What is an angiogram?
An angiogram is an x-ray examination of your arteries (blood vessels). Angiography can be used to look at arteries in the body. A specially trained doctor, known as 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. 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?
There are three major steps to having an angiogram. First, the Catheter insertion . The interventional radiologist will clean the area where the catheter will be inserted. This area is at the top of the leg or on the upper arm. The doctor will then put a local anesthetic in the skin. After that, you will feel pressure when 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. Second, the Contrast injection. 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 will feel hot inside (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. Third, the Catheter removal. 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 stop the artery from bleeding.
How do I prepare for my angiogram?
When you go home:
Take it easy for 24 hours. Drink plenty of fluids. Resume your regular diet. Keep a bandage on the catheter insertion site for a day. Do not drive or run machinery for at least 24 hours. Do not do any strenuous exercise or lifting for at least two days. Do not take a hot bath or shower for at least 12 hours. DO NOT SMOKE FOR AT LEAST 24 HOURS.
Call your doctor immediately if:
You start to bleed where the catheter was inserted. If you start to bleed, lie down flat and apply pressure on the bleeding area. Your doctor will tell you if you need to return to the hospital. There is any change in the color or the temperature of the area where the catheter was inserted. There is numbness, coolness or a change in color of the arm or leg where the catheter was inserted.
After The Procedure
If you are already a patient in the hospital or if you have been scheduled to be admitted to the hospital immediately after your angiogram: you will stay in the hospital after your study is completed. You will return from the radiology department to your hospital room, and the nursing staff will observe you to make sure you are all right. If you are having your angiogram done as an outpatient: you will stay in the hospital for four to six hours after the procedure is completed. Hospital staff will watch over you to make sure that you are all right. You will go home after the observation period. Please make arrangements for someone to drive you home. You may not drive yourself home. The radiologist will send a report to your doctor after he has studied your x-rays. It is best to ask your doctor for the exam results.
