    Abstract:
    BACKGROUND: Since the introduction of CT and then MRI in the clinical practice, the number of elderly patients with intracranial meningiomas observed in neurosurgical departments has increased to three/four times. Considering that some patients die because of their meningioma and others die with their meningioma, the neurosurgeon should not only be able to eradicate surgically the lesion, but also to decide if that benign tumor should be treated or not. MATERIALS AND METHODS: Forty-three patients with intracranial meningioma, aged over 65 were operated upon between 1989 and 1995. They constitute about one fourth of all the meningioma-patients operated upon in that period at our Department. Main symptoms were focal deficits, psychorganic syndrome, and seizures. Mean duration of symptoms was 15 months, with 30% of the histories lasting less than 3 months. Associate pathologies were those typical of the elderly population with hypertension and senile cardiopathy at the first places. Two patients had insulin-dependent diabetes, 2 prostatic carcinoma, and 8 were obese. MRI was useful either in depicting the location of the tumor or in helping the surgeon to give a correct operative indication and risk evaluation. MRI criteria for risk evaluation were severe edema and venous vascular infiltration. Forty-five operations were performed. Their duration was not a risk factor by itself, it only reflected the difficulty of the removal, due to the location of the tumor. Dissection of tumor remnants from main arteries or veins was never attempted in this group of patients; total removal was achieved in 75.5% of the cases. RESULTS: Immediate postoperative results were good in 71% of cases. Four patients died (9%). Long term results were evaluated in 29 patients (mean follow-up period: 35 months). Twenty-two patients (76%) had excellent or good results, 5 (17%) fair, and 2 (7%) had severe neurological dysfunctions and needed continuous assistance. CONCLUSIONS: Surgical risk factors typical of this age group were identified: cranio-spinal location, damage to the cortical or deep venous system, severe peritumoral edema, and poor neurological preoperative conditions. Systemic risk factors were insulin-dependent diabetes and obesity.
