What is a therapeutic use of angiography beyond diagnosis?

• A. Assessment of blood flow
• B. Treatment of aneurysms through coiling
• C. Monitoring post-operative outcomes
• D. Visualization of cardiac structures

Answer: (B)

Therapeutic angiography serves multiple functions, and treating aneurysms through coiling is a prime example. In this procedure, a catheter is inserted into the blood vessel and carefully navigated to the site of the aneurysm. Once in position, small coils are deployed into the aneurysm sac. These coils induce thrombosis, meaning they promote the formation of a blood clot within the aneurysm, preventing blood from flowing into it and significantly reducing the risk of rupture. This is a minimally invasive option that can significantly improve patient outcomes by addressing a potentially life-threatening condition.

While other options like assessing blood flow, monitoring post-operative outcomes, and visualizing cardiac structures are important aspects of angiography, they are primarily diagnostic or evaluative in nature rather than therapeutic. The ability to intervene and treat conditions such as aneurysms represents a significant advancement in the use of angiography for patient care.
