Transcranial Doppler [PDF]

Journal of Neuroanaesthesiology and Critical Care, 2015
Transcranial Doppler (TCD) is a bedside, non-invasive, reproducible, non-expensive neuromonitoring device which can be used in many clinical scenarios. Based on the principle of the Doppler shift, blood flow velocity (FV) in the cerebral vessels can be ...

Variations in transcranial doppler among pediatric patients with sickle cell disease in the Brazilian Northeast: a cross-sectional study [PDF]

Hematology, Transfusion and Cell Therapy
Background: Stroke, the most severe neurological complication of sickle cell disease, can result in irreversible sequelae and death. Transcranial Doppler combined with periodic blood transfusions reduces the chances of stroke by 90 %.

How I use Transcranial Doppler

Critical Care, 2019
Transcranial Doppler (TCD) is a bedside, low-cost, and non-invasive technique able to evaluate cerebral hemodynamics [1]; the implementation of transcranial color-coded duplex sonography (TCCS) aids in evaluating the brain anatomy and intracranial ...

Effect of optimal operator positioning on transcranial Doppler acquisition: a randomized controlled trial [PDF]

Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine
Background Ergonomic conditions during ultrasound procedures may influence both acquisition time and image quality. In transcranial Doppler, positioning at the patient’s head could improve operator comfort and performance.

Comparison of Unilateral Middle Cerebral Artery and Bilateral Middle Cerebral Artery Monitoring for Right-to-Left Shunt Detection by Contrast-Enhanced Transcranial Doppler

Frontiers in Neurology, 2022
IntroductionContrast-enhanced transcranial Doppler (c-TCD) is a noninvasive test with high sensitivity for the detection of a right-to-left shunt (RLS). Currently, there are no reports on the outcomes of unilateral versus bilateral middle cerebral artery

Transcranial Doppler as a screening test to exclude intracranial hypertension in brain-injured patients: the IMPRESSIT-2 prospective multicenter international study

Critical Care, 2022
Background Alternative noninvasive methods capable of excluding intracranial hypertension through use of transcranial Doppler (ICP tcd ) in situations where invasive methods cannot be used or are not available would be useful during the management of ...
