Abstract
A treatment method for dural arterio-venous malformation of the posterior fossa was reported. The reported case was a 53 year-old male. The drainage veins were transverse and sigmoid venous sinuses. Under local anesthesia, 5 ml of aron alpha was injected through the occipital artery which was one of the main feeding arteries. Postoperative angiography revealed no opacification of the nidus even from the untreated tentorial artery. From this result it was considered that AVM was embolized almost completely. No side effects or complications of any nature occurred and the patients was discharged in ambulatory state. CT and cerebral angiography were performed six months after the operation with no evidence suggestive of recurrences. At present, one and half years after the operation, he lives well with no symptoms of recurrence.
