High-risk dural arteriovenous fistulae of the transverse and sigmoid sinuses.
نویسندگان
چکیده
Dural arteriovenous fistulae of the transverse and sigmoid sinuses are highly variable in symptomatology and prognosis. However, we have identified a subgroup of patients who have a high risk of hemorrhage and dementia due to severe venous overload caused by high arterial flow into the fistulae and by occlusive changes of the transverse and sigmoid sinuses. Three representative cases selected from 31 patients with dural arteriovenous fistulae of the transverse and sigmoid sinuses are presented, and 45 reported similar cases are reviewed to discuss pathophysiology and problems encountered during treatment.

Endovascular Treatment of Dural Arteriovenous Fistulas of the Transverse and Sigmoid Sinuses Using Transarterial Balloon-Assisted Embolization Combined with Transvenous Balloon Protection of the Venous Sinus.
BACKGROUND AND PURPOSE Combined transarterial balloon-assisted endovascular embolization with double-lumen balloon microcatheters and concomitant transvenous balloon protection was described as a promising treatment technique for dural arteriovenous fistulae of the transverse and sigmoid sinus. The purpose of this study was to evaluate the technical efficacy and safety of this combined treatmen...
متن کاملTentorial meningioma encroaching the transverse sinuses and sigmoid sinus junction area associated with dural arteriovenous fistulous malformation: a case report.
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...
متن کاملA case of dural arteriovenous fistula with retrograde intracranial venous flow.
PRESENTATION Dural arteriovenous fistulae are relatively rare lesions which can present a variety of different symptoms ranging from tinnitus to devastating intracranial hemorrhage. For those fistulae that require treatment, therapy is available in a wide range of options. We describe the case of a 60-year old patient who presented with a right occipital lesion presumably secondary to a dural a...
متن کاملIntraluminal Magnetic Resonance (MR) Findings of Dural Sinuses: Evaluation in Patients having Dural Arteriovenous Fistulas with Sinus Occlusion for Implications of Transvenous Embolization
Purpose Transcatheter angiography is the gold standard for evaluating the condition and anatomy of the dural sinuses in patients with arteriovenous fistulas (AVFs); however, the patency and intraluminal condition of the dural sinuses can also be evaluated on magnetic resonance imaging (MRI). The purpose of this study was to evaluate the usefulness of MRI for the diagnosis of sinus occlusion. Ma...
متن کاملMultiple dural arteriovenous fistulas of the cranium and spine.
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...
