Background: Transcranial color duplex ultrasound (TCCD) is becoming an important tool for
cerebral monitoring of brain-injured patients. To date, TCCD reproducibility has been …

Introduction: The clinical criteria for brain death consist of the demonstration of the absence
of any clinical sign of encephalic activity. Confirmatory testing is usually not required for the …

Among the main causes for the relatively small number of organ donors, the delay in the
diagnosis of brain death plays a major role. This prospective study was designed to evaluate …

We aimed to determine whether optical methods based on bolus tracking of an optical
contrast agent are useful for the confirmation of cerebral circulation cessation in patients …

Persistent cerebral blood flow occasionally confounds confirmatory tests for brain death and
results in the anguish of delayed diagnosis, unnecessary use of expensive resources, and …

Reduced cerebral blood flow after severe head injury results in an increased risk of ischemic
brain damage. Blood flow should therefore be monitored with a simple, reliable method …

• The absence of cerebral blood flow is a valuable adjunct confirming clinical criteria of brain
death. However, current methods to confirm absent cerebral blood flow have problems that …

Introduction The standardized diagnostic criteria for computed tomographic angiography
(CTA) in diagnosis of brain death (BD) are not yet established. The aim of the study was to …

The effects of compromised cerebral hemodynamics on intracranial blood flow velocity
patterns (BFV) were studied by noninvasive transcranial Doppler sonography (TCD) …

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 …
