Which diagnostic procedure is most useful for surgical planning in AAA repair?

• A. Angiogram
• B. Aortogram
• C. CT scan
• D. Ultrasound

Answer: (B)

The aortogram is particularly valuable for surgical planning in abdominal aortic aneurysm (AAA) repair because it provides detailed images of the aorta and any associated aneurysms. This imaging technique specifically focuses on the blood vessels, and by injecting a contrast dye into the aorta, it allows the surgical team to visualize the size and shape of the aneurysm, as well as its relation to surrounding structures. This information is crucial for determining the best approach for repair, selecting appropriate grafts, and assessing anatomical variations that could influence the surgical strategy. While other imaging modalities, such as a CT scan, are also commonly used in evaluating AAA, the aortogram offers real-time visualization of vascular anatomy and can sometimes be performed in combination with therapeutic interventions, making it a direct and effective choice for surgical planning.
