Management, risk factors and outcome of cranial dural arteriovenous fistulae: a single-center experience

Abstract

In general, intracranial DAVFs can be successfully surgically managed by simple venous disconnection in many cases. However, half of the patients do not show complete remission of symptoms. Age and the occurrence of perioperative complication were the most important determinants of outcome.

Prognosis and Treatment of Intracranial Dural Arteriovenous Fistulae: A Systematic Review and Meta-Analysis

“…One cohort was separated into two separate publications with fewer than 50 patients each, but we included both publications in the light of the total sample size . This left 34 cohorts meeting our mandatory inclusion criteria (http://onlinelibrary.wiley.com/doi/10.1111/ijs.12337/suppinfo), though none met all of our predefined ideal study characteristics (http://onlinelibrary.wiley.com/doi/10.1111/ijs.12337/suppinfo) .…”

“…One cohort was separated into two separate publications with fewer than 50 patients each, but we included both publications in the light of the total sample size (14,20). This left 34 cohorts meeting our mandatory inclusion criteria (Supporting Information Appendix S2), though none met all of our predefined ideal study characteristics (Supporting Information Appendix S3) (1,14,19–22,24–51).…”

“…In 20 studies where patients' management was specified and quantified, 269 of the 2513 patients (11%) were treated conservatively (14,20,21,24,25,28,(30)(31)(32)(33)(34)(36)(37)(38)41,43,44,46,50,51): during follow-up periods ranging from one-month to 210 month, seven patients (2·6%) died and nine (3·3%) suffered an ICH. Of the five studies describing untreated clinical course (14,20,25,36,47), the risk of ICH in the future was associated with the presence of a venous varix in one study (25) and presentation with an ICH in another (47).…”

Frequency and characteristics associated with inherited thrombophilia in patients with intracranial dural arteriovenous fistula

“…22 While the disease course for some DAVFs may be benign or non-progressive, depending on patterns of venous drainage, location of the fistula, and amount of shunting, other DAVFs may become aggressive, resulting in morbidity or even mortality. 5,11,21,29…”

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.…”
