[Analysis of angiographical findings in patients with severe brain disorders progressing to brain death].
In the present study, the authors analysed the serial angiographical findings progressing to brain death and their relation to the intracranial pressure (ICP) and the cerebral perfusion pressure (CPP). Seventy two patients, from four to eighty four years old (fourty six males and twenty six females) admitted in the Department of Emergency Medicine, University of Tokyo Hospital during the period from January, 1981 to April, 1986, were studied. Their underlying diseases were supratentorial primary brain lesions except two cases with asphyxias which progressed to brain death. ⋯ On the other hand, minimal flow ("Siphon-filling", "Partial-filling", "Delayed-filling") were still demonstrated in six brain death cases while ICP was approaching its "peak" value. This study showed that clinical diagnosis of brain death preceded the Non-filling phenomenon, suggesting that, for the demonstration of the cerebral circulatory arrest, the angiograms should be performed after the clinical diagnosis of brain death was established and CPP became zero. The evaluation of the extremely slow and minimal filling is still a matter of discussion.(ABSTRACT TRUNCATED AT 250 WORDS)
