Spinal meningioma and factors predictive of post-operative deterioration.

Spinal meningiomas are usually benign tumors whose treatment is based on complete surgical resection. Progress in surgical techniques has resulted in lower morbidity rates and improvement in post-operative recovery. In this study, we observed several factors associated with clinical deterioration. Before surgery, patients should be fully informed of these predictive factors of post-operative deterioration and their association with surgical morbidity.
