Aortography is a medical imaging technique used to visualize the aorta, the largest artery in the human body. This procedure is a type of angiography, which involves the use of contrast media to enhance the visibility of blood vessels on X-ray images.

Procedure

Aortography is typically performed in a catheterization laboratory. The procedure begins with the insertion of a catheter into a large artery, usually the femoral artery in the groin. The catheter is then guided through the vascular system to the aorta. Once in place, a contrast agent is injected through the catheter, and X-ray images are taken to capture the flow of the contrast through the aorta.

Indications

Aortography is indicated for several conditions, including:

• Aortic aneurysm
• Aortic dissection
• Congenital heart defects
• Atherosclerosis

Risks and Complications

As with any invasive procedure, aortography carries certain risks. These may include:

• Allergic reaction to the contrast material
• Bleeding or hematoma at the catheter insertion site
• Infection
• Kidney damage due to contrast

Advances in Aortography

Recent advances in imaging technology have improved the safety and efficacy of aortography. Digital subtraction angiography (DSA) and computed tomography angiography (CTA) are modern techniques that provide clearer images with less contrast material.
