Intravertebral canals vascular malformations treated by superselective embolization / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To assess the feasibility superselective embolization using microcatheters in treatment of intravertebral canal vascular malformation.</p><p><b>METHODS</b>In 128 patients with intravertebral canals vascular malformation, their AVMS or fistulae were treated with silk thread, Ivalon microspheres or tungsten microcoils.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>Superselective embolization through microcatheter is effective in the treatment of intraspinal canal vascular malformations.</p>
