A brain angiogram (cerebral angiogram) is a test (also called a procedure) that looks for problems with blood vessels and blow flow in the brain. These problems may include a bulge in a blood vessel (aneurysm), a narrowing or blockage of a blood vessel, or bleeding in the brain. The test may be used to check other symptoms, such as unusual headaches, or to check problems found during a different test.
The doctor puts a thin, flexible tube (catheter) into a blood vessel in your groin. Or the doctor may put the catheter in a blood vessel in your arm.
During the procedure, the doctor moves the catheter through the blood vessel into your brain. Then he or she injects a dye into the catheter. The dye flows into the blood vessel. The dye makes the blood vessels show up on a video screen. A picture of the blood vessel in the brain can be seen on a video screen. The doctor can look at the screen to see any problems with the blood vessels or blood flow.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.
