Angiography is a procedure to look at blood vessels in your body. Angiography can be used to look for narrowing, a blockage, or problems with your blood vessels. It can also be used to check blood flow to organs such as your heart, lungs, or kidneys. Angiography can help your healthcare provider diagnose or treat a medical condition.


Drink liquids as directed:

Liquids will help flush the contrast liquid out of your body. Ask how much liquid to drink after your procedure, and which liquids to drink.


You may need to rest and avoid moving the area where the catheter was inserted. Too much activity may increase your risk for bleeding. Ask your healthcare provider when you can return to normal activities.

  • You have numbness or tingling in an arm or leg.
  • You have questions or concerns about your condition or care.
