Intracerebral hemorrhage (ICH) is the deadliest, most disabling, and least treatable form of stroke. Approximately 40% of patients die within 1 month of ICH onset, and two-thirds of survivors never regain functional independence. Though guidelines for supportive care exist, there is currently no treatment that has been shown in a randomized-controlled trial to definitely improve outcome after ICH. Hematoma volume is a critical determinant of mortality and functional outcome after ICH, and early hematoma growth may be an important cause of early neurological deterioration.
