Transcranial Color-Coded Sonography With Angle Correction As a Screening Tool for Raised Intracranial Pressure.

ABSTRACT:

Objectives

Transcranial Doppler (TCD) has been evaluated as a noninvasive intracranial pressure (ICP) assessment tool. Correction for insonation angle, a potential source of error, with transcranial color-coded sonography (TCCS) has not previously been reported while evaluating ICP with TCD. Our objective was to study the accuracy of TCCS for detection of ICP elevation, with and without the use of angle correction.

Design

Prospective study of diagnostic accuracy.

Setting

Academic neurocritical care unit.

Patients

Consecutive adults with invasive ICP monitors.

Interventions

Ultrasound assessment with TCCS.

Measurements and main results

End-diastolic velocity (EDV), time-averaged peak velocity (TAPV), and pulsatility index (PI) were measured in the
