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