Encephaloduroarteriosynangiosis (EDAS) is widely used as an indirect technique for treatment of moyamoya disease. Nevertheless, this indirect surgery tends to establish insufficient collateral circulation in most adult MMD patients. Nowadays, there is a lack of adjuvant therapies for improving collateral circulation induced by indirect revascularization. Remote ischemic conditioning (RIC) is a noninvasive approach protecting the brain by inflating and deflating blood-pressure cuff placed on the upper limbs. It has been confirmed to improve cerebral perfusion by promoting angiogenesis and arteriogenesis in ischemic animal brain. In addition, daily remote ischemic conditioning is a promising technique to ameliorate chronic cerebrovascular disease like intracranial atherosclerotic stenosis, small-vessel disease.~Thus, this study aims to explore whether remote ischemic conditioning can improve the collateral circulation after indirect revascularization.
