The role of the disturbance of cerebral microcirculation in ischendc brain injury after subarachnoid hemorrhage

Abstract

Although the treatment of aneurysrnal subarachnoid herrorrhage （SAH） has made cortsiderable progress in recent years, its mortality and disability have not been effectively controlled. Ischemic brain injury after SAH is considered to be an important reason for the poor prognosis of patients; however, its mechanism is still not fully understood. Studies have shown that the cerebral microcirculation disturbance after SAH is closely associated with iSchemic brain injury. This article reviews the advances in research on cerebral rnicrociroalation disturbance and ischemic brain injury after SAH. Key words: Subarachnoid Hemorrhage; Vasospasm, Intracranial; Brain Ischemia; Cerebrovascular Circulation; Blood-Brain Barrier; Vasoconstriction
