The preliminary result of endovascular treatment in spinal vascular malformation

SUMMARY

Objective: To evaluate the preliminary result of endovascular treatment in spinal vascular malformation.

Material and method: We prospectively studied patients with spinal arteriovenous shunt who were diagnosed and endovascular treatement with spinal arteriovenous shunt at Bach Mai hospital from 2012 to 2013. Clinical features were analyzed before and after treatment by Aminoff-Logue disability scale. MR imaging characteristics were evaluated.

Result: 9 patients were treated by endovascular embolization, 44.4% were spinal arteriovenous malformation, 55.6% were spinal dural arteriovenous fistulae. MRI studies showed intramedullary increased T2 signal and dilated venous drainage in all patients. The rate of complete angiographic obliteration was 55.5% and nearly occluded in 45.5 . After follow up of 3 months, clinically significance improvement was achieved in 66.7%, partial recovery in 22.2%.

Conclusion: n-BCA glue embolization for spinal arteriovenous shunt should be considered the treatment of choice with satisfactory outcomes. Large studies with longer follow-up are required to determinate the safety and efficacy of endovascular treatment.
