  5. aneurysmal rupture and any death within 1 year after embolization
  6. any stroke within 1 year after embolization
  7. any stroke, death hemorrhagic event, aneurysmal recanalization or retreatment within 1 year after embolization
  8. change in aneurysmal occlusion
  9. any comlicaion within 1 year after embolization
  10. %length of Hydrocoil, maximum diameter of aneurysm, volume embolization ratio.
