OBJECTIVE: We sought to determine the utility of constrat-enhanced transcranial color
sonography (TCCS) in the diagnosis of cerebral circulatory arrest in cases of difficult …

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 …

Summary QUESTION UNDER STUDY: For the determination of brain death (BD) in potential
organ donors, confirmatory tests that show cessation of cerebral circulation are used in …

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 …

Transcranial color-coded sonography (TCCS) monitoring of severe brain injury patients may
reveal various pathological hemodynamic changes. According to changes in flow velocities …

Background. Cerebral blood flow (CBF) volume can be measured at bedside by color
duplex flowmetry of the extracranial cerebral arteries. In neurointensive care patients, we …

The diagnosis of brain death remains a clinical challenge for intensive care unit physicians.
Worldwide regulations in its diagnosis may differ, and the need of ancillary tests after a …

Purpose Brain death (BD) is defined as the irreversible destruction of all brain functions. It is
usually diagnosed through a clinical examination, but in certain circumstances, ancillary …

Background and purpose Computed tomographic‐angiography (CT‐A) is becoming more
accepted in detecting intracranial circulatory arrest in brain death (BD). An international …
