Neuropathology of brain death in the modern transplant era

Abstract

No distinctive neuropathologic features were apparent in our series of patients with brain death. Neuronal ischemic changes were frequently profound, but mild changes were present in a third of the examined hemispheres and in half of the brainstems. Respirator brain with extensive ischemic neuronal loss and tissue fragmentation was not observed. Neuropathologic examination is therefore not diagnostic of brain death.
