Acute hemorrhagic infarction of brain
Hemorrhagic infarct - Wikipedia
Acute Subarachnoid Hemorrhage at the Base of the Brain Some believe extensive bleeding into the cisterns at the base of the brain is a separate distinct type of subarachnoid hemorrhage. In their gross appearance they are very similar in appearance to the acute subarachnoid hemorrhage occurring at the base of the brain due to rupture of an ...

If the cessation of flow lasts for more than a few minutes, infarction or death of brain tissue results. Stroke has occurred if the neurologic signs and symptoms last for 24 h. A generalized reduction in cerebral blood flow due to systemic hypotension (e.g., cardiac arrhythmia, myocardial infarction, or hemorrhagic shock) usually produces ...

Acute ischemic and hemorrhagic CVA’s have been shown to adversely effect cerebral autoregulation and make the brain more vulnerable to decreases in BP. One way the brain protects itself is by a reflex increase in MAP that will counteract any decrease in CPP when ICP increases.

Intracerebral hemorrhage is defined as non-traumatic abrupt onset of severe headache, altered level of consciousness and/or focal neurologic deficit that is associated with a focal collection of blood within the brain parenchyma on imaging or at autopsy and is not due to trauma or hemorrhagic conversion of a cerebral infarction.

Third, the fetal brain has a higher water content that increases its mass and allows if to develop more momentum when acceleration is applied. These unique conditions could make the fetus more susceptible to developing subdural hematomas without obvious trauma. The type of hemorrhagic lesion a fetus will show depends greatly on their maturity.
