The severity of subacute cerebral infarction in the pontine brain is related to the location, size, and number of infarcts. The condition of some patients is more serious. In normal human physiological anatomy, the pontine brain is connected to the midbrain above and the medulla oblongata below. There are many fiber bundles associated with the cerebral cortex traveling in the pontine brain, and some nuclei of cerebral nerves traveling. Although subacute infarction in the pontine brain is not as acute as acute cerebral infarction, it may have serious consequences if the infarction is adjacent to important structures, is large, and has a large number of infarcts. Damage to the medulla oblongata may cause respiratory and cardiac arrest, which can be life-threatening in a short period of time; damage to the pyramidal tract, sensory conduction fibers, and cerebral nerves may cause cross paralysis and sensory impairment; damage to the reticular activating system may also cause coma of varying degrees, and so on. Therefore, patients with subacute cerebral infarction in the pontine brain need to actively cooperate with physicians for treatment, and actively carry out rehabilitation training, so as to obtain a better prognosis as far as possible.
