Background: Dural arteriovenous fistulas (DAVF) are unusual intracranial vascular malformations consisting of anomalous connections between meningeal arteries and dural sinuses or the veins that pass through them. They have variable clinical presentation and prognosis, which depend on their location and venous hemodynamics. Treatment is based on the closure of the abnormal connections, which is usually conducted via arterial and/or transvenous endovascular techniques. Case Description: We present a male patient who complained of headaches and left-sided pulsatile tinnitus due to DAVF from the external carotid artery branches draining directly into the ipsilateral sigmoid sinus...

Traumatic pseudoaneurysms of middle meningeal artery (MMA) and medial sphenoid wing dural arteriovenous fistula (dAVF) are rare. These lesions usually result from traumatic brain injury, and associated with skull fracture. In this paper, the authors report a case of a patient with a ruptured traumatic pseudoaneurysm of MMA and medial sphenoid wing dAVF presented with an intracerebral hemorrhage in the left temporal region and subarachnoid hemorrhage. These lesions were completely obliterated by endovascular treatment, and the patient was recovered without any neurologic deficit...

Intracranial dural arteriovenous fistulas (DAVFs) are complex intracranial vascular malformations that may lead to hemorrhage. Although the precise mechanisms by which DAVFs occur remain unknown, dural angiogenesis may be a vital factor in its pathogenesis. Nuclear factor erythroid 2-related factor 2 (Nrf2) significantly influences angiogenesis; however, the association between DAVF and Nrf2 remains unclear. Therefore, the present study investigated whether DAVF alters the expression of Nrf2 in an experimental animal model of DAVF...

Posterior condylar canal dural arteriovenous fistula (PCC dAVF) is a rare entity with only three cases having been reported so far in the English literature. We describe the clinical presentation, imaging, and endovascular management of an elderly man with left PCC dAVF presenting with subarachnoid haemorrhage (SAH). Endovascular management of such cases requires thorough understanding of the vascular anatomy around the craniovertebral junction (CVJ) and variable bridging vein draining patterns. The fistula in our case was fed by the posterior meningeal branch of the left vertebral artery and was draining through a dilated and tortuous medullary bridging vein into the antero-lateral pontomedullary venous system...

PURPOSE: Computed tomography angiography (CTA) and magnetic resonance imaging/angiography (MRI/MRA) are used for the diagnosis of intracranial dural arteriovenous fistulas (DAVFs). The purpose of this study was to compare the diagnostic accuracy of CTA and magnetic resonance imaging/angiography (MRI/MRA) for detection of cortical venous reflux (CVR) in intracranial DAVFs. METHODS: The records of patients with angiography-confirmed intracranial DAVFs who also received CTA and MRI/MRA from January 2008 to July 2016 were reviewed...

BACKGROUND: Ethmoidal dural arterio-venous fistulas (DAVFs) are rare and aggressive lesions, usually treated by microsurgical disconnection of the fistula. Transarterial embolization is rarely performed because of the risk of retinal ischemia. Transvenous embolization has been reported as an alternative approach. We describe our experience in transvenous embolization of ethmoidal DAVFs and review the literature focusing on technical and safety aspects of the procedure. METHODS: We retrospectively identified 4 patients with ethmoidal DAVFs treated by transvenous embolization in a single centre...

Arterial aneurysms are uncommon among patients with dural arteriovenous fistulae (DAVFs), and there is limited information available to guide treatment decisions in such cases. We performed a systematic review of the literature, including a case of a DAVF associated with a flow-related intraorbital ophthalmic artery (OA) aneurysm that we have recently managed. The purpose of our study was to clarify epidemiology, natural history, and management of these lesions. A total of 43 published cases of DAVF associated aneurysms were found in 26 studies on the topic...

For dural arteriovenous fistula (DAVF), when the usual endovascular or neurosurgical approaches are difficult to treat, multi-modal treatment can be helpful. We present a case of a 71-year-old woman with DAVF, who presented with an intracerebral haemorrhage. Digital subtraction angiography revealed a DAVF of the transverse sinus, with cortical venous reflux. Transvenous and transarterial approaches for coil embolization failed. In the operating room, a small craniotomy was performed, and coil embolization was done under fluoroscopy...

