Percutaneous transvenous embolization is one of the most effective treatments of intracranial dural arteriovenous fistulas (AVFs) involving the dural sinuses. We present a unique case of surgical transvenous embolization in a 48-year-old man with a dural AVF of the cavernous sinus who presented with intracerebral hematoma. The dural AVF drained only into the vein of the sylvian fissure on angio...

Dural arteriovenous fistulas (dAVFs) may present in a variety of ways, including as carotid-cavernous sinus fistulas. The ophthalmologic sequelae of carotid-cavernous sinus fistulas are known and recognizable, but less commonly seen is the rare clival fistula. Clival dAVFs may have a variety of potential anatomical configurations but are defined by the involvement of the venous plexus just over...

BACKGROUND Tinnitus, occurring at least once in a lifetime in about 10-20% of the population, is an important clinical problem with complex etiology. Rare causes of tinnitus include cranial dural arteriovenous fistulas (DAVFs), which are usually small lesions consisting of abnormal connections between branches of dural arteries and venous sinuses or veins. CASE REPORT Authors present a case o...

Objective: Selective transvenous embolization (sTVE) is an effective technique for treating dural arteriovenous fistulas (DAVFs); however, selective catheterization into the shunted pouch often difficult due to acute angle of access route between target and sinus. We present our initial experience using a steerable microcatheter (SM) manually control tip sTVE DAVFs.

Objective: Intracranial dural arteriovenous fistulas (AVFs) account for 10%-15% of all intracranial arteriovenous lesions. Some dural AVFs produce ocular symptoms include proptosis, diplopia, episcleral venous engorgement, periorbital swelling, extraocular muscle limitation, visual field defect, and papillaedema. Materials and Methods: We reviewed four patients who had dural AVFs with ophthalmi...

BACKGROUND AND PURPOSE The cause of spinal dural arteriovenous fistulas (SDAVF) is unknown. In intracranial dural arteriovenous fistulas, an association with factor V Leiden mutation has been found. Therefore, we studied the association between prothrombotic factors and SDAVF. METHODS Factor V Leiden mutation, factor II mutation, protein S, protein C, factor VIII, von Willebrand factor, antit...

SUMMARY Three cases of spontaneously closing dural arteriovenous fistulas (AVFs) are presented, and 11 previously published cases are reviewed. On the basis of clinical and angiographic data, two types of spontaneously regressing dural AVFs are distinguished: posttraumatic and spontaneous. In all cases, the explanation for spontaneous closure is unknown. Some authors have hypothesized that the ...

BACKGROUND AND PURPOSE The purpose of this study is to compare the angiographic and clinical characteristics of spinal epidural arteriovenous fistulas (SEAVFs) and spinal dural arteriovenous fistulas (SDAVFs) of the thoracolumbar spine. METHODS A total of 168 cases diagnosed as spinal dural or extradural arteriovenous fistulas of the thoracolumbar spine were collected from 31 centers. Angiogr...
