Methods Twenty-one patients with cervical spinal cord vascular malformations who were admitted from January 1991 to June 2000 were enrolled in this study. Their clinical manifestations and angiographic features were analyzed. All patients underwent endovascular embolization. Results of which 3 cases in 6 months after surgery ~ 2 years, due to the huge lesions, the second line of treatment. Embolization material selected silk particles or line 10 cases, 3 cases of NBCA glue, line and NBCA glue combination of 8 cases. Among the patients with focal occlusion of more than 90%, 7 cases were occluded, 80% ~ 90% were occluded, 4 cases were 60% ~ 80%, 2 cases were less than 60%; 15 cases were improved in clinical symptoms, 5 cases were unchanged, 1 case was postoperatively 3 Month of death. Conclusion Endovascular embolization is an effective treatment for cervical spinal cord vascular malformations
