Transcranial Sonography and Cerebral Circulatory Arrest in Adults: A Comprehensive Review

Figure 4

Although diastolic flow is absent, basilar artery shows anterograde systolic spikes with peak intensity higher than 50 cm/sec and a wide peak width in a 54-year-old male with severe brain injury. The clinical examination showed a preserved response to the apnea test. Therefore, this pattern was not compatible with cerebral circulatory arrest.
