With the popularization of medical knowledge and the progress of science and technology, the incidence of intracranial tumors is also more and more, and the technical level of treatment is also improved continuously with it. There is almost no kind of tumor and any part of intracranial tumors that is absolutely inoperable, and from the point of view of the effect of the treatment, the ideal one can save the patient’s life, and the almost one can prolong the patient’s life. However, the success of surgery does not mean the fundamental cure of the disease, and various complications may occur after surgery, leading to deterioration of the condition and even loss of life. When the patient is still hospitalized, these problems will be relatively better, no matter doctors, nurses or family members will find out in time and get proper treatment, but if it is a complication after discharge, it needs extra attention from family members and some routine knowledge. One of the most common post-surgical complications is increased intracranial pressure, which is a dangerous condition that can be caused by a number of reasons, such as the formation of hydrocephalus during the surgery, the formation of intracranial abscess after the acute phase of intracranial infection after the surgery has been controlled and turned into a chronic one, or the formation of abscess secondary to the infection caused by chronic seepage of blood and fluid, etc. Sometimes it is a single cause, and sometimes it is the simultaneous existence of two or more causes, which can all lead to an increase in the intracranial pressure. These can lead to an increase in intracranial pressure, and the patient may exhibit nausea, headache, vomiting when the headache is severe, and blurred vision in some cases, making it difficult to see clearly. When these feelings and discomfort occur, the first thing to think of, after the operation of the intracranial must have problems, immediately consult your surgery-related doctors by phone, the conditions are convenient to the hospital to do a checkup, more convenient and safe is to do a nuclear magnetic examination, so as not to miss the diagnosis. After the hospital examination, you will be more relieved. Of course, nausea, vomiting, headache and other manifestations described above after the surgery are not necessarily intracranial problems, but there are other conditions that can lead to them, such as colds, etc. However, the first reminder is to pay attention to the complications after the surgery because it cannot be delayed, and you will lose your life due to brain herniation in a longer period of time.
