Ventricular compression displacement is a CT examination or cerebral angiography finding of ventricular displacement and ventricular compression, mostly in traumatic brain injury or brain tumors. The causes of ventricular compression and displacement are usually cerebral hematoma, cerebral edema, cerebral hypertension or tumor compression, which leads to ventricular compression and displacement of ventricles or midline structures in different directions. If you have brain tumor, you should pay attention to the following kinds of care: 1. Pay attention to the adjustment of body position, when there is no shock, you can elevate the head of the bed 150-300, do not make the neck twisted or the chest pressed, in order to facilitate intracranial venous reflux. 2. 2.Keep the respiratory tract unobstructed, remove the secretions in the respiratory tract in time, give oxygen regularly, and use hyperbaric oxygen chamber to give oxygen 2-3 times a day for 45 minutes each time when available. 3.Try to avoid coughing, sneezing, dry vomiting, timely treatment of constipation, keep the stool unobstructed. 4.Limit water intake. For patients with brain tumor with symptoms of increased intracranial pressure and cerebral edema, the body should be supplied with the minimum amount of fluid and blood electrolytes should be checked frequently to prevent water and sodium retention from aggravating cerebral edema. In addition, we should try to reduce the occurrence of traumatic brain injury, avoid exposure to radiation, do a good job of head protection, avoid various infections, and cell phone radiation, although there is no evidence that cell phone radiation is directly related to brain tumor, there is also no evidence that there is no relationship between the two. The best way to prevent brain tumor is to avoid long time cell phone chat and prevent cell phone radiation.
