“…In a series of 37 consecutive patients with Glasgow coma scale scores < 7, the specificity was 100% and the sensitivity was over 90%. 34 False positives have been reported in some series in 10-15%. 35 Transcranial Doppler showed no flow in the vertebrobasilar system, yet scintigraphic techniques and selective angiography revealed arterial perfusion.…”

“…The initial reports of TCD for BD diagnosis were published in 1987 19,20 . Over the past 20 years, numerous studies have attempted to validate neurosonography 4,5,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] , and the two most important were conducted by Hassler, Steinmetz, Pirschel and Gawlowski 5,21 and Petty et al 4 .…”

Neurosonological studies, specifically transcranial Doppler (TCD) and transcranial color-coded duplex (TCCD), have high level of specificity and sensitivity and they are used as complementary tests for the diagnosis of brain death (BD). A group of experts, from the Neurosonology Department of the Brazilian Academy of Neurology, created a task force to determine the criteria for the following aspects of diagnosing BD in Brazil: the reliability of TCD methodology; the reliability of TCCD methodology; neurosonology training and skills; the diagnosis of encephalic circulatory arrest; and exam documentation for BD. The results of this meeting are presented in the current paper.Key words: transcranial Doppler, encephalic circulatory arrest, brain death. resumo Estudos neurossonológicos, especialmente o Doppler transcraniano (DTC) e o duplex transcraniano codificado a cores (DTCC), apresentam elevados níveis de especificidade e sensibilidade quando utilizados como exames complementares no diagnóstico de morte encefálica (ME). Um grupo de peritos do Departamento Científico de Doppler transcraniano da Academia Brasileira de Neurologia criou uma força-tarefa de forma a determinar os critérios neurossonológicos para os seguintes aspectos no diagnóstico de ME no Brasil: metodologia do DTC; metodologia do DTCC; treinamento e habilidades em Neurossonologia; diagnóstico de parada circulatória encefálica e documentação do exame para a ME. Os resultados deste encontro foram apresentados neste artigo.Palavras-Chave: Doppler transcraniano, parada circulatória encefálica, morte encefálica.

“…Diagnosis of brain death rests both on clinical criteria and confirmatory tests. In recent years, TCD has shown high sensitivity and specificity for determination of brain death in adults and children [51][52][53][54]. The proximal part of both MCA, and the basilar artery, are monitored at intervals.…”

Transcranial Doppler US, a non-invasive tool for evaluating the cerebral arteries, has evolved significantly during the last two decades. This review describes the practical procedure, and summarises and illustrates its established and "work-in-progress" indications in children. Indications for a transcranial Doppler US examination include, but are not limited to: (1) evaluation of cerebral blood flow velocities in the circle of Willis in patients with sickle cell anaemia to guide transfusion therapy; (2) diagnosis and follow-up of vasculopathy, such as moyamoya disease; (3) diagnosis and monitoring of acute cerebrovascular disorders in intensive care patients, in particular following traumatic brain injury, and during cardiovascular surgery; and (4) confirmation of a clinical diagnosis of brain death by documentation of cerebral circulatory arrest.
