1.Neuroendoscopy for hypertensive cerebral hemorrhage: Its advantage is that the surgical operation is completed under direct vision, which can effectively stop the bleeding and avoid the blindness and unnecessary damage of surgical operation. Its limitation is that the operative field is limited, it is not easy to control larger bleeding, and it is more difficult to deal with large hematoma. 2.Neuronavigation-assisted minimally invasive surgery for hypertensive cerebral hemorrhage: compared with traditional stereotactic, its characteristics are: ① no need to install the head frame, which can reduce the moving of the patient and save the operation time; ② change the non-visible target into a visual target, easy to operate, accurate positioning of the hematoma, and can minimize the medical source of injury. 3. Stereotactic hematoma removal: this procedure can directly locate the target point and improve the accuracy of puncture. However, there is the defect that simple puncture aspiration and drainage cannot sufficiently aspirate the hematoma. Even though means to increase hematoma evacuation such as Archimedes’ drill and high-pressure flushing have been generated, they require special equipment, are more complicated to operate, more invasive, and have longer operation time, and are not suitable for emergency treatment of patients with ICH. 4.Intracerebral hematoma removal under CT + urokinase drainage: At present, the relatively perfect technique for minimally invasive treatment of cerebral hemorrhage in China is the directional placement of hose intracerebral hematoma suction removal under CT proposed by Professor Sun Shujie of the Dongfang Hospital of Tongji University. This technique is a combination of 3D head positioning and CT. Using this method to study on a human skull model, the results showed that the error value of target point localization in the center of the hematoma was less than 5 mm, which achieved the purpose of preoperative precise localization of intracerebral hematoma. With accurate preoperative localization and intraoperative CT surveillance, this technique can perform multi-target and multi-path surgery for large hematomas, achieving the goal of removing only the intracerebral hematoma without injuring the normal brain tissue surrounding the hematoma.
