Aims and objectives: Spinal vascular malformations (SAVMs) are rare diseases with a wide variety of neurologic presentations. They can be classified into three main groups (Rodesch et al, Neurosurgery 2010):   - Genetic hereditary lesions   - Genetic nonhereditary lesions   - Sporadic spinal art[...]

Methods and materials: We identified 6 patients treated for SC pial AVMs in national institute of neurology of Tunis between 2012 and 2016: 5 men and one woman Age ranged from 8 to 68 years 4 patients got MRI before angiogram

Results: Clinical presentation and symptoms were motor and or sensory deficit associated to bladder dysfunction in two cases. There were 4 pial arteriovenous fistula and 2 AVMs. Endovascular treatment was performed exclusively in all patients. Glue was injected in 4 patients and Onyx in 2 cases. Two patient[...]

Conclusion: Discussion: 1) Anatomy and epidemiology Spinal cord AVMs are fed by radicullomedullary and/or radiculopial, spinal cord feeding arteries, and drained by spinal cord veins. There is no gender difference and a predominance for presentation in the 2nd decade of life. Ectasia of the vein usually [...]
