The annual incidence of cerebral hemorrhage in China is as high as 50.6/100,000~80.7/100,000. In recent years, with the acceleration of the aging process of the population and lifestyle changes, the incidence rate is increasing year by year, and the prognosis of acute onset is poor and medical costs are high, which seriously endangers health and quality of life, and is a formidable clinical and social public health problem. Hypertensive cerebral hemorrhage is a primary hemorrhagic disease in the brain parenchyma secondary to hypertension, with high morbidity, high mortality and high disability. The current treatment of hypertensive cerebral hemorrhage includes conservative treatment, open cranial hematoma removal, microsurgical removal with small bone windows, stereotactic hematoma drainage, neuroendoscopic hematoma removal, hard or soft channel hematoma drainage and combined with extraventricular drainage. The large bone flap craniotomy can remove deep hematoma under direct vision and stop bleeding reliably; at the same time, it can decompress the bone flap, but it requires general anesthesia and causes irreversible damage to important structures around bleeding, and the operation is traumatic, long, bleeding, heavy postoperative edema reaction, prone to postoperative complications, and has a high patient mortality rate. The small bone window craniotomy, also known as neurosurgical “lock-hole” surgery, is a safe and reliable way to remove blood clots and precisely reveal and control bleeding points under microsurgical techniques according to the characteristics of the lesion, resulting in less damage to brain tissue. Although operating under a microscope, it is also a relatively large damage to the brain tissue and organism, and this damage largely offsets its advantage of more thorough removal of the hematoma. The use of minimally invasive techniques for the treatment of cerebral hemorrhage accelerates the speed of hematoma removal, reduces intracranial pressure, significantly reduces the pressure of the hematoma on brain tissue and the toxic effects of degradation products on brain tissue, further reduces cerebral edema and neurological impairment, thus improving the success rate of salvage and reducing the morbidity, mortality and disability of patients, and is also generally accepted. Neuroendoscopic hematoma removal is less invasive, has fewer complications, and facilitates functional recovery. The operation is intuitive, so that aspiration of the hematoma can be strictly controlled in the center of the hematoma, and bleeding can be detected and stopped in a timely manner. The disadvantage is that the operative field is limited, and the intraoperative endoscopic operating channel is only through one surgical instrument, which is not easy to control larger bleeding and more difficult to deal with large hematomas. Because of the expensive equipment, and not many medical units carry out endoscopic technology. Minimally invasive hematoma crushing and aspiration is the use of YL-1 intracranial hematoma crushing and puncture needle and thrombolytic drugs to aspirate, liquefy and drain intracranial hematomas for the purpose of removing them. This method is simple and fast, and can be done by simple localization puncture with the imaging data provided by CT and anatomical markings on the brain surface. It can quickly establish a hard channel for hematoma removal and is fixed on the skull, with better stability and confinement. However, its shortcomings are that it cannot be operated under direct vision, the removal of hematoma is not complete, it cannot effectively stop bleeding, the diameter of the drainage tube is small, and the positioning of freehand puncture is not accurate. CT-guided or stereotactic hematoma placement and drainage: The application of stereotactic technique for sub-total evacuation of intracranial hematoma was first reported in 1978, and this method is a minimally invasive hematoma removal procedure, with the help of CT and MRI guidance, the puncture needle or suction tube can be accurately placed in the center of the hematoma. injection to facilitate postoperative drainage. It is an accurate localization, less invasive, convenient, fast, safe and effective microinvasive treatment method. Stereotactic puncture and drainage can directly reduce the mechanical compression of the hematoma on the brain tissue, reduce the release of inflammatory mediators, and reduce secondary brain injury such as cerebral edema, but stereotactic hematoma drainage surgery is limited in clinical application, especially in the majority of primary hospitals, because of the large and complex equipment and long operation time. Frameless stereotactic techniques represent a new development trend and have gradually become a new hot spot for research and application. Especially in recent years, the minimally invasive drainage technique of soft channel has been popularized and applied. The timely elimination of the hematoma is conducive to reducing the damage of surrounding tissues and structures and preventing hydrocephalus, and it is the most suitable technique for hematoma removal of cerebral hemorrhage due to small trauma, simple and rapid, and good efficacy, and it is adapted to China’s national conditions. At present, the neurosurgery department of Huzhou Central Hospital has routinely carried out soft channel minimally invasive intracranial hematoma drainage. Soft-channel minimally invasive hematoma drainage can increase the survival rate and improve the quality of life of patients. The procedure has a short preparation time, can be performed under local anesthesia, has a short surgical operation time, can quickly remove part of the hematoma and relieve the pressure on the brain tissue around the lesion, and has few postoperative complications. This minimally invasive technique has become one of the characteristic treatment items of the neurosurgery department of Huzhou Central Hospital.
