If your doctor orders an angiogram, be assured that you are in good hands with Banner Health. Imaging tests, like angiograms, are part of our comprehensive care, helping to make sure there is a complete understanding of your condition so we can provide the best treatment options possible.

What Is an Angiogram?

An angiogram is an x-ray procedure used to detect blockages in the arterial system, typically around the heart. A cerebral angiogram looks at the blood vessels in your neck or head. A CT angiogram (CTA) uses a computed tomography scan (CT scan) to examine your heart and blood vessels. Learn more about CT angiograms.

When Is an Angiogram Used?

Your doctor may order an angiogram if you are experiencing symptoms that may be due to blocked arteries or blockages around your heart. This test can help diagnose a stroke, an aneurysm, tumors, blood clots, and arterial stenosis.

How to Prepare for an Angiogram

The team at Banner Health will let you know how to prepare for your angiogram. Common considerations include:

  • Fasting: You may need to fast 6-8 hours before the procedure
  • Adjusting medication: Some medications should not be taken before certain types of angiograms. Be sure to talk with your doctor before stopping any medication
  • Breastfeeding: If you’re currently breastfeeding, pump before the procedure. Additionally, you should not breastfeed for at least 24 hours after your angiogram

What to Expect from an Angiogram

Angiograms are performed in a hospital setting. Typically, you will be sedated during this procedure. An angiogram procedure may take only 15-20 minutes to perform the angiogram or it could take a couple of hours, depending on your unique medical needs.

An angiogram starts with a needle being inserted into your femoral artery (located in your groin). A catheter is inserted into the area of interest. As a contrast dye is injected, x-ray images are taken to identify blockages. This will help your surgeon decide the best mode of treatment. Some therapies such as a balloon angioplasty and stent replacement can be performed as part of the angiogram or afterwards.

After the procedure, you will need to stay on your back for 6 hours and you’ll want to make arrangements for a family member or friend to drive you home. 

Associated Risks

The risk of side effects from an angiogram is quite low. The most common side effect is bruising or mild tenderness at the insertion site.

Be sure to mention any allergies or additional health conditions you may have and feel free to ask questions at any time before or after your procedure. Our team is here to help at every step.
