A patient presenting with sudden onset of backache, paraparesis and urine retention was found to have low thoracic intramedullary lesion on MRI. A juvenile-type arteriovenous malformation was observed through a posterior approach, but feeding arteries could not be found in spite of lateral and also anterolateral exploration. Multiple feeders via anterior and posterolateral spinal arteries were observed on the first spinal selective angiogram. Emboiization could not be performed because of iatrogenic spinal subarachnoid haemorrhage. Embolization was achieved through a sulcal artery via anterior spinal axis during the second session. Patient's symptoms relieved progressively after the embolization. This result suggests that embolization is the preferred modality for treatment of the Juvenile-type spinal arteriovenous malformations (AVM's).
