Combined neurosurgical and neuroradiological treatment of a complex superior sagittal sinus dural fistula: technical note.
OBJECTIVE
Dural arteriovenous fistulas of the superior sagittal sinus (SSS) account for 8% of intracranial dural fistulas. Their association with a thrombosis of the posterior part of the SSS is rare. In such cases, the usual neurosurgical and endovascular approaches cannot provide a good technical solution for treatment of the lesion, and a combined neurosurgical and neuroradiological approach is therefore needed.


METHODS
A 68-year-old man presented with rapidly evolving dementia. Cerebral angiography revealed a dural arteriovenous fistula of the SSS associated with thrombosis of the posterior part of the SSS. Various endovascular and neurosurgical approaches failed to cure the fistula.


METHODS
A burr hole was drilled in the frontal region, in the neurosurgical room. The patient was then transferred to the angiographic room, and the SSS was occluded using free spirals.


CONCLUSIONS
This procedure led to a complete anatomic cure of the fistula, and a slow clinical improvement was observed.
