Hypertension, Age, and Location Predict Rupture of Small Intracranial Aneurysms

Abstract

Among patients with small aneurysms (< or = 7 mm), hypertension, relatively young age, and posterior circulation were significant risk factors for rupture. Given the minimal long-term morbidity and mortality of treatment of unruptured aneurysms in large, tertiary medical centers, management of unruptured aneurysms 7 mm or smaller should be governed by factors other than size, specifically age, history of hypertension, and location.
