Cerebral ischaemic stroke due to global hypoperfusion with watershed infarct
Acidente vascular cerebral isquêmico devido à hipoperfusão global com infarto em zona de fronteira
CategoryDefinition
This is a sudden loss of brain function due to a lack of adequate blood flow. It occurs in association with a low state of blood flow to the brain. The "watershed" regions of the brain, regions that are supplied by the branching ends of two large arteries, are particularly sensitive to low oxygen supply when arteries do not maintain the appropriate tension.
Coding Note
If an additional code is used for anatomy, the artery affected by the stroke should be selected.
