What to tell your healthcare provider before your procedure:

Tell your healthcare provider if you have allergies to any medicines such as contrast liquid, pain medicines, or anesthesia medicine. You may be given contrast liquid during the procedure to help the blood vessels in your liver show up better in pictures. Tell your healthcare provider if you are pregnant or think you are pregnant. X-rays used during the procedure may be harmful to your baby. Your healthcare provider may still do the procedure but decrease the amount of x-rays your baby is exposed to.

Nicotine and other chemicals in cigarettes and cigars can cause lung damage and increase your risk for new or returning cancer.

You may need help doing things in your home, or someone to drive you to errands. Another person should stay with you so he or she can call 911 if you have complications from your procedure. You cannot drive for 24 hours.

What to expect after your procedure:
