The preliminary result of endovascular treatment in spinal vascular malformation
Main Article Content
Abstract
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.
