Intracranial meningiomas. Analysis of 344 surgically treated cases.

ABSTRACT

The authors present 344 (230 females, 114 males) surgical cases of intracranial meningioma. A total of 370 interventions (344 primary procedures, 10 reexplorations for neurologic deterioration, 16 operations for recurrence) were made. Mean follow-up was 38 months. The overall evaluation revealed that 306 (88.95%) patients were completely normal or in a better condition than before operation. 18 (5.23%) were in a worse condition after operation and 20 (5.81%) died. Results suggested that complications and mortality were mostly related to localization and large volume; we also still have problems with aggressive and malignant meningiomas.
