“…In the sinus type of dAVF, the sinus may become occluded due to possible mechanisms including thrombogenesis associated with activated coagulopathy and hemodynamic hypertrophy of the sinus wall. 8,9,11 In our case with the nonsinus type, the occlusive change may occur through similar mechanisms.…”

The authors report an unusual case of a dural arteriovenous fistula (dAVF) draining only to the diploic vein and causing intracerebral hemorrhage. A 62-year-old woman presented with disturbance of consciousness and left hemiparesis. Brain CT scanning on admission showed a right frontal subcortical hemorrhage. Digital subtraction angiography revealed an arteriovenous shunt located in the region around the pterion, which connected the frontal branch of the right middle meningeal artery with the anterior temporal diploic vein and drained into cortical veins in a retrograde manner through the falcine vein. The dAVF was successfully obliterated by percutaneous transarterial embolization with N-butyl-2-cyanoacrylate. The mechanism of retrograde cortical venous reflux causing intracerebral hemorrhage is discussed.

“…1,2 Their pathogenesis has been explained variously, [2][3][4] and they are thought to be sequelae of venous thrombosis or occlusion that leads to venous hypertension. 3,4 Although DAVFs can arise anywhere within the dura mater, the most frequent sites are the transverse-sigmoid and cavernous sinuses. DAVFs with cortical venous drainage carry an increased annual mortality risk of 10.4%; the risk is increased 8.1% for intracranial hemorrhage and 6.9% for non-hemorrhagic neurologic deficits.…”

Purpose: We compared gross characterization of intracranial dural arteriovenous fistulas (DAVFs) between unenhanced 3-tesla 3-dimensional (3D) time-of-flight (TOF) magnetic resonance angiography (MRA) and digital subtraction angiography (DSA).Methods: We subjected 26 consecutive patients with intracranial DAVF to unenhanced 3T 3D TOF MRA and to DSA. Two independent sets of observers inspected the main arterial feeders, fistula site, and venous drainage pattern on MRA and DSA images. Interobserver and intermodality agreements were assessed by k statistics.Results: Interobserver agreement was excellent for fistula site (¬ = 0.919; 95% confidence interval [CI], 0.805 to 1.000), good for main arterial feeders (¬ = 0.711; 95% CI, 0.483 to 0.984), and very good for venous drainage (¬ = 0.900; 95% CI, 0.766 to 1.000). Intermodality agreement was excellent for fistula site (¬ = 0.968; 95% CI, 0.906 to 1.000) and good for main arterial feeder (¬ = 0.809; 95% CI, 0.598 to 1.000) and venous drainage (¬ = 0.837; 95% CI, 0.660 to 1.000).Conclusion: Gross characterization of intracranial DAVF was similar for both imaging modalities, but unenhanced 3T 3D TOF MRA cannot replace DSA.

“…Extracranial arteries on the skull or under the skull base are often mobilized through the bone. Such active recruitment of feeders is considered to be due to angiogenesis enhanced by the expression of vasculogenetic factors at the affected dura (including vascular endothelial growth factor (VEGF)) [11][12][13][14][15][16] . The next key process in maturation of the DAVF is the occlusive change of the draining system.…”

“…Next, the same process progresses in the upstream side because the remaining upstream drainage with more hemodynamic stress may yield the hypertrophic change of sinus wall 12,23 . As a result, the meeting point of the shunt flow will be isolated, and shunt flow without exit to the sinus may reflux into cortical veins (Fig.…”
