[Intravertebral canals vascular malformations treated by superselective embolization].
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. CONCLUSION: Superselective embolization through microcatheter is effective in the treatment of intraspinal canal vascular malformations.
