Detection of early circulatory and electrophysiologic changes due to vasospasm (VS) after subarachnoid hemorrhage (SAH) is a necessity for in-time and adequate therapeutic management. The aim of the present case report is to describe and demonstrate the results of transcranial Doppler (TCD) monitoring and brainstem auditory evoked potentials (BAEPs) examination, which indicate the development of combined circulatory insufficiency in two vascular systems. On the 14th day after SAH, TCD showed accelerated velocities in the territory of middle cerebral artery (MCA) and basilar artery (BA). BAEPs, after ipsilateral stimulation, performed on the same day verified changes of potentials on the left side with abnormal I/V amplitude ratio. These results were suggestive of brainstem dysfunction. The CT examination of the next day revealed infarction in the posterior parietal borderline zone of the left hemisphere. The patient had clinical signs of sensory aphasia, which resolved completely after one-week treatment with nimodipine.
