Objective To evaluate the treatment of spinal cord vascular malformations by endo vascular therapy. Methods All 41 patients including 3 cases were embolized by 3 0 silk line segments, 14 cases by selective embolization of dry dura particles, 16 by PVA and 8 cases by NBCA. Results Lesions were completely embolized in 27 cases, and partialy embolized in 14 cases. Paralysis of limbs were significantly improved in 36 cases, the other 5 cases showed no improvement on account of previous resection of the lesions. During 32 months follow up period, 18 cases recovered completely but with recurrence in 5. Conclusion Endovascular therapy is effective for spinal cord vascular malformations.
