Association between draining vein diameters and intracranial arteriovenous malformation hemorrhage: a multicentric retrospective study

ConclusionIn this study, after adjusted analysis, the variables associated with intracranial AVM hemorrhagic presentation were a young age, a small nidus diameter, a deeply located nidus, a single draining vein, and large draining vein diameters. A draining vein diameter cutoff ≥ 5 mm was positively associated with the risk of AVM rupture. A large and prospective study is now necessary to confirm if draining vein diameter is a risk factor for AVM hemorrhage.
