Meningiomas in elderly patients. Clinico-therapeutic considerations

This study examines the immediate and long-term results of surgical treatment for intracranial meningioma in patients aged 65 and over. Average patient age was 69 years. The most frequent localizations were the convexity (29.8%) and the sphenoid wing (20.1%). Preoperative risk factors included hypertension (16.1%), cardiopathies (16.1%), diabetes (12.9%) pneumopathies (12.9%) and peripheral vascular diseases (9.6%). All patients were assessed according to the Karnofsky Performance Status (KPS). Operative mortality was 18.5% (23 cases). At long term follow up (minimum 4 months, maximum 12 years, average 5 years) 31.5% of patients were cured, 32.3% had improved and 4% had worsened. The risk factors that mainly influenced results included poor preoperative clinical condition as expressed by low KPS, while the most frequent medical postoperative complications that increased the rate of operative mortality were brain edema, infections and lung embolism. © 1993 Masson Italia Editori.
