Angiography - Medical Imaging - St. Michael's Hospital

Programs & Services - Medical Imaging

This is an arterial procedure similar to an angioplasty. A wire mesh device is placed to open up a narrowing in the blood vessel to keep it patent.

This procedure takes about one to two hours.

If you are diabetic, do everything you would normally do. Do not take your metformin. A blood test will be done once you arrive in hospital.
If you are not diabetic, do not have anything to eat or drink after midnight.
If you are taking aspirin, Coumadin, Tyclid, Plavix or Aggrenox please stop taking this medication one week before, but only with your doctor's approval.
Please take all of your medications with a small amount of water, especially heart and blood pressure medications.
If you have had a previous allergic reaction to contrast media (X-ray dye), please inform us and your doctor in advance. Your doctor may order a medication for you to take prior to your procedure.
You will need someone to take you home and stay with you overnight, if there is no other adult at home.
