[Surgery of acoustic neurinoma in a hemodialyzed patient].
Successful surgical treatment of acoustic neurinoma in a case of hemodialyzed patient is reported. A 42-year-old female patient, who had been treated by hemodialysis, was diagnosed as having a C-P angle tumor by CT scan. She was refered to our clinic on June 24, 1983. Laboratory examinations on admission showed severe anemia and renal dysfunction. Every possible treatment was done in order to improve the laboratory data preoperatively. Another big problem in this case of hemodialyzed patient was brain edema and bleeding tendency. In order to cope with brain edema, intravenous administration of glycerol and slow hemodialysis for three days were performed preoperatively. These treatments were thought to be effective to reduce bleeding tendency also. During operation, however, heavy swelling of the cerebellum forced us to resect one third of the hemisphere to remove the tumor totally. In addition to this, postoperative mild bleeding in the cavity after tumor resection, subcortical hemorrhage around the shunt tube and oozing from the wound were observed. The patient was discharged from the hospital four months after surgery without any neurological deficit. The way of recovery, however, was not uneventful, because the patient developed various kinds of postoperative complications as mentioned above. In the postoperative managements, we felt almost as if we were treading on thin ice. Neurosurgical management in hemodialyzed patients is not yet very common. We should improve the postoperative management by adding new experience with similar cases.
