Transcranial doppler ultrasonography

Journal of neurology, neurosurgery, and psychiatry
Abstract Transcranial Doppler ultrasonography (TCD) is a noninvasive, bedside procedure that can detect blood flow in the proximal cerebral intracranial arteries. TCD has multiple applications, including rapid assessment of anterior circulation blood flow in acute, large-vessel occlusion. For patients with subarachnoid hemorrhage, trends

Intraoperative Use of Transcranial Doppler Ultrasonography

Neurosurgery Clinics of North America, 1996
Transcranial Doppler (TCD) ultrasonography is a diagnostic tool that is well established in the fields of neurology and neurosurgery. There are many potential applications of TCD ultrasonographic monitoring in the perioperative care of the patient at risk of cerebral ischemia, the most important of which are detailed in this article.

Transcranial Doppler ultrasonography in intensive care

European Journal of Anaesthesiology, 2008
Transcranial Doppler is an innovative, flexible, accessible tool for the bedside monitoring of static and dynamic cerebral flow and treatment response. Introduced by Rune Aaslid in 1982, it has become indispensable in clinical practice. The main obstacle to ultrasound penetration of the skull is bone. Low frequencies, 1-2 MHz, reduce the attenuation of

Transcranial colour Doppler ultrasonography

Rivista di Neuroradiologia, 2001
Transcranial colour Doppler ultrasonography (TCCD), being a non-invasive method is an invaluable source of information on cerebral haemodynamics. It is the blood flow disturbances that often lead to irreversible ischemic lesions, which can then be detected a posteriori with various imaging techniques.

Transcranial Doppler Ultrasonography

2019
Abstract Transcranial Doppler (TCD) ultrasonography is a diagnostic technology for ascertaining numerous physiologic and pathologic phenomena by monitoring the direction and velocity of blood flow in intracranial vasculature. It is a noninvasive, point-of-care diagnostic tool that provides continuous and reproducible bedside data without

Principles of Transcranial Doppler Ultrasonography

2020
Transcranial Doppler (TCD) ultrasonography is a non-invasive bedside tool applied to the assessment of cerebral blood flow haemodynamics in major intracranial arteries. TCD allows dynamic monitoring of vessel pulsatility, with a high temporal resolution, and it is relatively inexpensive, repeatable and portable.

Transcranial Doppler Ultrasonography: Clinical Applications in Cerebrovascular Disease

Mayo Clinic Proceedings, 1990
Transcranial Doppler ultrasonography was introduced in 1982 as a noninvasive procedure for assessment of the intracranial cerebral circulation. The lightweight and portable equipment used for transcranial Doppler examination facilitates its use in the bedside assessment of critically ill hospitalized patients and outpatients.

Vascular Dizziness and Transcranial Doppler Ultrasonography

Annals of Otology, Rhinology & Laryngology, 1989
Dizziness as defined herein will include an illusion of motion caused by various degrees of ischemia to the vestibular pathway or its interconnecting pathways. “Syndrome,” such as the lateral medullary syndrome, denotes a macroinfarct, while a microinfarct or an area of incomplete infarct (where there may develop an incomplete degeneration of the ...

The Value of Transcranial Doppler Ultrasonography in Craniosynostosis

Journal of Craniofacial Surgery, 1999
Some children with craniosynostosis demonstrate raised intracranial pressure (ICP), requiring surgical decompression. Conventional methods of measuring ICP in such children are invasive, expensive, and require expertise. Transcranial Doppler ultrasonography (TCD) is an alternative, useful means of assessing ICP qualitatively, and is noninvasive ...
