Patient: Description of condition (onset, main symptoms, hospital visited, etc.): Female, 1 year and 2 months old, head circumference 54 cm, non-verbal. There are no other obvious symptoms. The MRI examination done at the local hospital indicates bilateral lateral brain and third ventricle dilatation, which is consistent with obstructive hydrocephalus. I would like to ask what is the situation and how should I treat it? Is surgery necessary? What is the approximate cost of surgery? What is the risk of surgery? Beijing Tiantan Hospital Neurosurgery Department: Like a midbrain conduit obstruction, surgery is needed, the risk is not big, the cost is about 30,000. The patient: Dr. Yuan, then December 3 directly to your hospital, I want you to see the child, I do not know what number you sit, can have time? If the surgery is done, how long will the hospital stay be? Beijing Tiantan Hospital Neurosurgery Department: I’m on holiday on New Year’s Day and will start working on the 4th. The bypass surgery usually requires about ten days of hospitalization. Patient: I’m in a bit of a hurry. Your hospital said there are no beds available, can you get a bed after the 4th? Can you do the surgery without a bed? The hospital’s collaborating hospital in Beijing (the General Hospital of the Armed Police) is a good place for you to stay if you wish. Patient: Dr. Yuan, I would also like to ask if there are any complications after the surgery and how is the healing process of the child? Will he be able to heal like a normal child? Do you need any more treatment in the future? Thank you! Neurosurgery Department of Beijing Tiantan Hospital? The patient’s condition may not be the same as that of a normal child.
