“…It is widely hypothesized that some trigger factors, such as venous thrombosis, intracranial surgery, tumor, puerperium, trauma, hypercoagulable state and congenital causes, are associated with the occurrence of DAVFs [ 57 ]. Such stressors can weaken the structures of the dura mater, resulting in ‘recanalization’ of the vessels [ 55 , 57 ]. Houser et al suggested that the pathogenesis of DAVFs is related to angiogenic factors from thrombi, which may induce the proliferation of small DAVFs [ 30 ].…”

Intracranial dural arteriovenous fistulas (DAVF) are abnormal connections between intracranial arterial and venous systems within the dural layers. Intracranial DAVFs are rare but can occur wherever dural components exist. The pathogenesis of DAVFs is controversial. Venous hypertension is considered as a main cause of clinical symptoms which are subclassified into asymptomatic, benign and aggressive manifestations. To date, several classification schemes have been proposed to stratify the natural course and risks of DAVFs. Currently, endovascular therapy is the main treatment modality. Moreover, the use of radiosurgery and radiotherapy has been limited. Open surgery is also selectively performed as a main treatment modality for specific types of DAVFs and an adjunctive modality for the endovascular approach. Herein, we present a review of the general perspectives of intracranial DAVFs with an emphasis on the role of surgery.

“…Dural arteriovenous fistulas (DAVF) are rare acquired lesions defined as an abnormal shunt between the intracranial dural arteries and the venous system, accounting for 10% to 15% of all intracranial arteriovenous malformations (AVMs). 8)10) [15][16][17] The etiology of DAVFs is controversial, as venous thrombosis, intracranial surgery, tumor, puerperium, trauma, hypercoagulable state, and congenital causes have been found to be associated to these lesions. 16) These lesions are thought to arise from structural weaknesses of the dura coinciding with a trigger factor, such as venous thrombosis or injury due to mass effect from a tumor or local infection causing inflammation, fibrosis, and angiogenesis with the body compensating for this by attempts at recanalization.…”

Superior sagittal sinus dural arteriovenous fistula caused by treatment of meningioma masquerades as sinus thrombosis

Dural arteriovenous fistulas (DAVF) are rare acquired lesions resulting from abnormal shunting between intracranial dural arteries and venous system. Typically arising from structural weakness of the dura and a coinciding trigger factor, DAVFs can present with similar clinical and imaging characteristics to sinus thrombosis. A 61-year-old male with a history of meningioma previously managed with subtotal resection and stereotactic radiosurgery presented with progressive right-sided vision loss and bilateral papilledema. Initial imaging suggested possible sinus occlusion. Catheter angiogram revealed a Borden-Shucart grade III DAVF of the superior sagittal sinus and elevated venous pressures and the patient subsequently underwent endovascular transarterial intervention twice. We report on the first case of a superior sagittal sinus DAVF occurring after surgical resection of a parasagittal meningioma.

“…[1][2][3] The clinical course of DAVFs varies greatly, ranging from spontaneous regression to pulsatile tinnitus and severely debilitating ischemic events to even lifethreatening intracranial hemorrhage. 4,5 Because catheterized embolization therapy can eliminate DAVFs, 6 early diagnosis and management of DAVFs may prevent the occurrence of stroke. Cerebral conventional angiography is a standard diagnostic tool for DAVFs, and head CT and MR imaging have a diagnostic sensitivity of Ͼ80%.…”
