[Doppler ultrasound diagnosis of increased intracranial pressure by comparison of 2 blood flow velocities in the extra- and intracranial segment of the internal carotid artery. 2: Findings in children with increased intracranial pressure].

We investigated the correlation between intracranial pressure and flow parameters by simultaneous Doppler sonographic flow measurements in the internal carotid arteries and estimation of the intracranial pressure over the anterior fontanelle. ⋯ Flow measurements in extra- and intracranial sections of the internal carotid arteries are an accurate method for semiquantitative estimation of increased intracranial pressure. This method is superior to the measurement of the RI. Slightly increased intracranial pressures below 20 cm H2O cause an increase of the I/E-ratio above 1, whereas the RI does not change. Moderately increase of the intracranial pressure above 20 cm H2O lowers the I/E-ratio significantly below normal values of 0.8, whereas the RI increases.
