Brain death criteria from 24 countries. A recent study (30) revealed as many different brain death legislations as countries sampled. Data adapted with permission from (30). A few criteria that deviate from most countries are highlighted (somewhat arbitrarily) in bold and italics, e.g., up to 6 physicians are required to take part in a brain death protocol in South Korea but only 1 in Sweden. 4-VA, four vessel angiography; CAG, cerebral angiography; CTA, computed tomography angiography; DSA, digital subtraction angiography; EEG, electroencephalography; HMPAO, hexa-methyl-propylene-amine oxime; MEP, motor evoked potential; MRA, magnetic resonance imaging angiography; MRI, magnetic resonance imaging; SLSEP, short-latency somatosensory evoked potential; SPECT, Single-photon emission computed tomography; TCD, transcranial doppler; wb, guidelines follow the concept of whole brain death (in contrast to brainstem death as in the UK and India).
