[The excessive cerebrospinal fluid drainage syndrome as a complication of the surgical treatment of hydrocephalus].

The paper presents a clinical case of severe excess cerebrospinal spinal fluid drain syndrome with hematomas of the cerebral hemispheres being formed in a 18-year-old young man undergone ventriculoatriostomy with mean-pressure pump implantation. A complication occurred 6 months after surgery and ran progressively. Closed external drainage of hematomas greatly reduced their volumes, but deteriorated the patient's condition due to the development of excess drain syndrome. Replacement of the mean-pressure pump by a high-pressure one rapidly normalized the patient's status.
