Stent-Assisted Coiling Techniques

  1. ‘jailing’ of microcatheter
    • stent deployed after the aneurysm is catheterized but before coil deployment
    • microcatheter pinned between intima and stent, coils are kept within the aneurysm and outside of vessel lumen

  2. ‘coil through’
    • stent fully deployed across aneurysm neck
    • aneurysm catheterized through the tines of the stent
    • b
  3. ‘coil stent’
    • unassisted coil embolization to completion followed by stent deployment
    • capitalizes on biologic benefit of vascular remodeling or to constrain a prolapsed coil loop

  4. ‘balloon stent’
    • stent placement after completion of balloon assisted embolization

  5. other techniques
    • coiling with ‘Y stent’ configuration for basilar tip aneurysms
    • depositing single or multiple stents for flow diversion for blister dorsal carotid wall aneurysms
