What are the risks of angiography?
Overall, complications related to angiography are rare. The most common of these is bleeding at the puncture site. At the completion of the exam pressure is applied to the puncture site to keep it from bleeding but some may occur despite this. This is not generally dangerous but may leave the patient with a temporary bruise and lump (clotted blood) at the puncture site. This will resolve on it’s own. Blockage of an artery due angiography is very rare.
