Background

Flow aneurysms associated with arteriovenous malformations may increase risk of hemorrhagic presentation and unfavorable outcome but their natural history and management, following treatment of the associated malformation remain uncertain.

Methods

A retrospective observational study was performed (2008-2017), including all patients with symptomatic arteriovenous malformation, at least one flow related, conservatively managed aneurysm and angiographically complete resection or obliteration of the malformation following treatment.

Results

stronger proximal artery remodeling tracked with greater aneurysm regression

Distal feeding artery

More results

Eight patients harboring eleven flow aneurysms underwent surgical resection, with the remaining three patients receiving radiosurgery.

Distal type IIb flow related aneurysms were more likely to regress.

Conclusion · 1 of 2

Changes in proximal feeding artery diameter may help predict fate of flow aneurysms. Our findings support incorporating proximal feeding artery remodeling into post-treatment radiological assessment.

Conclusion · 2 of 2

With further validation, it may represent a biomarker for treatment efficacy in patients with flow aneurysms, and help inform personalized treatment strategies.
