What am I looking at?
Visual recognition
Angiographic catheter with a curled pigtail distal tip and multiple side holes distributed near the loop, distinguishing it from end-hole selective catheters.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
High-flow flush catheter for aortography and venography, dispersing a large contrast bolus while limiting recoil and vessel injury. Typical procedural contexts include aortogram, pelvic angiogram, cavogram, and venogram.
What most clearly distinguishes it from similar devices?
Key distinctions
Unlike selective end-hole catheters, the pigtail configuration and multiple side holes disperse a high-flow contrast bolus broadly while reducing focal jetting and catheter recoil.
