Case of the Week: November 20, 2019

This is a case of a 52 yo F trauma patient with severe traumatic brain injury. She was intubated and transferred to the ICU where, given the severity of her TBI, an intraparenchymal ICP monitor was placed by neurosurgery. The ICP monitor was initially showing an ICP of 10. Overnight, however, despite no apparent clinical change, the ICP waveform was inconsistent and the readings were now showing values around 40-50. We thus performed a point-of-care TCD to help determine whether her ICP was truly elevated or whether the ICP monitor was giving spurious information. Have a look at the following images. Do you think the TCD spectral waveform is consistent with markedly elevated ICP?
