Hypertensive cerebellar hemorrhage accounts for about 10% of the total cerebral hemorrhage, with dangerous condition, many complications and high morbidity and mortality rate. Traditional treatment is: conservative treatment is used for hemorrhage less than 10 ml, and posterior cranial fossa craniotomy is generally used for more than 10 ml. Posterior cranial fossa craniotomy has a long preparation time and must be performed under general anesthesia. The soft tissues (muscles) of the collar are thicker, which results in large surgical damage, more bleeding, most of which require blood transfusion, and heavier brain tissue damage, and sometimes the patient cannot tolerate the surgery due to their physical condition (e.g., suffering from diabetes, advanced age). Minimally invasive surgery for cerebellar hemorrhage has the following advantages: 1) less surgical damage; 2) no need for general anesthesia, only local anesthesia; 3) short surgical time; 4) no need for blood transfusion; 5) no restriction on age and the presence of diabetes (because of short surgical time and less damage, the impact on patients is smaller); 6) low cost. Based on the above advantages, minimally invasive treatment of cerebral hemorrhage is easily accepted by patients and their families.
