A brain angiogram (cerebral angiogram) is a test (also called a procedure) that looks for problems with blood vessels and blood 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 catheter may be put in a blood vessel in your arm.
During the procedure, the doctor moves the catheter through the blood vessel into your brain. Then the doctor 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.
Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.
