background traditional digital subtraction angiography (dsa) is currently the gold standard diagnostic method for the diagnosis and evaluation of cerebral arteriovenous malformation (avm) and dural arteriovenous fistulas (davf). objectives the aim of this study was to analyze different less invasive magnetic resonance angiography (mra) images, time-resolved mra (tr-mra) and three-dimensional ti...

Dural arteriovenous fistulas are contained within the dural leaflets, making them a unique shunt of central nervous system. Those without cortical venous drainage may be found incidentally or in workup pulsatile tinnitus ocular symptoms. These symptoms also occur setting drainage, but additionally, seizures, neurological deficits, even frank hemorrhage because disruption normal parenchymal outf...

Dural arteriovenous shunts and pial arteriovenous fistulas are uncommonly associated. Their etiology, pathogenesis, and natural history are still unclear and are likely different. We present three cases of high-flow dural arteriovenous shunts associated with pial arteriovenous fistulas and discuss their pathogenesis, anatomic association, and angioarchitecture. We propose that venous steal effe...

Objective: To report our experience with the endovascular management of cerebral arteriovenous malformations and dural arteriovenous fistulas. Methods: Fifty patients (66% males and 34% females) with cerebral arteriovenous malformations and dural arteriovenous fistulas were treated in our department between September 2007 and April of 2010 using endovascular therapy. A total of 84 endovascular ...

BACKGROUND We report a unique case of an acquired pial arteriovenous fistula occurring after an asymptomatic thrombosis of a superficial cerebral vein. CASE DESCRIPTION A cerebral angiogram performed in a 51-year-old man with subarachnoid hemorrhage revealed a 10-mm ruptured anterior communicating artery aneurysm and a thrombosed left superficial middle cerebral vein. Coil embolization of the...

PURPOSE Status epilepticus was rarely reported as the initial manifestation of intracranial dural arteriovenous fistulas. Successful treatment with endovascular intervention has not been reported in the literature. CASE REPORT We report three cases of dural arteriovenous fistulas initially presenting with various types of status epilepticus, including generalized tonic-clonic status epileptic...

Dural arteriovenous fistulas are acquired lesions that usually involve the dura around the cavernous sinus. The transverse, sigmoid, and superior sagittal sinuses may be affected occasionally. With the exception of bilateral cavernous sinus dural arteriovenous fistulas, the simultaneous occurrence of dural arteriovenous fistulas at two locations is rare. Among 105 patients evaluated for dural a...

BACKGROUND AND PURPOSE Spinal dural arteriovenous fistulas are commonly missed on imaging or misdiagnosed as inflammatory or neoplastic processes. We reviewed a consecutive series of spinal dural arteriovenous fistulas referred to our institution that were missed or misdiagnosed on initial imaging and studied the clinical consequences of missing or misdiagnosing the lesion. MATERIALS AND METH...

BACKGROUND AND PURPOSE A minority of intracranial dural arteriovenous fistulas progress with time. We sought to determine features that predict progression and define outcomes of patients with progressive dural arteriovenous fistulas. MATERIALS AND METHODS We performed a retrospective imaging and clinical record review of patients with intracranial dural arteriovenous fistula evaluated at our...
