CT Aortogram


A CT Aortogram is performed to study the structure, shape, and functioning of the aorta, which is the largest artery in the human body.

What is CT Aortogram?

CT Aortogram is a diagnostic test that allows the cardiologists to view the functioning of the aorta. The test is performed after injecting a dye into the aorta, which gives a clear view of the blood flow through the artery. The CT Aortogram is performed in a cardiac catheterization lab.

How is CT Aortogram Performed?

CT Aortogram is done at a hospital. The procedure of the test includes:

  • The patient is given a sedative.
  • The radiologist or the cardiologist performing CT Aortogram will insert a needle in the arm or groin area.
  • A catheter is inserted in the aorta.
  • Using x-rays, the catheter is moved to the desired position in the aorta.
  • After the catheter is placed correctly, the dye is injected, and x-ray images are taken to see the movement of dye through the aorta.

After the procedure of CT Aortogram, the catheter is removed, and the patient is kept under observation.

Side-effects of CT Aortogram
CT Aortogram is a complicated procedure. The side-effects of the procedure include:
● Allergy to the dye.
● Bruising at the site.
● Excessive bleeding from the site of catheter insertion.
● Infection.
● Damage to the kidneys due to the dye.
● A blood clot at the catheter insertion site, which travels to the lungs.

Preparation for CT Aortogram

CT Aortogram requires hospitalisation. The preparation for the procedure involves:

  • Discussing medical records and health conditions with the cardiologist.
  • Pre-scheduling the test.
  • Abstaining from eating and drinking 6 to 8 hours before the CT Aortogram test.

Post-care after CT Aortogram

CT Aortogram is a lengthy procedure, which requires hospitalisation for a day. The post-care for the test involves:

  • Patient has to stay in the hospital on the day of the scan.
  • Follow the instructions of the cardiologist regarding medication.
  • Pay close attention to symptoms of allergy or discomfort.
