Patients with brain arteriovenous malformations (AVMs) had better short- and intermediate-term outcomes with conservative treatment (headache and seizure treatment combined with observation) than with surgical or endovascular treatment in randomized trials such as ARUBA. Whether surgical treatment provides greater benefit over a longer follow-up period is unclear. To examine longer-term outcomes, researchers analyzed data from a multicenter registry of almost 1800 patients (median age, 26 years; 60% men) with AVMs who received either conservative treatment or surgical, endovascular, or radiosurgical treatment within 6 months of diagnosis. The primary outcome was hemorrhage-free survival at 5 years; 10-year outcomes were secondary.
