The criteria for the confirmation of brain death (BD) using transcranial Doppler
ultrasonography (TCD) state that flow should not be observed in the internal carotid artery …

Abstract Background Transcranial Doppler (TCD) ultrasonography to demonstrate cerebral
circulatory arrest (CCA) is a confirmatory test for brain death (BD). The primary aim of this …

Abstract Introduction Transcranial Doppler (TCD) can detect the cerebral circulation arrest
(CCA) in brain death. TCD is highly specific, but less sensitive because of false-negatives …

The interpretation of clinical tests for brain death is often complicated by the presence of
facial trauma, or the use of barbiturate therapy for reduction of intracranial pressure. We …

Background and purpose: Diagnosis of brain death requires confirmation of the clinical
diagnosis by appropriate tests, generally electroencephalography (EEG) and angiography …

OBJECTIVE: Cerebral blood flow tests have increasingly been advocated for the
confirmation of brain death (BD). Angiography has been considered the gold standard in the …

OBJECTIVE: Transcranial Doppler sonography (TCD) provides accurate confirmation of
cerebral circulatory arrest (CCA) in brain death (BD), but is not feasible in patients with …

Objective: To evaluate the validity of transcranial Doppler (TCD) in confirming brain death
from various pathological conditions. Methods: An observational case–control study over a …

Objective: To determine the clinical validity of transcranial Doppler ultrasonographic (TCD)
signs of total cerebral circulatory arrest for confirmation of brain death and to define the test …

Background. Although the clinical examination and documentation of the clinical signs of
brain death are very uniform, there are significant differences in the guidelines for using …
