The probability of recurrence after a caval infarction is high and may not recur with active prevention. However, the recurrence rate is related to the patient’s physical state and cannot be generalized. Cavitary infarction is called lacunar cerebral infarction, ischemic micro-infarction of atherosclerosis of the deep penetrating branch of the brain, belonging to a kind of relatively mild cerebral infarction, with mild symptoms, often manifested as simple motor or sensory abnormalities or even no obvious symptoms, often on the basis of hypertension, diabetes and other diseases. Considering that patients have underlying diseases such as hypertension and diabetes, there is still a high possibility of recurrent cerebral infarction if blood pressure and blood sugar are not well controlled. In addition to hypertension and diabetes mellitus, hyperlipidemia, obesity, cardiac arrhythmia, and familial heredity are all high risk factors for cerebral infarction, so people with these factors should actively treat the underlying diseases, and some patients may need long-term medication. If cavernous cerebral infarction is diagnosed, please follow the doctor’s instructions for treatment.
