  • Look Inside

Dural arteriovenous fistulae (DAVF's) in the anterior cranial fossa are uncommon. We encountered three patients with DAVF's in the anterior cranial fossa and reviewed the pertinent literature with regard to the etiology. All patients are middle-aged males. Two of three patients had massive intracranial hemor-rhage, subarachnoidal hemorrhage in one and subdural hemorrhage in the other. One patient had a rup-tured middle cerebral artery aneurysm and DAVF at the anterior cranial fossa was detected only inciden-tally. Angiographically, blood supplies were from the bilateral enlarged anterior ethmoidal arteries. These drained into the superior sagittal sinus via dilated frontal cortical veins. In all the patients, coagulation of the fistulous connections was carried out and the postoperative courses were uneventful. Angiographies re-vealed complete disappearance of the DAVF's.

In conclusion, compared to cases of DAVF's in the other locations, DAVF's of the anterior cranial fossa are more likely to be brought on by sudden massive intracranial hemorrhage, and should be treated, even if asymptomatic, at the time of diagnosis. Surgical obliteration of the fistulous connection is sufficient treat-ment for DAVF in the anterior cranial fossa. Literature review strongly suggests that DAVF's involving the anterior cranial fossa are acquired lesions.
