Discharge Instructions for Cerebral Angiography 

You had a procedure called cerebral angiography. This is an X-ray study of the blood vessels that supply your brain. During the procedure, the healthcare provider put a thin, flexible tube (catheter) into a blood vessel in your groin, arm, or neck through a small cut (incision). The provider injected contrast dye into your bloodstream to help take clear X-ray images. Here’s what to do at home afterward. 

Possible complications to watch for

The most common complication of this test is a blood clot (hematoma) where the catheter was inserted. This is usually in the groin.  A blood clot appears as a lump the size of a tennis ball under the skin.  The medical staff usually notices this before you leave the imaging facility.  A blood clot is treated by putting pressure on the site for a few hours to prevent it from getting bigger.  You will be told to put cold packs on your groin for 24 hours to ease the pain.  It takes a couple of weeks for the blood clot to heal. 

A less common complication is transient ischemic attacks (TIA) or a stroke.  A TIA or stroke is caused by less blood flow to your brain. You might have weakness of an arm or leg, have difficulty speaking and understanding words, or lose some vision or not remember things well.  A TIA can last just a few hours. A stroke can last for days or weeks, or be permanent.  The older you are, the greater the risk for a TIA or a stroke after a cerebral angiography. You might notice these symptoms at the time of the test or after you have left the imaging facility, sometimes days later. 

What to do at home 

  • Rest at home in bed for 12 hours, or as long as directed.

  • Go back to your normal diet and take your regular medicines.

  • Do only light and easy activities for 2 to 3 days.

  • Drink 6 to 8 glasses of water a day. This will keep you from losing fluid. It will also help flush the X-ray dye out of your body.

  • Don't drive until the day after your procedure.

  • Don’t do strenuous activity for 2 weeks. Don’t lift anything heavier than 10 pounds for 3 to 4 days.

  • You can shower the day after your procedure. But don't swim or sit in a bath or hot tub until your incision site has healed.

  • Take your temperature and check your incision site for signs of infection every day for 1 week. Check for redness, swelling, or warmth at the site.

  • Ask your healthcare provider when you can go back to work.
