What is an angiogram?
An angiogram, also called an arteriogram, is an x-ray examination of your arteries (blood vessels). Angiography can be used to look at arteries in the body. An interventional radiologist performs the angiogram. During the procedure, the interventional radiologist places a catheter or small tube into one of your arteries and injects contrast material (commonly called "dye") into vessel while taking x-rays of the area.

Where is the exam performed? How long does it take?
The arteriogram is performed in the Radiology Department on the B1 level of University Hospital, or on the fourth floor of the CVC (Cardiovascular Center). The angiogram takes about one to two hours to finish. Sometimes, it may take longer. In other cases, the interventional radiologist will do a second procedure, such as an angioplasty, at the same time as the angiogram. This makes the procedure take longer.

What is an angiogram like?
You will be given intravenous sedation. The interventional radiologist will clean the area where the catheter will be inserted. This area is at the top of the leg or rarely on the upper arm. The doctor will then put a local anesthetic in the skin. The catheter is inserted into the artery in the numbed area. The catheter is then guided through the body to the artery that is being studied by watching it on an x-ray screen (similar to a TV screen). You will not feel the catheter moving through your arteries. When the catheter is positioned correctly, contrast (x-ray dye) will be injected through the catheter while X-ray pictures are taken. When the contrast is injected, you may feel warm (this lasts for only a few seconds). In many cases, several contrast injections and several sets of X-rays are needed to complete an examination. After the examination is completed, the interventional radiologist will remove the catheter from the artery. Removing the catheter does not hurt. Pressure will be applied to the area where the catheter was for 10 to 20 minutes. This pressure is to prevent the artery from bleeding.
