Comparative Study
Reduced flow velocity in the internal carotid artery independently of cardiac hemodynamics in patients with cerebral ischemia.
To retrospectively investigate the relationships between carotid flow velocities, clinical features and cardiac hemodynamics to assess the meaning and significance of reduced carotid flow velocities in patients with cerebral ischemic symptoms. ⋯ Cardiac hemodynamics and carotid flow velocities are significantly related, only on the left side, probably due to larger hemodynamic stress. Increased intracerebral circulatory resistance is probably involved in the decrease in carotid flow velocity and increase in PI in patients with cerebral ischemic symptoms.
