Clinical and Angiographic Characteristics of Multiple Dural Arteriovenous Shunts

Abstract

BACKGROUND AND PURPOSE:The pathogenesis and characteristics of multiple DAVSs are not wellknown. The purpose of this study was to evaluate the angiographic and clinical characteristics of patients with multiple DAVSs with an emphasis on the pathomechanism.

Progressive versus Nonprogressive Intracranial Dural Arteriovenous Fistulas: Characteristics and Outcomes

“…Only a few cases have been published in the past 15 years; therefore, the pathogenesis, presentation, clinical course, and treatment remain unclear. 4,[8][9][10][11][12] The purpose of this single-institution retrospective cohort study was to compare the clinical characteristics, angioarchitecture, and treatment outcomes of patients with progressive (enlarging fistulas or developing de novo fistulas) versus nonprogressive (recurrent original fistula or the presence of multiple unchanging fistulas) intracranial DAVFs.…”

“…Finally, one should be aware of the potential for both synchronous and metachronous separate dAVFs which, although rare, are more commonly seen in association with an aggressive presentation and may need to be addressed at another time as in our case [7].…”

A Case of De Novo Anterior Condylar Dural Arteriovenous Fistula Long after Curative Transvenous Embolization of Contralateral Anterior Condylar Arteriovenous Fistula

“…In some cases, multiple lesions are simultaneously found at the time of diagnosis and this is generally called multiple DAVFs. Recent studies revealed that these synchronous multiple lesions are found in 7~8% of intracranial DAVFs [3, 18]. On the other hand, second DAVF development in another sinus after resolution of the first lesion is rare.…”
