脑膜瘤是有包膜的“脑外”肿瘤,手术切除为主要治疗方法;然而肿瘤与周围脑组织能否完全剥离是影响预后的重要因素。作者分析了1974～1988年间150例脑膜瘤连病例的手术结果,结合CT及血管造影预测肿瘤的可剥离性。女103例,男47例,年龄15～85岁,平均58岁;42例术前有严重的神经功能障碍;肿瘤位于大脑凸面的22％,窦旁和镰旁24％,颅底41％,后颅窝13％,直径小于3cm的占14％,3cm～6cm的占57％,大于6cm的占29％。全组病例术前均行CT及脑血 Meningiomas are enveloped “cerebral” tumors, and surgical resection is the main treatment; however, whether the tumor and the surrounding brain tissue can be completely exfoliated are important factors affecting prognosis. The authors analyzed the surgical results of 150 meningioma cases from 1974 to 1988, combined with CT and angiography to predict the tumor’s strippability. 103 females, 47 males, aged 15 to 85 years old, average 58 years old; 42 patients had severe neurological dysfunction before surgery; the tumor was located in the convex 22% of the brain, paranasal and parasellar 24%, skull base 41%, 13% of the posterior cranial fossa, 14% of the diameter less than 3cm, 57% of the 3cm to 6cm, 29% of the greater than 6cm. All groups of patients undergo preoperative CT and cerebral blood preoperatively
