Most hydrocephalus is caused by traumatic brain injury. To determine the severity of hydrocephalus, a CT scan is required to do so. But most patients are not sure how to look at the brain CT film hydrocephalus? In fact, ordinary patients do not need to care about how to look at the CT film, it can be left to the judgment of professional doctors. But since the question is asked, here is a brief description of it, in order to let the majority of patients for their own condition to understand, and then confirmed after the diagnosis to actively and effectively carry out treatment. There are many causes of hydrocephalus, such as head trauma, intracranial infections, intracranial tumors, or other less obvious pathological factors or even congenital factors. Usually, the diagnosis can be confirmed by CT examination. So, how to look at brain CT films of hydrocephalus? When looking at the brain CT film, you will find that if there is hydrocephalus, then the main manifestation is the enlargement of the ventricles. Once this happens, you should actively go to the hospital for the corresponding professional examination, and after the diagnosis is confirmed, actively carry out treatment under the guidance of the doctor. Avoid strenuous exercise, as well as smoking and drinking. To actively and effectively treat hydrocephalus, it is important to find an effective treatment method. Most hospitals currently use the traditional ventriculoperitoneal shunt procedure, which uses a shunt tube to divert excess cerebrospinal fluid from the ventricles of the brain to the abdominal cavity and other locations to be absorbed. This traditional shunt procedure is risky and can easily lead to complications after surgery, so many patients are concerned about the lack of good results after treatment with this surgical method. Although the treatment of hydrocephalus is difficult, there are still some doctors who are constantly working on it, and it is because of the efforts of these doctors that breakthroughs in treatment methods have been made again and again.
