Frequently Asked Questions about Cerebral Angiography

Cerebral angiography is a type of medical test that’s minimally invasive. The examiner makes use of an x-ray along with iodine which contains contrast material. These items help produce pictures of the brain’s blood vessels. During this procedure, the examiner inserts a catheter into one of the arteries in your arm or leg. It goes through a tiny incision in your skin. Through the guidance of the x-ray machine, the examiner will navigate the catheter all the way to the area to examine. Once it’s there, the examiner injects the contrast material through the tube. Finally, they will capture the images using the ionizing radiation.

What are the types of cerebral angiography?

There are two main types of cerebral angiography. The first procedure involves the insertion of a catheter into one of the blood vessels in the arm or groin. The examiner then guides the catheter to the part of your brain they will examine. Then the examiner will use x-rays to create the angiogram or the vessel’s picture. Then the dye or contrast gets injected to come up with the images of the brain’s blood vessels. There’s also the procedure that’s noninvasive. This involves an MRI (magnetic resonance imaging) or a CT (computed tomography) to come up with the angiogram.

Frequently Asked Questions about Cerebral Angiography

What will you feel after the cerebral angiography?

As mentioned previously, you may feel a slight pinch when the doctor inserts the IV line into your vein. You may also contact something when the examiner injects the local anesthetic. The arteries don’t have any sensation; you’d only feel it in the skin’s incision site. After completion of the procedure, the examiner will take out the catheter.

After the procedure, you may resume your regular diet right away. Then after about 12 hours, you can also continue all of your normal activities.

The examiner may have to monitor you for about 4-6 hours before sending you home. But if you had a noninvasive method, the examiner may send you back right away. If you received sedatives, then you can only get discharged when you’re completely alert, have stable vital signs, and you’re breathing correctly.
