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; multiple side holes disperse contrast and reduce focal jetting. Typical contexts include aortography, pelvic angiography, cavography, and venography.
What most clearly distinguishes it from similar devices?
Key distinctions
Unlike a selective end-hole catheter, the pigtail’s multiple side holes distribute contrast broadly rather than directing a single focal jet.
