Hemorrhagic transformation is a common complication of acute ischemic stroke patients . BBB injury often occurs in the early stage of ischemic stroke, leading brain tissue edema or even hemorrhagic transformation with the development of ischemic injury. The biomarker of BBB damage, such as the level of serum occludin, can reflect the extent of BBB injury. So, the investigators hypothesis the level of BBB damage biomarker is predictor of intracranial hemorrhage following ischemic stroke.
Hemorrhagic transformation is a common complication of acute ischemic stroke patients . BBB damage is regarded as a major pathophysiological mechanism of hemorrhagic transformation. So, the investigators hypothesis the level of BBB damage biomarker is predictor of intracranial hemorrhage following ischemic stroke.
