经颅多普勒卧立位试验在脑血管病中的应用进展OA北大核心CSTPCD

Cerebral autoregulation(CA)is essential for maintaining normal cerebral blood perfusion,which is crucial for ensuring people's normal daily life and work.CA disorders can occur at any age but are particularly common in patients with cerebrovascular diseases or neurodegenerative diseases.The recumbent-upright test using TCD is a non-invasive and convenient method to assess CA.The key is to monitor the changes in cerebral blood flow velocity and vascular resistance during the transition from supine to upright position.The recumbent-upright test using TCD has significant clinical value in the diagnosis,treatment,and prognostic assessment of cerebrovascular diseases and autonomic dysfunction.However,challenges such as standardized operation,result interpretation,and individual variability hinder its clinical application.In the future,with the advancement of technology and in-depth research,the recumbent-upright test using TCD is expected to play a greater role in individualized treatment and early diagnosis.This paper aims to provide a reference for maximizing its clinical utility.
