PERIPHERAL ANGIOGRAPHY

A Simple Explanation

This is a medical imaging technique used to visualize the inside of peripheral arteries and identify narrow vessels.

What is it?

Peripheral Angiography is a medical imaging technique that is used to visualize the inside of the peripheral arteries. This procedure is usually done using X-ray based techniques called fluoroscopy and a radio-opaque contrast agent (dye).

The contrast is injected into the peripheral artery through a catheter that is inserted through the groin or arm area and then the X-Ray is used to capture images of the narrowed or blocked areas in the arteries that flow in the legs. Thus indicating the plaque buildup on the inside walls of the peripheral arteries and detect the peripheral vascular disease (PVD).

The term Angiography is defined based on the Projectional Radiography technique, the practice of producing 2D images using X-Ray radiation. But it is applied to the newer CT (Computed Tomography) Angiography and MR (Magnetic Resonance) Angiography.

Peripheral Arteries

The blood vessels, that supply oxygenated blood coming from the heart to the arms, hands, legs and feet of the human body, are called the Peripheral Arteries.

Risks of Peripheral Angiography

  • The damage caused by the catheter
  • Irritation to the skin at the insertion point of the catheter
  • Allergy to the dye that is being used.

When is it needed?

This is usually performed to identify the narrowing of the peripheral arteries in patients with leg cramps, which is caused by the low blood flow down the legs and the feet. This is also done for patients with renal stenosis that can cause high blood pressure. It is also helpful to find and repair stroke. Most of these are done through the femoral artery, but can also be done through the brachial and axillary artery.

The Procedure

Pre-Procedure

  • Please inform the doctor of any allergy to the X-ray contrast dye or to iodine based substances.
  • The patient might be asked to fast without food and water before the angiography.
  • Please inform the doctor of any medications that the patient is presently takin

The Actual Procedure

A catheter is inserted into an artery in the patient’s leg either in the upper thigh or groin area or the arm. Once the catheter is in place, the contrast is injected and released to flow and then the images of the plaque build up are taken using the X-ray technique called Fluoroscopy.

Post-Procedure

  • The patient will be put under observation for a couple of hours.
  • There might be a small bruising at the catheter entry point; it is common and nothing to be worried about.
  • In order to prevent bleeding, the puncture point might have pressure applied. This pressure will be removed after sometime.
  • The patient will be asked not to move the leg, with the catheter site, for a couple of hours.
  • The patient will be checked regularly for bleeding or swelling.
