whether embolization with microspheres for end-arteries using a micro-balloon catheter allows the microspheres to penetrate further into smaller branches compared with flow-directed embolization.
1.8 Fr (O.D.) micro-balloon catheter (Attendant delta, Terumo clinical supply, Gifu, Japan)
Micro-balloon inflated condition allowed deeper penetration of microspheres during embolization in swine renal arteries model.
