Transcranial Doppler ultrasonography in the determination of brain death
Neurosurgery, 1989Abstract Transcranial Doppler (TCD) ultrasonography was used to perform multiple examinations of 24 patients who sustained cranial injuries, 23 of whom progressed to death. In the 20 of these 23 patients for whom an adequate TCD signal could be obtained, a characteristic reverberating wave form pattern was observed, with an associated ...

Transcranial Doppler Ultrasonography
2019Abstract 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

Transcranial Doppler Ultrasonography With Induction of Anesthesia for Neurosurgery
Journal of Neurosurgical Anesthesiology, 1994Intracranial hypertension can occur with induction of anesthesia; however, the clinical significance of this is unclear. We used transcranial Doppler (TCD) ultrasonography in neurosurgical patients during induction of anesthesia and endotracheal intubation to assess the incidence of high intracranial pressure (ICP) waveforms and to correlate TCD ...

Principles of Transcranial Doppler Ultrasonography
2020Transcranial 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.

Role of Transcranial Doppler Ultrasonography in Cerebrovascular Disease
Recent Patents on CNS Drug Discovery, 2010Transcranial Doppler ultrasonography (TCD) is the only non-invasive examination that provides a reliable evaluation of intracranial blood flow patterns in real-time, adding physiological information to the anatomical information obtained from other neuroimaging modalities. TCD is relatively cheap, can be performed bedside, and allows monitoring both in

Transcranial colour Doppler ultrasonography
Rivista di Neuroradiologia, 2001Transcranial 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.

Vascular Dizziness and Transcranial Doppler Ultrasonography
Annals of Otology, Rhinology & Laryngology, 1989Dizziness 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 ...

Transcranial Doppler ultrasonography in patients with Moyamoya disease
Clinical Neurology and Neurosurgery, 1997This study included 17 patients (five men and 12 women) with clinical diagnosis of Moyamoya disease from conventional angiograms. Bilateral basal arteries were measured by the transtemporal approach with a 2 MHz pulsed Doppler instrument (TC-2 64B EME). In 28 out of the 34 basal arteries (82.4%), reliable recordings were obtained.

Comparison of Duplex and Nonduplex Transcranial Doppler Ultrasonography
Ultrasound Quarterly, 2008Transcranial Doppler ultrasonography is essential in the management of children with sickle cell anemia and is a valuable adjunct to the evaluation of a variety of intracranial pathologies in children and adults, including vasoconstriction caused by subarachnoid hemorrhage, demonstration of major intracranial vessel stenoses or occlusion, determination
