Cerebral Hemodynamics

  • R. Aaslid
  • K.-F. Lindegaard


The principles of hemodynamics are the basis for understanding transcranial Doppler findings. Cerebral hemodynamics is a complicated subject because many factors are interacting. For example, the blood flow in a specific brain region is influenced by: 1. arterial pressure, 2. intercranial pressure, 3. hematocrit (viscosity), 4. degree of eventual proximal stenosis, 5. calibers and extent of collateral channels and 6. action of the cerebral autoregulation. It is the purpose of this chapter to describe the relationships between these factors and to serve as an introduction to hemodynamic interpretation of transcranial Doppler recordings in normal physiology as well as in patients with various forms of cerebrovascular pathology.
