External Ventricular Drains versus Intraparenchymal Intracranial Pressure Monitors in Traumatic Brain Injury: A Prospective Observational Study.
Intracranial pressure (ICP) monitoring is the standard of care for patients with traumatic brain injury (TBI) and is used frequently. However, the efficacy of treatment based on the type of ICP monitor used for improving patient outcome has not been assessed prospectively. This study explores whether the type of ICP monitoring device used affects the neurologic outcomes of patients with TBI. ⋯ Device selection for ICP monitoring provides prognostic discrimination, and use of EVDs may have a bigger advantage in controlling refractory intracranial hypertension. Based on our findings, we recommend routine placement of an EVD in patients with TBI, unless only parenchymal-type monitoring is available.

A challenging step of the paramedian supracerebellar-transtentorial approach is to expose the anterior portion of the mediobasal-temporal region (MTR), a step that seems most affected by the steepness of the tentorium. The objective of this study was to define magnetic resonance imaging measurements that can predict the level of challenge in exposing the anterior portion of the MTR. ⋯ The results provide strong evidence proving that the lesser the tentorial and occipital angles, the easier the exposure of the anterior portion of the MTR during the paramedian supracerebellar-transtentorial approach. The tendency of the cranial shape toward dolichocephaly seems to have the same practical value in choosing the approach. It is easier to expose the anterior portion of the MTR in these individuals.
