, or weakness in the legs or arms.
  • Kidney artery disease, which can lead to high blood pressure and kidney problems.

Preparing for a peripheral angiography

It is generally advised that you refrain from consuming food or beverages for approximately six to eight hours prior to your angiogram. Inform your healthcare provider about all dietary supplements, over the counter medications, prescription drugs, and vitamins you are currently taking, as you may be required to discontinue one or more of these prior to the procedure.

Additionally, it is important to notify your provider if you are pregnant or have any of the following conditions:

  • A history of bleeding disorders
  • Allergies, particularly to contrast dye, iodine, latex, or any medications

It is recommended that you arrange for a friend or family member to drive you home following your test.

How does peripheral angiography work?

A peripheral angiography is performed while the patient is positioned on an X-ray table. The physician will apply a numbing agent to the groin or arm and make a small incision. A small rubber sheath will then be inserted into the blood vessel, followed by the introduction of a thin tube known as a catheter. Subsequently, contrast dye will be injected through the catheter and X-ray images will be captured. Afterward, the catheter and rubber sheath will be removed and a bandage will be applied to the incision site. Pressure will be applied to the area and the patient will be required to remain lying down for up to eight hours. The entire procedure typically lasts between 30 to 40 minutes.

In some cases, the physician may perform an additional minor procedure during the same visit as the angiogram. They may assess the arteries and opt to provide immediate treatment. This treatment could involve a peripheral angioplasty, in which a balloon is inflated to displace plaque and enlarge the artery. Alternatively, a stent may be placed, which is a permanent mesh coil designed to keep the artery open against its walls.

Possible Findings

  • Normal blood flow (no blockages).
  • Narrowed arteries due to plaque buildup.
  • Complete blockages preventing blood from reaching certain areas.
  • Aneurysms (weakened, bulging arteries that may rupture).
