In China, primary intracerebral hemorrhage accounts for 80-85% of all types of intracerebral hemorrhage, while cerebral amyloid angiopathy-related intracerebral hemorrhage is the second factor, accounting for approximately 20-30%. It is often characterized by repeated and multifocal lobar hemorrhage, which will not only cause neurological deficit on the limbs, but also influence the cognitive level of patients and may even be life-threatening. At present, the role of surgery in CAA-related ICH is controversial, and there is no effective prevention and treatment strategies have been established. Additionally, it is always associated with a low rate of good prognosis(11%-60%) and a high risk of recurrent ICH (10%-60%). Thus, a novel approach which can improve the clinical outcome and reduce the risk of recurrent intracerebral hemorrhage is urgently needed.~Remote ischemic conditioning (RIC) has been developed as a neuroprotective strategy to prevent and treat acute ischemic stroke and small cerebrovascular disease. Additionally, clinical research testified that RIC is safe and feasible for patients with subarachnoid hemorrhage. In animal studies, RIC is efficiency in accelerating the absorption of hematoma. Therefore, the investigators plan to carry out this research to evaluate the safety and efficacy of RIC in patients with CAA related ICH.
