Abstract

SUMMARY


Purpose: to describe the imaging characteristics and the results of spinal arteriovenous shunt treated by endovascular
intervention.
Material and Methods: Descriptive and intervention study, patients were diagnosed and treated by endovascular intervention
at the Bach Mai hospital from 2012 to 2016. Imaging features were evaluated on MRI and DSA, evaluated of effectiveness of treatment based on the comparison of clinical symtoms, MRI imaging before and after endovascular treatment.
Result: Diagnosis and endovascular intervention of 20 patients. On MRI, the sign of spinal cord edema and dilated venous drainage were spotted in almost patients. The rate of complete angiographic obliteration was 60% patients and partial in 45.5% patients. After follow up of 3-6 months, spinal cord
damage reduce accounted 88.23% and 11.77% patients remain unchanged, clinically significance improvement was achieved in
82.35% patients,17.65% patients do not improve (3 cases are continous following).
Conclusion: MRI plays an important role in the diagnosis and follow up patients with spinal arteriovenous shunt, DSA is the gold standard for diagnosis and to allow intervention treatment with high effective.
