[Noninvasive screening of cerebral death by Doppler sonography (author's transl)]. 1979

H J Büdingen, and G M von Reutern

Directional Doppler sonography of the supratrochlear and extracranial cerebral arteries was performed on 16 patients without any cerebral flow, as confirmed angiographically. The findings were inconsistent for the supratrochlear artery, but the internal carotid and vertebral arteries had characteristic changes in the Doppler curve with clearly diminished systolic flow velocity and flow reversal during diastole. These results were never seen in arteriosclerotic occlusion, hypoxaemic or toxic cerebral oedema. Doppler sonography thus helps to formulate indications for early cerebral angiography.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D001926	Brain Death	A state of prolonged irreversible cessation of all brain activity, including lower brain stem function with the complete absence of voluntary movements, responses to stimuli, brain stem reflexes, and spontaneous respirations. Reversible conditions which mimic this clinical state (e.g., sedative overdose, hypothermia, etc.) are excluded prior to making the determination of brain death.
