In recent time, due to the change of seasonal weather, the environmental temperature difference is large. Many elderly patients, especially those with previous history of hypertension, heart disease and diabetes, have come to our neurosurgery department with sudden cerebral hemorrhage. Due to the age mostly around 80 years old, the bleeding volume is large, the cumulative effect of general anesthesia craniotomy on multiple organs of the whole body is large, and the prognosis is poor, mostly combined with intra-pulmonary infection, multi-organ dysfunction of respiration and circulation after surgery, and the mortality and disability rate is high. According to this situation, we adopt minimally invasive hematoma aspiration, and the results are relatively satisfactory. When it comes to minimally invasive, we all know that it is a kind of surgery with small incisions and trauma. To what extent is it small? Recently, our neurosurgery department locates the hematoma in three dimensions under CT, then uses a ball-point pencil-thin thrombolytic aspiration needle and drainage tube to enter the hematoma cavity, injects a rapid thrombolytic drug or a rinse solution with heparin and other drugs in proportion, and externally connects a disposable extracranial drain after aspiration, and often the hematoma is basically cleared in about three days, with a better prognosis. Especially for hemorrhage in the left dominant hemisphere of the brain, craniotomy often has to go through the normal cerebral cortex to enter the hematoma cavity and remove the hematoma, which causes more damage than minimally invasive surgery, and there are more chances of aphasia and contralateral limb paralysis, so this stereotactic hematoma lysis aspiration and drainage is adopted for patients without brain herniation after a short period of time to control blood pressure and blood sugar, regulate heart function, and have relatively stable vital signs. The results are very good. Stereotactic hematoma lysis aspiration and drainage has many benefits, such as less risk, less trauma, less expense, and good prognosis, which are easily accepted by patients and their families. However, accurate calculation and stereotactic positioning techniques, skilled puncture and gentle aspiration techniques are required, otherwise it is like hitting a target that cannot hit the ten rings, that is, it cannot enter the hematoma cavity accurately, which leads to treatment failure or rebleeding.