Transvenous embolization is an effective method for treating dural arteriovenous fistulas (DAVFs) of the transverse-sigmoid sinus (TSS). However, in cases of complicated DAVFs, it is difficult to preserve the patency of the dural sinus. The authors describe the technical details of a new reconstructive technique using transvenous balloon-assisted Onyx embolization as another treatment option in a patient with an extensive and complex DAVF of the left TSS. A microcatheter and compliant balloon catheter were navigated into the left internal jugular vein and placed at the distal end of the DAVF in the transverse sinus...

OBJECTIVE Cranial dural arteriovenous fistulas (DAVFs) have been associated with dural sinus occlusion, and previous reports have suggested the association of hypercoagulability with some cases. But the prevalence of a hypercoagulable state has not been systematically analyzed in conjunction with laboratory markers and clinical manifestations, including history of thromboembolism or systemic malignancy. The authors hypothesize that laboratory or clinical evidence of a hypercoagulable state, including cancer, is commonly identifiable in consecutively identified patients with DAVFs, with implications for clinical management...

Intracranial dural arteriovenous fistulae (DAVF) are complex vascular malformations consisting of a pathological shunt located between meningeal arteries and drainage to dural venous sinuses and/or cerebral veins. We report an unusual anatomical variation, resulting in a DAVF forming between the superior sagittal sinus and an anomalous origin of the middle meningeal artery (MMA) arising from the left ophthalmic artery. We present an atypical case requiring mini-craniotomy for catheter access, as well as cannulation of extracranial arterial supply prior to embolization of a Cognard type IIa+b fistula...

BACKGROUND: Dural arteriovenous fistulas (DAVFs) are usually seen in relation to the venous sinuses, but in certain rare instances fistulas may not drain directly into the venous sinuses but rather drain into the cortical veins. This rare form of DAVF may present with either intracranial hemorrhage or myelopathy. The mode of clinical presentation is influenced by the venous outflow into either intracranial drainage or caudally intraspinal drainage. OBJECTIVE: To evaluate the clinical presentations, angioarchitectural characteristics, and treatment of 12 patients who presented with DAVF in the region of the foramen magnum...

The association of dural arteriovenous fistulas (DAVF) in children with Vein of Galen malformation (VGM) has recently been reported for the first time. In a larger series of cases treated with transarterial NBCA embolization, 30% had DAVF. We wanted to analyze the development of DAVF in our cohort of children with VGM and to evaluate whether their occurrence depends on different treatment timing and embolic materials. We analyzed 43 VGM cases treated with a combined transarterial and transvenous approach between 2003 and 2016...

A 56-year-old man experienced a sudden onset of left hemiparesis. The computed tomography(CT)scan revealed a lobar hemorrhage in the right fronto-parietal lobe. After his admission, deep vein thrombosis was detected in his left lower limb, and angiograms taken on the 36th day of hospitalization revealed cerebral venous sinus thrombosis. Anticoagulant treatment was induced. After 21 months, he experienced a sudden onset of left hemiparesis again. The CT scan revealed a new lobar hemorrhage in the right frontal lobe, and angiograms revealed that two dural arteriovenous fistulas(dAVF)developed in the superior sagittal sinus(SSS)and the left transverse-sigmoid sinus...

BACKGROUND: Administration of ε-aminocaproic acid (εACA), as adjuvant therapy following incompletely embolized cranial dural arteriovenous (dAVFs) and direct carotid artery to cavernous sinus fistulae (CCFs), is a strategy to promote post-procedural thrombosis. However, the efficacy of εACA to treat incompletely obliterated dAVFs and CCFs has not been published. The purpose of this study was to determine if administration of εACA following incomplete embolization of cranial dAVFs or CCFs was associated with an increased likelihood of cure on follow-up imaging compared with patients not given adjuvant εACA...

BACKGROUND: Treatment of thoracic spinal dural arteriovenous fistulas (DAVFs) by microsurgery has recently been approached using minimally invasive spine surgery (MISS). The advantages of such an approach are offset by difficult maneuverability within the tubular retractor and by the creation of "tunnel vision" with reduced luminosity to a remote surgical target. OBJECTIVE: To demonstrate how the pitfalls of MISS can be addressed by applying 3-D endoscopy to the minimally invasive approach of spinal DAVFs...
