Intracerebral hemorrhage (ICH) is the most serious complication of oral anticoagulant therapy (OAT). The growing use of OAT has resulted in an increase of fatal ICH. The mortality rate is about 65%, and most of the surviving patients remain disabled. While improvements in the treatment of spontaneous ICH have recently been described, there are no internationally accepted guidelines for managing patients with OAT-ICH. Therefore, identifying effective treatments is essential for improving clinical outcome. This article reviews the epidemiology of OAT-ICH, its pathophysiology, and current treatment options and discusses open questions with particular respect to more recent pharmacological therapies.
