Bone flap decompression is often used as an acute surgical treatment for acute craniocerebral injury, stubborn intracranial hypertension after aneurysm rupture, hypertensive cerebral hemorrhage, cerebral hemispheric infarct swelling, stubborn high cranial pressure meningitis, benign high cranial pressure, etc. It has the effect of significantly reducing intracranial hypertension and is considered essential for preserving the life of patients with stubborn high cranial pressure. The purpose of this surgery can be said to be a “local” sacrifice of brain tissue in exchange for the “overall” survival of the patient’s life. However, the removal of bone flap brain decompression has the disadvantage of causing a variety of surgical complications, among which craniotomy site occurrence of brain bulge and hydrocephalus is not uncommon, with the role of causing secondary or continued brain damage, if not given early and proper treatment, on the one hand, has the effect of leading to vegetation or long-term coma, causing “lung infection” or “On the other hand, it also has the effect of causing necrosis of herniated brain tissue, and is often the “sacrifice” of functional brain areas, especially the brain motor areas that govern the voluntary activities of the upper and lower limbs on the opposite side. On the other hand, it also has the effect of causing necrosis of the herniated brain tissue and is often a “sacrifice” of the functional brain areas, especially the motor areas of the brain that govern the voluntary movement of the contralateral upper and lower limbs. Many of the patients who survived this surgery were clinically disabled for life, and the patients themselves were bedridden for years, unable to care for themselves, “worse off than dead”, and a permanent burden to their families. Now some doctors have also recognized this danger, but because they cannot use early treatment of hydrocephalus shunt and do nothing, they only use the treatment of intravenous infusion of mannitol or lumbar puncture to put some cerebrospinal fluid, the effect is not satisfactory. In recent years, we have conducted a lot of research in this area, and developed a series of unique treatment methods and techniques to determine the treatment policy or strategy for early or early correct intervention of hydrocephalus and hydrocephalus, to ensure nearly 100% of hydrocephalus shunts without infection and shunt obstruction complications of treatment results, and obtained a very good or can be said to be “magical “The actual efficacy of the treatment: 1. The majority of these hydrocephalus patients with “intractable fever”, “central fever”, “intractable pneumonia”, and severe “phlegm” through the oral cavity or through an incision in the trachea are completely cured within the same day or a few days of my specific treatment. These patients have been the subject of “intensive treatment” in ICUs (Intensive Care Units for Intensive Care Patients) in hospitals of all sizes. The discovery of this new “anti-infection” effect, which I specifically call “correcting cerebral vital sign abnormalities”, not only “eliminates” the need for high “special monitoring” in ICU wards for these patients. I would like to say that it has the effect of “correcting the abnormalities of cerebral vital signs”, which not only can “save” the high amount of “advanced” i.e. expensive antibiotic “anti-infection” treatment in the ICU ward under high “special supervision”, but also rely on “advanced equipment “2. the “sub-cryogenic treatment” that must pay high “special medical fees” and can also greatly improve the survival rate and greatly shorten the entire time of hospitalization. “vegetative” role in promoting awakening: many long-term patients with hydrocephalus, in my special treatment within a week, from a coma or “vegetative” state awakened, and even part of the patient also recovered to normal communication skills or most or completely back to normal human life and learning and working ability. 3. Some of the patients with intellectual disabilities have greatly improved their intellectual level after my treatment. The daughter of one such patient sends me a text message every Spring Festival to thank me, and the content of one of the messages reflects the real situation: “Thank you, Director Li, for saving my mother. Although she still can’t walk on the ground, she can communicate with us completely correctly. The happy feeling of having ‘mom’ to call every time I come home is something that no amount of money can buy. With Mom’s presence, there is a happy reunion of our family every Spring Festival”. In summarizing this aspect of the work, especially recognized the importance of the following aspects: 1, must pay attention to the removal of bone flap brain decompression after the brain bulge and hydrocephalus serious potential harm, should immediately take or seek to terminate or discontinue the correct treatment of its cause brain continued damage. 2, to understand the concept of “correct treatment”: the mechanism of complete eradication of brain bulge or hydrocephalus, rather than waiting for a long time after the occurrence of brain atrophy “natural recovery” of brain bulge, because by then the brain damage has reached a very serious degree. 3, to clarify the correct treatment of the concept of “early and early”, first of all, if the correct treatment is used in the late stage of brain expansion or hydrocephalus, it is equivalent to “small fire” has become a “large fire “If the correct treatment is used at the late stage of hydrocephalus or hydrocephalus, it is equivalent to a “small fire” that has become a “big fire”. “Early” means in the early stages of the patient’s brain bulge or hydrocephalus; “early” means that the doctor who has the ability to properly treat the patient with brain bulge or hydrocephalus comes to the correct diagnosis and immediately gives the correct treatment, even though the patient may The patient may not be in the early stages of the disease. 4. These diseases are currently found to be ineffective when treated with either ventriculoscopy or neuroendoscopy. Not only is ventriculoscopic or neuroendoscopic treatment ineffective, but special attention should be paid to its adverse effects of causing a significant increase in the rate of infection and shunt failure in subsequent shunts. In particular, choroid plexus cautery should not be treated, especially since bilateral choroid plexus cautery has the complication of intellectual disability leading to memory and emotional impairment. 5.
