Observing brain networks in moyamoya disease patients under anesthesia

Functional Magnetic Resonance-Based Observations of Brain Networks and Cerebrovascular Reactivity in Patients With Moyamoya Disease Under Anesthetic Sedation, A Prospective Observational Cohort Study

Observational Beijing Tiantan Hospital · NCT06041659

This study looks at how brain blood flow and activity change in patients with moyamoya disease while they are under anesthesia to help improve their care during surgery.

What this trial studies

This observational study focuses on patients with moyamoya disease who are scheduled for revascularization surgery. It utilizes functional Magnetic Resonance Imaging (fMRI) to assess changes in cerebral blood flow, oxygen metabolism, and network connectivity during anesthesia. The aim is to understand how these factors influence neurological functions post-surgery, which is crucial for effective perioperative management. By monitoring these parameters, the study seeks to enhance the understanding of cerebral dynamics in patients with compromised vascular networks.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 with moyamoya disease scheduled for revascularization surgery.

Not a fit: Patients with severe preoperative conditions, such as significant cerebral infarction or those unable to cooperate with the examination, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved perioperative management strategies that minimize neurological impairments in moyamoya disease patients.

How similar studies have performed: While fMRI has been used in various cerebrovascular diseases, this specific application in moyamoya disease under anesthesia is relatively novel.
