What procedure uses an angiographic approach to create an embolus in a vessel?

• A. Stenting
• B. Bypass surgery
• C. Embolization
• D. Ablation therapy

Answer: (C)

Embolization is a procedure that directly involves creating an embolus in a vessel using an angiographic approach. During this procedure, materials such as coils, particles, or liquid agents are introduced into the bloodstream to obstruct blood flow, effectively sealing off a blood vessel. This is particularly useful in treating conditions like tumors, arteriovenous malformations, or hemorrhages, where targeting specific blood vessels is essential for patient care.

The angiographic approach allows for real-time imaging that guides the interventional radiologist in targeting the correct vessel and optimizing the delivery of embolic agents. This precision is crucial for achieving therapeutic effects while minimizing impact on surrounding healthy tissues.

In contrast, stenting involves the placement of a mesh-like device to keep vessels open, bypass surgery reroutes blood flow around blocked vessels, and ablation therapy typically destroys tissue using heat or cold but does not involve creating an embolus in the same manner as embolization.
