1.Cranial hematoma removal can be divided into bone flap craniotomy and bone window craniotomy. The former is mostly used for hematoma volume, serious midline displacement, preoperative consciousness impairment, and brain herniation formation but for a short period of time; the latter is used for small and moderate amount of less superficial bleeding, with the characteristics of fast surgery and easy to tolerate by patients with local anesthesia. 2.Cone or borehole hematoma drainage According to the unit of hematoma, choose the closest to the hematoma and avoid the important functional area to perform skull borehole or cone hole. The fluid component of the hematoma is extracted by puncture with a brain needle, and then a catheter with a lateral hole at the head is placed for continuous drainage. (This method is more commonly used.) 3.Stereotactic hematoma removal The advantage of using stereotactic technique to remove hematoma is to directly improve the accuracy of puncture and reduce the damage to brain tissue, which is suitable for bleeding in various parts of the brain, especially for limited hematoma in the brainstem, thalamus and other important parts. 4.Endoscopic hematoma removal Because the endoscope has the advantages of direct vision, flushing and suction, it can remove the hematoma, and also can stop the bleeding under direct vision. Recently, it has been reported that hematoma removal from the nucleus accumbens and the thalamus is performed with the use of the endoscope and has achieved more satisfactory results. 5.Minimally invasive hematoma removal (i.e., shampoo formerly known as) uses laser technology to place a drill needle directly into the hematoma cavity under the guidance of CT using the principle of biofluid mechanics, and crush, flush, dissolve, separate and attract the hematoma through the drill needle and the hematoma liquefying agent. 6.Ventricular drainage is suitable for thalamic hemorrhage, deep brain hemorrhage into the ventricle, according to the hemorrhage situation, one or bilateral lateral ventricular drainage, and can inject urokinase through the drainage tube to dissolve the blood clot, continuous drainage for several days, review, and generally 5-7 days to withdraw the tube.
