Cerebrovascular reserve capacity (CVR) measures how much cerebral blood flow can increase. Reduced CVR may indicate higher stroke risk, especially in asymptomatic carotid stenosis, suggesting its potential as a diagnostic tool.

Area of Science:

  • Neurology
  • Vascular Medicine
  • Medical Imaging

Context:

  • Cerebrovascular reserve capacity (CVR) quantifies the brain's ability to increase cerebral blood flow (CBF) under stimulation.
  • CBF can be measured noninvasively using transcranial Doppler sonography (TCD), PET, or SPECT.
  • Stimulation methods include CO2 inhalation, acetazolamide injection, breath holding, or hand-gripping.

Purpose:

  • To evaluate the role of CVR in assessing cerebrovascular disease and guiding clinical decisions.
  • To discuss the controversial relevance of CVR in the context of carotid artery stenosis and stroke etiology.
  • To explore CVR's potential as an additional diagnostic parameter for surgical indications and risk stratification.

Summary:

  • CVR measurement provides insights into hemodynamic compromise, particularly in internal carotid artery (ICA) stenosis.

  • While stroke in ICA stenosis is often embolic, reduced CVR is linked to increased infarction risk, especially in asymptomatic cases.
  • CVR may help identify patients benefiting from bypass surgery or those at high risk for cerebral ischemia.

    • Impact:

    • CVR could refine surgical indications for carotid stenosis, particularly when the degree of stenosis is borderline.
    • It may aid in identifying high-risk patients for cerebral ischemia, including those with cerebral microangiopathy.
    • Further research is needed to validate CVR's predictive value for routine neurovascular diagnostics and surgical risk assessment.
