Angiography
Uses of Angiography
Angiography is used to check for abnormalities in blood vessels, usually arteries. Abnormalities may include Blockages Narrowing Abnormal connections between arteries and veins (arteriovenous malformations) Inflammation ( Overview of Vasculitis ) Bulges ( Aneurysms of Arteries in the Arms, Legs, and Heart ) in a weakened blood vessel wall Tears ( Aortic Dissection ) in a blood vessel wall During angiography, procedures to treat the abnormalities detected can sometimes be done: Narrowed arteries can be widened. Blockages can be removed. A tube made of wire mesh (stent) can be placed to keep an artery open. Tears or weakened areas in a blood vessel can be repaired. Blood flow to tumors or arteriovenous malformations can be blocked.
