Tentorial dural arteriovenous fistulae: endovascular treatment with transvenous coil embolisation

Tentorial arteriovenous dural fistulae are uncommon. They are aggressive le sions: of all intracranial dural fistulae they are the most likely to prese nt with haemorrhage. Treatment options include surgical excision or interru ption of leptomeningeal draining veins and arterial embolisation in isolati on or in combination with surgery. There has been one case report of treatm ent by percutaneous transvenous coil embolisation. We describe successful t ransvenous coil embolisation of two tentorial dural fistulae presenting wit h subarachnoid haemorrhage.
