Health is very valuable, especially nowadays when various diseases are prevalent and health is in crisis. Hydrocephalus is one of the more common problems, and many people may not understand what hydrocephalus is. In fact, hydrocephalus is related to cerebrospinal fluid, and when suffering from certain cranial diseases or cranial trauma, it may lead to the obstruction of cerebrospinal fluid absorption and circulation in the brain, and then excessive secretion of cerebrospinal fluid will form hydrocephalus. Typical clinical symptoms of hydrocephalus include headache, nausea and vomiting, blurred vision, and in some cases, diplopia, vertigo and seizures. The dangers of hydrocephalus should not be underestimated, and it is crucial to actively take effective measures for treatment. In the treatment of hydrocephalus, medical experts generally agree that the prognosis for most cases is better with surgical treatment. The conventional surgical approach is hydrocephalus shunt surgery, which uses a shunt tube to divert excess cerebrospinal fluid within the brain to other parts of the body, such as the abdominal or thoracic cavity, where it can be absorbed. However, conventional shunt surgery can easily lead to complications, such as infection and blockage of the shunt, which can occur at a particularly high rate. How to deal with blocked hydrocephalus shunts? If the blockage is early postoperative and there is no recurrent fever, the blockage may be caused by postoperative bleeding and the shunt should be removed promptly; if the blockage is secondary to postoperative infection, the shunt should be removed, anti-infection treatment should be given, and cerebrospinal fluid purification should be done before shunt surgery.
