Abstract
A rare paediatric case of vertebrovertebral arteriovenous fistula presented with a subarachnoid haemorrhage.
A 12 year-old boy, who fell on his back at school, presented with a one week history of headache, vomiting, and double vision. Computed tomography (CT) scan revealed subarachnoid haemorrhage.
Magnetic resonance imaging (MRI) demonstrated a tortuous vessel on the anterior surface of the spinal cord. Selective angiography showed an arteriovenous fistula of the left vertebral artery at the level of C1.
The venous drainage of the fistula refluxed into the medullary vein at the level of C6-7, and drained upwards into the posterior fossa veins. An endovascular detachable balloon technique was employed and complete occlusion of the fistula was achieved.
