Obstructive hydrocephalus and non-obstructive hydrocephalus are two common clinical types of hydrocephalus. Obstructive hydrocephalus is mainly caused by stenosis or atresia of the central aqueduct, hypoplasia of the interventricular foramen, congenital developmental malformation, and compression of the aqueduct by brain tumors. The clinical manifestations of infants with obstructive hydrocephalus are generally increased head circumference, difficulty in sucking and feeding, visual and intellectual developmental impairment, and even drowsy convulsions. In adults with obstructive hydrocephalus, headache, vomiting, blurred vision, dizziness, seizures, and in severe cases, increased intracranial pressure may occur. Is obstructive hydrocephalus serious and can it recover on its own? The severity of obstructive hydrocephalus depends on the amount of fluid that has accumulated. If the obstruction is mild, some of it is still open, but the absorption of cerebrospinal fluid is slow. In this case, it is recommended to combine the patient’s clinical symptoms and medical history with imaging to make a comprehensive judgment. If the fluid accumulation is large and the channel is completely blocked, then within a short period of time the patient may appear coma, bilateral pupil dilatation, or even respiratory and cardiac arrest, or even life-threatening, which is more serious and impossible to recover by itself, the only solution is to take targeted treatment measures. If the condition is not serious in the initial stage, it can be treated by conservative treatment methods, but in severe cases, it can be treated by cerebrospinal fluid shunt surgery, which is performed by directing cerebrospinal fluid from the ventricles to other parts of the patient’s body to reduce fluid accumulation in the brain, thus restoring the balance between secretion and absorption of cerebrospinal fluid. This procedure is a common treatment in neurology, but it is easy to operate, but postoperative problems such as infection and blockage can easily occur. The specialist technique for cerebrospinal fluid is the ideal technique for treating hydrocephalus, as it breaks the limitations of traditional shunts and effectively avoids complications. The advantage of this specialized technique is that it can effectively treat any type of hydrocephalus with very good results.
