Analysis of the best therapeutic alternative for intracranial dural arteriovenous malformations.
The material for this research consisted of 93 patients with dural arteriovenous malformations (DAVMs) who were studied retrospectively with regards to therapeutic success and failure, who had undergone either neurosurgery, or embolization or a combination of both methods and whose disease was located in the cavernous sinus, the superior sagittal sinus, the transverse-sigmoid sinus of the anterior fossa and the tentorium. Thus, it was possible to arrive at the following conclusions: treatment of the DAVMs must be indicated, jointly, by an interventionist neuroradiologist and a neurosurgeon; DAVMs of the transverse-sigmoid sinus were better treated when a combination of both methods was used; DAVMs of the tentorium were also better treated with a combined method; the endovascular method ensured only a 50% chance of therapeutic success for DAVMs of the superior sagittal sinus; DAVMs of the cavernous sinus are better treated when the endovascular method was used with a transvenous approach, relative to the transarterial approach.
