This procedure finds areas in your blood vessels where they are narrowing or closing. An aortogram may also be used to evaluate an abdominal aneurysm.

The doctor will thread a narrow, flexible plastic tube, called a catheter, through the arteries suspected of having the narrowing or blockage. The tube will be hooked to a pump that injects X-ray dye. Once the X-ray pictures show where the blockages are, your doctor will be able to tell the best way to open the blocked blood vessels. This should stop the pain and reduce the risk of blood clots.
