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.

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 ...

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 Doppler ultrasonography in the determination of brain death

Neurosurgery, 1989
Abstract 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 ...

The Rise and Fall of Transcranial Doppler Ultrasonography for the Diagnosis of Vasospasm in Aneurysmal Subarachnoid Hemorrhage.

Journal of Neurosurgical Anesthesiology, 2018
T Doppler (TCD) ultrasonography uses a pulsed Doppler transducer for assessment of intracerebral blood flow. It is a noninvasive, real-time bedside monitoring tool to measure arterial flow velocities.

Transcranial Doppler Ultrasonography With Induction of Anesthesia for Neurosurgery

Journal of Neurosurgical Anesthesiology, 1994
Intracranial 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 ...
