UNASSIGNED: OBJECT @entity2457 ( @entity2457 ) are complex lesions consisting of abnormal connections between meningeal arteries and dural venous sinuses and/or cerebral veins. The goal of treatment is surgical or endovascular occlusion of the @entity292 or fistulous nidus or at least the disconnection of the feeding vessels and the draining veins. Delayed angiographic data on previously embolized dural fistulas is lacking. The authors report their experience and the long-term angiographic results with @entity887 of intracranial DAVF using Onyx. METHODS All cases of DAVF treated primarily with Onyx at the authors' institution from 2006 to 2013 were retrospectively reviewed. @entity1 demographics, @entity292 characteristics, @entity887 , and angiographic follow-up were analyzed. RESULTS Fifty-eight @entity1 with @entity2457 were treated during the study period. Twenty-two @entity1 were treated with open surgery with or without prior @entity887 . Thirty-six @entity1 were treated with @entity887 alone, of whom 26 underwent an attempt at curative @entity887 and are the subject of this review. All but 2 of these @entity1 were treated in a single session. Angiographic "cure" was achieved in all cases following treatment. Follow-up angiography was performed in 21 @entity1 at a mean of 14 months after treatment (range 2-39 months). Asymptomatic angiographic recurrence of the @entity292 was evident in 3 of the 21 @entity1 (14.3%). On reviewing the procedural angiograms of the cases in which the @entity2457 recurred, it was observed that the Onyx cast did not reach the venous portion in 1 case, whereas it did reach the vein in the other 2 cases. CONCLUSIONS Recurrence following initial angiographic cure of DAVF is not uncommon. Incomplete penetration of the embolic material into the proximal portion of the venous outlet may lead to delayed recurrence. Long-term angiographic follow-up is highly recommended.
