What Is Angiography?

Angiography techAn angiography, or angiogram, is an X-ray exam of the arteries and veins used to diagnose problems with the blood vessels, such as a blockage or narrowing.

Angiograms can be used to diagnose:

  • Aneurysms, which are bulges or balloons in a blood vessel
  • Cerebrovascular disease, such as stroke or bleeding in the brain
  • Blood vessel malformations

During the angiogram, an interventional radiologist inserts a thin catheter into the artery through a small nick in the skin. An X-ray dye called a contrast agent is injected to make the blood vessels visible on the X-ray.

If the doctor sees that there is a blockage or narrowing in a blood vessel that could interfere with the normal flow of blood, he can treat the blocked blood vessel without surgery during the aniogram.

The blocked or narrow blood vessels can be treated with:

What to Expect
Prior to appointments, Gwinnett Medical Center patients are asked to come in for routine lab work. It is preferred that patients have their lab work performed at Gwinnett Medical Center so the radiology nurses have access to the results. Our radiology nurses call each patient shortly after the procedure is scheduled to obtain a health history and provide instructions.

For most interventional radiology exams, patients need to arrive in admissions two hours before their scheduled procedure time on the day of the exam. Patients will check in at admissions before being taken to the Imaging Nursing Unit, where an interventional radiologist will come to talk with the patient before the procedure. The patient will then be prepped for the exam and taken to the Interventional Radiology Suite for the procedure. Following the procedure, the patient will return to the Imaging Nursing Unit for recovery. The recovery time varies based on the procedure. After the patient is then discharged, he or she will receive a follow-up call the next day.
