Ultrasound Non-invasive Measurement of Intracranial Pressure in Neurointensive Care

Ultrasound Non-invasive Measurement of Intracranial Pressure in Neurointensive Care

Of the studied ultrasound nICP methods, ONSD is the best estimator of Intracranial Pressure (ICP). The novel combination of ONSD ultrasonography and vTCD of the straight sinus is a promising and easily available technique for identifying critically ill patients with intracranial hypertension. This was a prospective, single-cohort observational study of patients admitted to a tertiary neurocritical care unit. Patients with brain injury requiring invasive ICP monitoring were considered for inclusion. nICP was assessed using optic nerve sheath diameter (ONSD), venous transcranial Doppler (vTCD) of straight sinus systolic flow velocity (FVsv), and methods derived from arterial transcranial Doppler (aTCD) on the middle cerebral artery (MCA): MCA pulsatility index (PIa) and an estimator based on diastolic flow velocity (FVd).
