Sažetak
Learning Objectives: To use transcranial Doppler sonography to confirm brain death. Background: Brain death is a clinical diagnosis. Transcranial Doppler sonography is a non-invasive bedside confirmatory test Imaging Findings or Procedure Details: After examination by two experienced examiners, if a coma patient with established cause of coma, sufficient to account for permanent loss of brain function and excluding other confounders, shows no evidence of cerebral and brain stem function, transcranial Doppler sonography can be performed. Ventricular drains or large openings of the skull possibly interfering with the development of the intracranial pressure must be absent. During the examination, blood pressure should be monitored and documented, and hypotension (systolic BP , 100 mmHg) should be avoided. Cerebral circulatory arrest can be confirmed if the extra- and intracranial Dopplersonographic findings have been recorded and documented both intraand extracranially and bilaterally on two examinations at an interval of at least 30 min: systolic spikes or oscillating flow in any cerebral artery which are recorded by bilateral transcranial insonation for anterior circulation, and any intracranial vertebral or basilar artery which is recorded by sub-occipital insonation for the posterior circulation. The diagnosis established by the intracranial examination must be confirmed by the extracranial bilateral recording of the common carotid arteries, internal carotid arteries and vertebral arteries. Conclusion: Transcranial sonography is an easy bedside test for the assessment of cerebral circulatory arrest.
