Dural Arteriovenous Fistula of the Transverse-sigmoid Sinus with Pure Leptomeningeal Drainage : A Case Report

Abstract

We reported a case of dural arteriovenous fi ミ itula of

A rare case of dural arteriovenous fistula presenting as primary intraventricular hemorrhage

“…Thrombotic occlusion with subsequent recanalization of the dural sinuses is considered as the most common cause of a dural fistula. [ 7 8 9 10 ] dAVF accounts for 10-15% of all intracranial vascular malformations and most commonly occurs along the transverse and sigmoid sinuses. [ 7 13 ] dAVF can present with a wide range of clinical manifestations like stroke due to ICH, TIAs, seizures, and cranial nerve palsies.…”

“…[ 7 13 ] dAVF can present with a wide range of clinical manifestations like stroke due to ICH, TIAs, seizures, and cranial nerve palsies. [ 7 8 9 10 ] ICH has been reported in up to 35-42% of dAVF and may be in the form of intraparenchymal, subarachnoid, subdural and intraventricular hemorrhage with various combinations. [ 13 ] However, dAVF presenting as PIVH is very rare and there are only few case reports.…”

“…[ 3 5 7 ] PIVH is a rare presentation of a dural arteriovenous fistula (dAVF). [ 7 8 9 10 ] dAVF is vascular malformations that consist of an AV shunt in the wall of a dural sinus without an intervening nidus. [ 7 11 12 ] Purpose of presenting this case is to emphasize that all patients with PIVH should undergo catheter angiography to find the etiology, and condition like dAVF though rare is potentially treatable.…”

Recurrence of the cavernous sinus dural arteriovenous fistula at adjacent sinuses following repeated transvenous embolizations: case report and literature review

“…[5][6][7][8][9][10]23 However, seven cases demonstrating a new DAVF following endovascular treatments have been reported (Table). 4,[11][12][13][14][15][16] In these DAVFs, new lesions occurred in either the ipsilateral TS-SS or the jugular vein. TVE was performed in four cases, TVE with transarterial embolization (TAE) in two, and TAE in one, respectively.…”

“…[5][6][7][8][9][10] However, some reports have demonstrated an appearance of a new DAVF following endovascular treatment. 4,[11][12][13][14][15][16] We herein present a case of a cavernous sinus (CS) DAVF which recurred in the ipsilateral inferior petrosal sinus (IPS) and then in the sigmoid sinus (SS) in spite of repeated TVEs, and discuss the mechanism of a recurrence of the DAVF.…”
