Resumen

La Ultrasonografía Doppler Transcraneal (DTC) es una técnica no invasiva, que al emplear ondas sonoras de baja frecuencia (2MHz) nos permite atravesar la barrera craneal y poder estudiar la velocidad de la sangre en las principales arterias cerebrales, velocidad que guarda relación directa con el flujo cerebral y es inversamente proporcional al calibre del vaso estudiado.

Presentamos una revisión sobre la metodología del DTC, sus valores normales, los diferentes parámetros que influyen en los registros, concluyendo con una revisión sobre sus principales indicaciones en Neurocirugía, fundamentalmente en el estudio del flujo cerebral postraumático y del vasoespasmo secundario a la hemorragia subaracnoidea.

Palabras clave:
Doppler transcraneal
Hemorragia subaracnoidea

Traumatismo craneoencefálico
Vasoespasmo
Summary

Transcranial Doppler sonography (TCD) is a widely noninvasive method of monitoring real-time changes of blood flow signals in central nervous system disorders.

Flow velocity is proportional to the volume of cerebral blood flow and inversely related to the cross-sectional area of the insonated vessel.

The object of this study is to describe the basic methodology, the indications and limitations of transcranial Doppler and the indications in craniocerebral injuries and for the detection of vasospasm following subarachnoid hemorrhage.

Key words:
Head injuries
Hydrocephalus
Intracranial pressure
Subarachnoid hemorrhage
Transcranial Doppler ultrasound
Vasoespasm
