Background And Purpose
Method
All patients who were preoperatively diagnosed (between 2010 and 2014) with giant meningiomas involving the SSS in Ward 10 at the Neurosurgery Department of Beijing Tiantan Hospital were enrolled in this study. Patient charts, imaging findings, and outcomes were examined.
Conclusion
The rigorous preservation of cortical veins, draining veins, and eloquent areas should be implemented during the resection of large tumors that obstruct the SSS. Suitable individualized approaches associated with full exposure and low cerebral perfusion pressure levels after surgery are critical for favorable results, and the reconstruction of the SSS may not be necessary.
Main results
The study included 6 male and 4 female patients with a mean age of 46.8 ± 10.7 years. The tumor sizes varied from 7 to 12 cm (mean, 8.8 ± 2.0 cm). All patients underwent customized craniotomies, and aggressive surgery for resection of the invaded SSS was performed. Simpson grade I removals were achieved in all cases. No cases of perioperative mortality occurred. Three patients required cranioplasty as a result of a decompressive craniectomy that was performed during the primary surgery. Histologic examinations showed 1 malignant and 9 benign meningiomas. During the follow-up period (mean, 29.0 ± 9.7 months), recurrence/progression occurred in 1 patient, and 1 patient was lost to follow-up. The recent Karnofsky Performance Score was 80 ± 32.3 and was improved in 5 patients and stabilized in 3 patients. In addition, 7 patients lived independently.
