  • Abstract
  • Look Inside

 Intracranial pressure (ICP) and Cerebral blood flow of fifty-five patients meeting with the criteria of brain death were measured. The ICP was measured by the subarachnoid catheter method. Cerebral blood flows were detected by the techniques of conventional cerebral angiography, transcranial doppler (TCD) and endocrinological procedure.

 The ICP was increasing to the level of mean arterial pressure in all of the cases which were monitoring the ICP. In 13 cases carried out the cerebral angiography, all of the cases showing the non-filling phenomenon. However, cerebral blood flows of middle cerebral artery or ophthalmic artery were detected by TCD in 3 cases who were demonstrated non-filling on conventional angiography. Serum hypothalamic and pituitary hormones were inconsistently high based on half life time for presumed absence of cerebral blood flow on angiography. The responses to their releasing hormones were normal in sixteen patients. In the microscopic appearance of hypothalamus and anterior pituitary lobe by the post mortum examination, normal structure and cells were intermingled with lytic changes and necrosis.
