title: [Intravertebral canals vascular malformations treated by superselective embolization].
abstract: OBJECTIVE
  To assess the feasibility superselective embolization using microcatheters in treatment of intravertebral canal vascular malformation.
  
  
  METHODS
  In 128 patients with intravertebral canals vascular malformation, their AVMS or fistulae were treated with silk thread, Ivalon microspheres or tungsten microcoils.
  
  
  RESULTS
  In the 128 patients, 120 fistulae disappeared completely, but 8 were embolized 60% - 80%. Symptoms were improved in 113 patients. Improved muscular strength from grade I to IV was obtained in 8 patients, from grade II to III in 32, from grade III to IV in 32, and from grade IV to V in 41. The symptoms did not change in 15 patients.
  
  
  CONCLUSIONS
  Superselective embolization through microcatheter is effective in the treatment of intraspinal canal vascular malformations.
