Malformations of the fetal dural sinuses.

Dural arteriovenous malformation of the major venous sinuses: an acquired lesion.

Arteriovenous malformations of the dura are thought to be congenital. However, arteriographic investigations of four patients who, after a head injury, developed dural arteriovenous fistulae with features of congenital malformations suggest that these abnormal communications may also be acquired. Thrombosis or thrombophlebitis in the dural sinus or vein may be the primary event in their formati...

Intracranial dural arteriovenous fistulas: classification, imaging findings, and treatment.

Intracranial DAVFs are pathologic dural-based shunts and account for 10%-15% of all intracranial arteriovenous malformations. These malformations derive their arterial supply primarily from meningeal vessels, and the venous drainage is either via dural venous sinuses or through the cortical veins. DAVFs have a reported association with dural sinus thrombosis, venous hypertension, previous crani...

Spontaneous Resolution of a Fetal Dural Sinus Thrombosis: One Case Report and Review of the Literatures

Bilateral Mirror Image Dural Arteriovenous Malformations Presenting with Aggressive Neurological Deterioration

Background: Multiple dural arteriovenous malformations occur rarely in the same individual. We describe a patient with bilateral, mirror image, dural arteriovenous malformations (DAVMs). This unusual case raises interesting questions regarding the origin of DAVMs. Case Description: We report the case of a 63-year-old hypertensive man who presented with the acute onset of confusion associated wi...

2D Thick-section MR digital subtraction angiography for the assessment of dural arteriovenous fistulas.

BACKGROUND AND PURPOSE Although dynamic contrast-enhanced MR angiography studies for arteriovenous malformations (AVFs) and brain tumors have shown promising results, no formal attempt has yet been made to similarly evaluate dural AVFs. To assess the practical applicability of 2D thick-section contrast enhanced MR digital subtraction angiography (MRDSA) for the diagnosis and management of dural...
