The auditory Brainstem responses (ABR) recorded from 22 patients with cerebrovascular diseases were analyzed within 2 weeks after the onset. The patients were divided into the following three groups according to the site of damage: supratentorial lesion, infratentorial lesion, and aneurysm.
In those with supratentorial lesions, ABR were sensitive to supratentorial herniation and useful for predicting the prognosis. On the other hand, there was a poor correlation between the prognosis and ABR findings in patients with infratentorial lesions or aneurysms.
The condition of patients with aneurysm varied with vascular spasm and rerupture, and it was difficult to predict the outcome at an early stage. In patients in deep coma due to infratentorial lesions, no ABR were detected in the early stage, and later V waves were seen. These data suggest that the absence of all ABR waves does not always indicate brain death.
