Estimation of intracranial pressure by CT scan in closed head trauma.


The predictive values of certain features of computerized tomographic (CT) scans in estimating intracranial pressure (ICP) were investigated in 40 patients following closed head injuries. The various features of CT scans selected for study included ventricular compression, the size of the parenchymal mass lesion, midline shift, and an intraventricular clot. All patients with intraventricular clot exhibited severe elevation of pressure. Ventricular compression correlated well with the level of intracranial pressure. Size of the mass was found to be suggestive of pressure elevation but did not reach statistical significance. Midline shift showed no correlation with the intracranial pressure.
