Obstructive hydrocephalus is more common in neurosurgical clinics, where obstruction of the channels occurs due to hematomas, tumors, abscesses, and some congenital anomalies, allowing poor cerebrospinal fluid circulation. The symptoms of this hydrocephalus vary with different medical history and age. In infants and children with obstructive hydrocephalus, the clinical manifestations are usually an increase in head circumference, difficulty in sucking and feeding, visual and intellectual developmental impairment, and even drowsiness and convulsions. In adults with obstructive hydrocephalus, headache, vomiting, blurred vision, dizziness, seizures, and in severe cases, increased intracranial pressure may occur. Obstructive hydrocephalus generally has 3 features on CT: 1) round enlargement of the lateral part of the superior frontal horn; 2) enlargement of the temporal horn; and 3) periventricular hypodensity; CT helps to determine the site of obstruction by showing the enlarged part of the ventricular system versus the normal part on consecutive scans. Mild obstructive hydrocephalus may be partially obstructed in the early stage, and these patients can be further controlled by conservative treatment and then observed regularly, and surgical treatment can be performed when appropriate. In the case of severe obstructive hydrocephalus, which is serious and leads to brain herniation and death, patients should not take it lightly and carelessly, and should face its hazards and go to hospital for treatment as soon as possible. Can severe obstructive hydrocephalus be cured? According to the current medical conditions, most patients with hydrocephalus can gradually recover after scientific and effective treatment. Cerebrospinal fluid specialist technology is a more comprehensive and systematic approach, namely cerebrospinal fluid specialist technology. The successful use of this technology has greatly improved the clinical treatment of hydrocephalus, especially in the treatment of obstructive hydrocephalus, and many patients with obstructive hydrocephalus have recovered well after treatment with the cerebrospinal fluid specialist technology.
