Which type of catheter is typically used in angiography procedures?

• A. Balloon catheter
• B. Pigtail catheter
• C. Intravenous catheter
• D. Guide catheter

Answer: (B)

In angiography procedures, the pigtail catheter is typically used because of its unique design and function, which make it highly effective for visualizing and accessing vascular structures. The pigtail shape allows for easier navigation through the blood vessels while minimizing the risk of vascular trauma. It is specifically designed with multiple side holes, which facilitate contrast injection and provide better flushing capabilities during imaging, ensuring clear visualization of blood flow and vessel anatomy.

While other types of catheters serve important roles in different medical contexts, they do not offer the same specific advantages for angiography. For instance, a balloon catheter is primarily used for occlusion or dilation of blood vessels, and an intravenous catheter is typically used for fluid administration rather than imaging. A guide catheter assists in directing other catheters but is not primarily used for direct imaging purposes like the pigtail catheter. Therefore, the pigtail catheter stands out as the best choice for angiographic procedures due to its specialized design tailored for vascular imaging.
