PURPOSE To describe the clinical presentation, angioarchitecture, and risks and problems of therapy in patients with dural arteriovenous malformations of the posterior fossa draining into subarachnoid veins. PATIENTS AND METHODS Twelve patients with dural arteriovenous malformations of the posterior fossa draining into subarachnoid veins were studied. RESULTS These fistulas often presented ...

BACKGROUND Dural arteriovenous fistulas are vascular malformations with variable clinical symptoms that range in severity from completely asymptomatic to seizures, dementia, loss of vision and intracranial hemorrhage. Historically, surgical obliteration was the treatment of choice but, more recently, endovascular embolization has become the first-line treatment. The liquid embolic agent Onyx (e...

THE collateral circulation that develops invariably in the vicinity of a systemic arteriovenous fistula has impressed generations of surgeons who have treated these lesions. Investigators in various surgical modalities have sought to apply this principle to enhance the blood supply of specific regional tissue. The most successful application to date has been the creation of femoral arteriovenou...

Intracranial hemorrhage is common and is caused by diverse pathology, including trauma, hypertension, cerebral amyloid angiopathy, hemorrhagic conversion of ischemic infarction, cerebral aneurysms, cerebral arteriovenous malformations, dural arteriovenous fistula, vasculitis, and venous sinus thrombosis, among other causes. Neuroimaging is essential for the treating physician to identify the ca...

A patient with rapidly progressive cognitive decline over an approximately four month period was suspected to have sporadic Creutzfeldt-Jakob disease. Features thought to support this diagnosis included psychiatric symptoms (anxiety and depression), visual hallucinations and a visual field defect. However, the finding of papilloedema broadened the differential diagnosis. Although standard brain...

A dural arteriovenous fistula was discovered incidentally in a 58-year-old man with activated protein C resistance who underwent routine outpatient cerebral angiography for workup of multiple intracranial aneurysms.

We report the description of a cardiac mass occupying almost the entire right atrium in a young man who developed paroxysmal supraventricular tachycardia during endovascular treatment of intracranial arteriovenous fistulas. The mass was detected at echocardiographic examination, its tissue characteristics were defined with cardiac magnetic resonance and it was successfully surgically removed. T...
