Feasibility and Diagnostic Value of Transcranial Color‐Coded Duplex Ultrasound in Critically Ill Children: Case Series Report from Low‐Resource Settings

Transcranial color‐coded duplex (TCCD) ultrasound enables rapid bedside assessment of cerebral hemodynamics in pediatric intensive care units (PICUs), yet its use is underreported in resource‐limited settings. We retrospectively reviewed five pediatric cases from a single tertiary PICU in which TCCD was performed as part of neurocritical care, applying standardized protocols and operator training. Median mean flow velocity (MFV) increased from 70 to 98 cm/s post‐intervention, while pulsatility index (PI) decreased from 1.30 to 1.05. The cases demonstrated diagnostic contributions in suspected brain death, cerebral vasospasm, arteriovenous malformation, and raised intracranial pressure. These findings suggest that TCCD is a feasible, noninvasive neuromonitoring tool in pediatric neurocritical care, even in resource‐limited settings, although larger studies are needed to validate its diagnostic accuracy.
