Carotid and Peripheral Angiography
Peripheral and carotid angiography are invasive diagnostic procedures that help
visualize the arteries of the neck, arms and legs. They are performed in the catheterization laboratory using
thin plastic tubes (catheters), which are inserted through the groin in most cases. A contrast agent (dye) is injected through
the catheter, and allows imaging of the inside of the artery. This is done under fluoroscopic (X-ray) guidance, and the
procedure is observed on a monitor, similar to a computer monitor.
The purpose of this procedure is to diagnose atherosclerosis (cholesterol
blockages), known as peripheral vascular disease (PVD). This test will determine the extent, severity and location
of the disease, and a decision can be made about the optimal treatment. Treatment may involve medications,
percutaneous intervention (angioplasty and stenting), surgery, or a combination of the above. If a decision is made to proceed with angioplasty and stenting, this may be performed immediately following angiography
or may be delayed for another day. This procedure is very similar to coronary angiography.
