1.Craniotomy to remove the hematoma: It can completely remove the hematoma under direct vision and achieve the purpose of immediate decompression. In case of active bleeding, it can completely stop the bleeding. If the preoperative condition is serious, cerebral edema is obvious, and the decrease of intracranial pressure is not obvious at the end of the operation, it is possible to perform decompression by debridement at the same time and leave a drainage tube in the hematoma cavity to smoothly pass the postoperative reaction period. Therefore, craniotomy is mostly used for patients who have not deep hemorrhage, large hemorrhage, severe midline shift, preoperative grade II or above and existing brain herniation formation but for a short period of time. This method is also applied to cerebellar hemorrhage in order to achieve rapid decompression. 2.Ventricular drainage: The ventricles have the function of promoting blood absorption, and small amount of ventricular hemorrhage can be absorbed by itself without surgery. When intraventricular hemorrhage blocks the cerebrospinal fluid pathway and causes an increase in intracranial pressure, ventricular drainage is needed in a timely manner. 3.Puncture aspiration and drainage: The puncture needle or suction tube is accurately placed in the center of the hematoma through the cranial borehole, which can prevent damage to the surrounding tissues when aspirating the hematoma. For the blood clot that cannot be easily aspirated, drugs that can dissolve the blood clot (such as urokinase, tissue fibrinogen activating factor, etc.) can be injected to liquefy the hematoma, or mechanical devices (such as spiral devices, high-pressure water jets or ultrasonic waves, etc.) can be used to break up the hematoma and facilitate aspiration. A silicone tube with a diameter of 3 mm (10F) can also be left in the hematoma cavity for continuous drainage of the hematoma. When the amount of bleeding is not too large, if 60%-70% of the total bleeding can be removed by the first puncture, the intracranial pressure and cerebral pressure can be relieved to avoid excessive fluctuation of intracranial pressure and rapid midline repositioning of the epidural or subdural hematoma. The puncture aspiration method is suitable for hemorrhage in all parts, especially deep hemorrhage, such as thalamic hemorrhage, brain parenchymal hemorrhage with ventricular hemorrhage. The disadvantage of this method is that it cannot stop bleeding and there is a risk of rebleeding, and it is not suitable for those with large bleeding volume and progressive exacerbation of the disease. If the operation is late (>24 hours), the hematoma has formed a stronger blood clot, and the treatment of this method has failed, it should be promptly changed to open hematoma removal; if the residual hematoma is large and the original puncture needle cannot be reached, it is recommended to perform another puncture and perform counter-oral drainage according to the CT results. After 24 hours of minimally invasive surgery, the hematoma removal is not very satisfactory, and after CT review, it is found that although the puncture needle is in the hematoma cavity, it is biased to one side, or at the edge of the hematoma. First, the direction of the lateral hole of the puncture needle can be adjusted so that the lateral hole is aligned with the direction of the main body of the hematoma, and at the same time, the concentration of the clot liquefying agent and the number of times of removal can be increased, and most of them can achieve the therapeutic purpose. Where this treatment still does not solve the problem, only then can an additional minimally invasive needle be used.
