Functional Magnetic Resonance-Based Observations of Brain Networks in Moyamoya Disease Patients Under Anesthesia
Sponsor: Beijing Tiantan Hospital
Summary
Moyamoya disease is characterized by progressive stenosis of the genesis of the distal internal carotid arteries bilaterally and progressive generation of compensatory pathological vascular networks at the basis cranii, and these pathological vasculature has poor vascular reactivity. Perioperative circulatory management of patients with smoky vessels to ensure perfusion of brain tissue and integrity of brain network during surgery to minimize postoperative impairment of neurological functions, including motor, sensory, emotional and cognitive functions, is the key point of perioperative circulatory management of moyamoya disease. Functional Magnetic Resonance Imaging (fMRI) has been routinely used in various cerebrovascular diseases to further evaluate cerebrovascular reserve and cerebral network connectivity. The purpose of this study is to observe the changes in cerebral blood flow, cerebral oxygen metabolism, cerebral oxygen metabolism rate, and cerebral network connectivity in adult patients with moyamoya disease in cerebral ischemia-sensitive areas under anesthesia to provide a basis for exploring anesthesia management to improve cognitive function and cerebral network connectivity in these patients.
