Impaired compliance of the intracranial vessels in complicated childhood migraine. Demonstration by transcranial Doppler-sonography--a vascular model approach.


AIM To increase the diagnostic value of Doppler sonography a uniform lumped parameter model of pulsatile blood flow in human arteries was derived from the serial and/or parallel connection of parallel oscillatory circuits. METHODS AND PATIENTS In this setting the current (I) in the ohmic resistor (R) represents the volume flow in the vessel, the voltage… (More)
