Cerebellar cerebral infarction can be considered to have passed the danger period after 7 days if the area of cerebellar cerebral infarction is small; if the infarction area is large, it takes 2 weeks to pass the danger period.
After acute cerebral infarction, due to the blockage of cerebral blood flow, ischemia and necrosis will occur in the surrounding tissues, causing brain cell edema. Cerebral infarction onset 24 hours of brain cells can appear swelling, 3 ~ 7 days for the peak of edema, but also the dangerous period of cerebral infarction, because cerebral edema will compress the brain tissue to cause damage, serious cases can endanger the patient’s life.
If the cerebellar infarction area is small, the cerebral edema will be relatively light, and the edema will basically subside after 7 days, and the condition will be stable and the patient will pass through the dangerous period; if the cerebellar infarction area is large, the resulting cerebral edema will compress the brainstem or the quadriventricle in severe cases, affecting the circulation of the cerebrospinal fluid, and respiratory and cardiac arrests will occur, so the dangerous period is relatively long, and it may take up to 2 weeks.
If patients are diagnosed with cerebellar infarction, they should actively cooperate with doctors to carry out standardized treatment to avoid adverse consequences.
