Hydrocephalus is a pathological result of a variety of causes that cause the amount of cerebrospinal fluid in the human skull to exceed the normal range, with an incidence of 0.3% to 0.5%. Hydrocephalus is mainly divided into obstructive hydrocephalus, traffic hydrocephalus and external hydrocephalus, and the treatment of different types of hydrocephalus is also different. Traffic hydrocephalus 1. Definition: The amount of intracranial cerebrospinal fluid exceeds the normal range due to obstruction of the extraventricular cerebrospinal fluid circulation pathway or absorption disorder, which may also be caused by excessive intracranial cerebrospinal fluid production. 2.Symptoms: symptoms of increased intracranial pressure, abnormal increase in head circumference, enlarged fontanelle, sunset eye sign and other hydrocephalus symptoms. 3.Diagnosis: Combining medical history, symptoms and signs is limited to the initial diagnosis, and the diagnosis is confirmed by auxiliary examination. 4.Treatment concept: Very few patients can heal themselves, and most of them need treatment; very few patients can be cured by conservative treatment, and most of them need surgery. 5.Treatment mode: clinically, cerebrospinal fluid shunt surgery is needed to establish cerebrospinal fluid circulation pathway and release the accumulation of cerebrospinal fluid. Obstructive hydrocephalus 1. Definition: A pathological phenomenon caused by congenital or acquired factors that obstruct the cerebrospinal fluid circulation pathway above the fourth ventricle, so that the cerebrospinal fluid flow into the subarachnoid space (or cerebellar medullary pool) is impaired. 2.Symptoms: symptoms of increased intracranial pressure, abnormal increase in head circumference, enlarged fontanelle, sunset eye sign and other hydrocephalus symptoms. 3.Diagnosis: Combine with medical history, symptoms and signs only for the first diagnosis, and confirm the diagnosis through auxiliary examination. 4.Treatment concept: Very few patients can heal themselves, and most of them need treatment; very few patients can be cured by conservative treatment, and most of them need surgery. 5.Treatment mode: Surgery to establish cerebrospinal fluid circulation pathway and release the accumulation of cerebrospinal fluid, earlier mostly with shunt surgery, but with the application of neuroendoscopic technology, triple ventriculostomy surgery has become a better choice. External hydrocephalus 1. Definition: Increased fluid accumulation in the subarachnoid space within the skull, i.e., excessive accumulation of water in a cavity between the skull and brain tissue. 2.Symptoms: crying, excitement, agitation, shrieking, jumping, restless sleep, waking up easily, difficulty in falling asleep, short duration of sleep, feeding difficulties, poor sucking, spitting up easily, enlarged head circumference. 3.Diagnosis: Combine with medical history, symptoms and signs for initial diagnosis only, and confirm the diagnosis through auxiliary examination. 4.Treatment concept: physiological external hydrocephalus can be left untreated; pathological external hydrocephalus needs to be treated according to the amount of fluid accumulation. 5.Treatment mode: shunt and external drainage can make the effusion absent in a short period of time; temporal muscle absorption is a long-term process of absorbing the effusion. In conclusion, although there is no obvious difference in symptoms between different types of hydrocephalus, there are major differences in treatment, but they can all be treated by shunting the collected cerebrospinal fluid through cerebrospinal fluid shunt surgery. Tips: No matter what type of hydrocephalus, the most important thing is to recognize the symptoms and go to the hospital in a timely manner. Once diagnosed, you should cooperate with your doctor for treatment as soon as possible to avoid other effects caused by hydrocephalus.
