hiperperfusion
Hyperperfusion is the state of increased blood flow to a tissue that exceeds its metabolic needs or normal baseline. It can be physiological, such as during neural activity or after a meal, or pathological, arising when perfusion becomes excessive relative to tissue demand or when regulation of blood flow is disrupted.
Physiology and mechanisms: In healthy tissue, cerebral and systemic blood flow is largely regulated by autoregulation
Clinical contexts: Cerebral hyperperfusion syndrome (CHS) is a recognized complication after carotid revascularization procedures such as
Diagnosis: Imaging modalities that quantify regional blood flow, such as perfusion MRI, CT perfusion, or PET/SPECT,
Treatment and prognosis: Therapy targets the underlying cause and aims to prevent secondary injury. In CHS,
