What do I need to know about a temporal artery biopsy (TAB)?
TAB is a procedure used to diagnose temporal arteritis. Temporal arteritis, or giant cell arteritis, is damage and inflammation to a certain artery. This artery supplies blood to your head, neck, shoulders, and upper arms. This artery runs along the hairline at the front of your ear and up into your scalp.
How do I prepare for TAB?
Your healthcare provider will talk to you about how to prepare for the biopsy. You may be told not to eat or drink anything after midnight on the day of your procedure. Your provider will tell you which medicines to take or not take on the day of your procedure. Arrange for someone to drive you home and stay with you.
What will happen during TAB?
You will be given local anesthesia to numb the area. With local anesthesia, you may still feel pressure or pushing during the procedure, but you should not feel any pain. A small area of your hair may be cut short to reach your skin. Sterile sheets will be used to cover part of your head for your procedure. Your provider will feel for your temporal artery pulse and make a small incision. Several samples of your artery will be taken and examined. Your provider will use stitches to repair your artery and close your incision. A bandage may be applied to stop any bleeding.
What will happen after TAB?
You may be given an antibiotic cream or pill to prevent infection. Your artery will take several days to completely heal from the procedure. Do not play any sports or do heavy lifting during this time.
What are the risks of TAB?
You may bleed more than expected or develop an infection. Your incision area may heal more slowly than you expect. You may have a scar at the incision site. There is also a rare risk of facial nerve damage after the biopsy.
