Does the size of intracranial aneurysms change with intracranial pressure? Observations based on color “power” transcranial Doppler ultrasound

Abstract

The change in aneurysm size visualized with the aid of color power TCD is likely to be real. Aneurysm dimensions vary with ICP levels; the lesions are larger and less pulsatile at low ICPs and smaller but more pulsatile at high ICPs.
