damage and fistula formation are known to occur (13). Formation of spinal arteriovenous fistulas (AVF) also has been reported as a delayed complication developing after lumbar surgery (3). We experienced spinal dural/epidural AVFs that developed at the site of previous lumbar surgery and successfully treated it with n-butyl cyanoacrylate (Histoacryl, B.Braun, Melsungen, Germany). To our knowled...

BACKGROUND AND PURPOSE DAVFs (dural arteriovenous fistulas) represent one of the most dangerous types of intracranial AV shunts. Most of them are cured by arterial or venous embolization, but surgery/radiosurgery can be required in case of failure. Our goal was to reconsider the endovascular treatment strategy according to the new possibilities of arterial embolization using non polymerizing li...

We present two patients with spinal epidural arteriovenous fistulas involving the vertebral body recruiting dural and osseous branches as feeders. The fistulas, forming a round venous sac into which the multiple arterial feeders converge, were located near the round bony defect of the vertebral body, suggesting the osseous component of this vascular lesion. Transvenous coil embolization of the ...

A 62-year-old woman was evaluated for tinnitis and headache. Magnetic resonance imaging and angiography revealed the coexistence of a tentorial tumor encroaching the junction of the right transverse-sigmoid sinuses, and dural arteriovenous fistulous malformation (AVFM) of the right transverse sinus. AVFM was not manipulated at all during the surgery. The pathology was fibroblastic meningioma. P...

Apparent diffusion coefficient (ADC) values at magnetic resonance imaging (MRI) are useful to distinguish vasogenic and cytotoxic edema due to cerebovascular diseases. Dural arteriovenous fistulas (DAVFs) with retrograde leptomeningeal venous drainage may cause cerebral edema by venous congestion. We report herein the course of ADC values of cerebral edema before and after endovascular treatmen...

AIM Spinal cord arteriovenous fistulas are rare cause of progressive myelopathy. The predictive factors of their outcome after endovascular or surgical treatment are still controversial. MATERIAL AND METHODS Twenty patients were diagnosed with spinal arteriovenous fistulas; 13 of them had dural and 7 had perimedullary fistulas (1 Dorsal and 6 Ventral). Surgery, endovascular or both treatments...

Background: Although the inferior petrosal sinus (IPS) is most common approach route for transvenous embolization (TVE) of cavernous dural arteriovenous fistulas (CSDAVFs), other routes should be chosen in cases which IPS occluded. We report a case superior ophthalmic vein (SOV) through facial (FV) was first choice to achieve radical cure hemorrhage-onset CSDAVF. Case Description: An 81-year-ol...

Although dural arteriovenous fistulas (DAVFs) occur in any structure that is covered by the dura mater, DAVFs at the posterior condylar canal have not been reported. We present a DAVF that involves the posterior condylar canal and drains into the posterior condylar vein and the occipital sinus, which was treated by selective transvenous embolization. Knowledge of venous anatomy of the craniocer...

Cerebral venous sinus thrombosis is an uncommon but potentially lethal condition that can present with headache, focal deficits, seizures, altered mental status, and papilledema. Nontraumatic dural sinus thrombosis is associated with medical conditions such as oral contraceptive use, pregnancy, dehydration, coagulopathies, connective tissue disorders, and leukemia. Traumatic dural sinus thrombo...
