   The 2013 ARUBA trial concluded that medical management alone is superior to medical management with interventional therapy for patients with unruptured brain arteriovenous malformations. A study was conducted to analyze AVM treatment and epidemiologic response to the ARUBA trial. Following ARUBA, there has been a stark decrease in interventions for uAVMs. Nationwide rAVM discharge incidence is inversely correlated with uAVM intervention rate. Less uAVM interventions may lead to a substantial inc
