Brazilian Guidelines for transcranial doppler in children and adolescents with sickle cell disease

Revista Brasileira de Hematologia e Hemoterapia, 2011
BACKGROUND: Sickle cell disease is the most common monogenic hereditary disease in Brazil. Although strokes are one of the main causes of morbidity and mortality in these patients, the use of transcranial Doppler to identify children at risk is not ...

Monitoring cerebral vasospasm: How much can we rely on transcranial Doppler

Journal of Anaesthesiology Clinical Pharmacology, 2019
Cerebral vasospasm leading to delayed cerebral ischaemia is one of the major concerns following subarachnoid haemorrhage (SAH). Various modalities are present for evaluation and detection of cerebral vasospasm that occurs following SAH.

Transcranial Doppler. [PDF]

Stroke, 1988
TCD recording of flow velocities in intracranial vessels was first described by Aaslid in 1982. The utility of this instrument becomes more apparent as it is used in different clinical settings and compared with angiographic findings (Figures 1 and 2).

Perioperative stroke during carotid endarterectomy: benefits of multimodal neuromonitoring - a case report

BMC Neurology, 2022
Background Carotid endarterectomy is routinely performed after ischemic stroke due to carotid stenosis. Perioperative, cerebral blood flow and oxygenation can be monitored in different ways, but there is no clear evidence of a gold standard and a uniform

Cerebral artery dilatation maintains cerebral oxygenation at extreme altitude and in acute hypoxia : an ultrasound and MRI study [PDF]

, 2011
Transcranial Doppler is a widely used noninvasive technique for assessing cerebral artery blood flow. All previous high altitude studies assessing cerebral blood flow (CBF) in the field that have used Doppler to measure arterial blood velocity have ...
