CT Angiogram Of Thoracic Aorta

A CT Angiogram of the Thoracic Aorta is a diagnostic medical test that combines a CT scan with an injection of a contrast material to produce pictures of the thoracic aorta and its branches. The thoracic aorta is the largest artery in the chest and it carries oxygenated blood from the heart to the rest of the body.

This procedure helps to visualize and evaluate the thoracic aorta for aneurysms, dissections, or other pathologies. It is particularly helpful in assessing aortic aneurysms and planning for surgical or endovascular intervention. The procedure also provides information about the size, shape, and condition of the thoracic aorta and can detect inflammation or other changes in its walls.The CT Angiogram of Thoracic Aorta is often recommended to monitor patients with known aortic disease, those who have family history of aortic disease, and patients with certain genetic disorders that affect the connective tissue and can lead to aneurysms.

Specific Instructions:

• Fasting : In most cases, patients are advised to fast for several hours before the test, usually overnight.

• Allergies : It is crucial to inform your doctor about any allergies, especially to contrast materials or iodine. An allergic reaction to the contrast material can cause itching, a rash, or more serious reactions.

• Medications : Inform your doctor of all medications you are taking, as certain medications may need to be stopped before the procedure.

• Hydration : It is usually advised to drink plenty of water the day before the test to help clear the contrast material from your body after the test.

• Pregnancy : If you are pregnant or suspect you might be, you must inform your doctor. Although the radiation exposure from this test is minimal, any radiation exposure during pregnancy should be avoided if possible.

• Kidney function : If you have known issues with your kidneys, let your doctor know. The contrast material could potentially harm your kidneys, especially if their function is already compromised.

What should I expect during a CT Angiogram of the Thoracic Aorta?

You will lie on a narrow table that slides into the center of the CT scanner. Once you are inside the scanner, the machine's x-ray beam rotates around you. You may hear buzzing, clicking and whirring noises during the scan, which are normal.

Is the procedure painful?

The CT scan is not painful, but you may feel discomfort when the intravenous line is placed into your vein for the contrast material. You may also feel warm or flushed when the contrast material is injected.

How long does the procedure take?

The actual scanning portion of the test usually lasts less than 15 minutes. However, the entire procedure, from preparation to completion, usually takes about an hour.

What will happen after the procedure?

After the procedure, you can return to your normal daily activities. You may be instructed to drink plenty of fluids to help your kidneys remove the contrast material from your body.

How will I receive the results of my test?

Your test results will be interpreted by a radiologist and shared with your doctor, who will discuss them with you.

How often should this test be performed?

The frequency of this test will depend on your specific condition. If you have a known aortic disease, your doctor may recommend regular CT angiograms to monitor your condition.

What should I do if I have an allergic reaction to the contrast material?

If you experience any symptoms of an allergic reaction, such as difficulty breathing, hives, or a swollen face or throat, seek immediate medical attention.

What are the risks of a CT Angiogram of the Thoracic Aorta?

Possible risks include an allergic reaction to the contrast material, kidney damage, and radiation exposure. It's important to discuss these risks with your doctor prior to the procedure.

Which doctor should I consult if there are abnormal findings?

A cardiologist or a cardiovascular surgeon will be consulted if there are abnormal findings on a CT angiogram of the thoracic aorta.

Are there any factors that can affect the results?

Certain factors, such as patient movement, obesity, or the presence of implants or devices in the body can affect the clarity of the images.

A CT Angiogram of the Thoracic Aorta is an important diagnostic tool that can provide valuable information about the health of the aorta, and help guide treatment plans for aortic disease. It is important to discuss with your doctor the benefits and risks of this test to make an informed decision about your healthcare.
