Hydrocephalus is a condition that is usually caused by an increasing amount of intracranial cerebrospinal fluid, causing abnormal enlargement of the ventricles and or subarachnoid space, thus causing a series of symptoms in the clinical setting, which seriously affects the patient’s health, normal life, study and work. Hydrocephalus drainage is a secondary neurosurgical procedure with high safety Most neurosurgeons believe that once hydrocephalus is present, most patients require surgical treatment. Usually, after hydrocephalus drainage, most patients will need a shunt later in life. This procedure is usually a lateral ventricular drainage and is used to relieve symptoms in the acute phase. Although many people also actively seek medical treatment in the early stage, they are particularly fearful inside when they hear about the surgery due to the lack of medical knowledge. Here we would like to introduce to you that hydrocephalus drainage surgery is a secondary neurosurgical procedure, a minimally invasive surgery, usually performed under local anesthesia, with a high degree of safety, so patients and their families should not be too worried and nervous, but should be in a good frame of mind and receive surgery as soon as possible to avoid delaying the disease and causing more adverse consequences. Hydrocephalus symptoms are complex and diverse, and timely treatment is important According to the survey, hydrocephalus without timely treatment can cause limb walking impairment, cognitive decline, urinary and fecal incontinence, reduced intelligence and other hazards. In addition, almost everyone has the possibility of the disease, and there are many newborns who have hydrocephalus for various reasons in clinical practice. The symptoms of hydrocephalus in infants are complex and varied, and are often overlooked by parents because of the young age of the child, who cannot express himself verbally. Therefore, parents must pay close attention to the child’s every move after birth. If the child’s fontanelle is not closed, you can find full fontanelle, enlarged fontanelle or not closed, larger head than the same age, sunset sign, etc. Never report a lucky thought that your child’s big head is smarter than others. Experts remind that big-headed dolls are not necessarily smart, when children appear to cry for no reason, vomit and refuse to eat when eating, usually there are twitching and other abnormal behavior, it is likely to have hydrocephalus. In adults, hydrocephalus is characterized by intermittent headache, head swelling, head sinking, dizziness, tinnitus, ear blockage, vision loss, limb weakness, etc. Chronic hydrocephalus is characterized by chronic intracranial pressure increase, bilateral temporal or whole cranial pain, nausea, vomiting, optic nerve papillary edema or optic nerve atrophy, intellectual developmental disorders, motor dysfunction, etc. Normal pressure hydrocephalus can be characterized by limb disorders, intellectual disorders The three main signs of normal pressure hydrocephalus are physical impairment, intellectual impairment, urinary and stool disorders. With the rapid progress of medicine, modern neurosurgery, whether preoperative diagnosis, or surgical skills have been unprecedented development, so do not avoid illness, go to the regular hospital as soon as possible to take effective treatment measures, in order to recover as soon as possible.
