Patient: First, he was hospitalized with pneumonia at the age of 1 month, and the doctor found some hardness in his hands and feet, and suspected brain problems. Laboratory tests: 1 month CT result was a blood clot in the brain, three courses of hyperbaric oxygen, three courses of drip, and CT again, became mild hydrocephalus (obstructive). What I want to ask is how long will it take for him to absorb it slowly? Will the hydrocephalus increase? Is it harmful to his intelligence and development? What can I do as a mother? Will rehabilitation help him? Xiao Hua, Department of Pediatrics, Guangzhou Women and Infants Hospital: If the baby has been diagnosed with obstructive hydrocephalus, he must be followed up and observed and operated if necessary. Because cerebrospinal fluid is produced by the lateral ventricular choroid plexus and flows to the third ventricle via the interventricular foramen, together with the cerebrospinal fluid produced by the third ventricular choroid plexus, it flows into the fourth ventricle via the middle cerebral aqueduct, and then converges with the cerebrospinal fluid produced by the fourth ventricular choroid plexus to flow into the subarachnoid space via the median and lateral foramina of the fourth ventricle. Once the outflow channel is blocked, it is difficult to be absorbed. Consultation with cranial surgery is recommended. Patient: The baby has been diagnosed with mild obstructive hydrocephalus, the problem is that both the director of the brain department and the pediatrician said that it was fine and let him absorb it slowly on his own. The chief of the hospital said that my child also had gastrointestinal problems and some stiffness in his hands, and that he suspected brain problems and suggested a CT scan, which showed a blood clot in his brain. We followed the director’s advice and did three courses of hyperbaric oxygen, three courses of drops, and a CT scan, and the result was mild obstructive hydrocephalus. My son seems to be very energetic on the surface, his eyes are bright, he loves to smile, he can roll over at almost 5 months, he loves to watch TV, he will turn his head to look at the sound, but he has poor resistance, he is easy to catch a cold, he still has some muscle tone in his hands, but not in his feet. What I want to ask is whether he can get better on his own? Experts say that 60% will get better on their own, but who knows how long it will take? If he doesn’t get better, will it affect his physical and mental development? His resistance is so weak that he can easily get pneumonia when he gets a cold. What can we do for him? Xiao Hua, Department of Pediatrics, Guangzhou Women and Infants Hospital: Mild obstructive hydrocephalus can continue to be followed up and observed, while poor resistance can be checked by the hospital for immune function and, if necessary, immune-enhancing drugs can be taken. Patient: My son has mild obstructive hydrocephalus, and he has been having fever for the past few days, and it is very difficult to go down. What should we do? What is the medicine to enhance immune function? Zinc supplements? How do we know if his hydrocephalus is healed? Does the absence of muscle tone in his arms and legs mean he is well? If his hydrocephalus is not healed, is it difficult to treat him? Xiao Hua of the Department of Pediatrics at Guangzhou Women and Infants Hospital: Fever that does not subside should first be considered an infection that is not under control, and secondly, hydrocephalus can also affect thermoregulatory functions. If you want to know the current hydrocephalus situation and immune function, you’d better go to the local hospital, because the results of family observation and the doctor’s examination are sometimes not exactly the same. Patient: What I want to ask is: If mild obstructive hydrocephalus remains like this for the rest of his life – no absorption, no change – will it have an impact on his body and intellectual development? Xiao Hua, Department of Pediatrics, Guangzhou Women and Infants Hospital: As long as the obstruction is not lifted, hydrocephalus will always exist, and the impact on physical and intellectual development will vary from person to person, in addition to the degree of hydrocephalus. Patient: How can the obstruction be relieved? Do you rely on drops? There are some Chinese medicine books that treat hydrocephalus, but the ones in them are more serious, but my son doesn’t even see any problems with his mind, his eyes are bright and he loves to smile. Guangzhou Women and Infants Hospital Pediatrics Xiao Hua: Obstructive hydrocephalus, severe cases must be operated, mild cases can continue to be observed.
