作者报告27例天幕脑膜瘤手术治疗的体会。病者最常见的临床表现为颅内压升高、颅神经、锥体束和小脑的损害。动脉造影对确定肿瘤与动、静脉和静脉窦的关系很重要。该组累及静脉窦者13例。每例都有椎动脉系统移位,但大脑后动脉和小脑上动脉特征性的分离仅2例。该组除早期(使用CT前)2例天幕侧翼脑膜瘤经枕下中线探查作肿瘤次全切除后,因脑肿胀和脑干梗塞而死亡外,其余全部随访(平均5.5年)。其中良(恢复到病前活动水平)19例,好5例,差1例。肿瘤全部切除的14例,
The authors report on the experience of 27 cases of surgical treatment of thawed meningiomas. The most common clinical manifestations of patients are increased intracranial pressure, cranial nerves, pyramidal tract, and cerebellar lesions. Arterial angiography is important for determining the relationship between tumors and arterial and venous sinuses. This group involved 13 cases of venous sinus. Each case had a vertebral arterial system shift, but the characteristic separation of the posterior cerebral artery and superior cerebellar artery was only 2 cases. This group was followed up (average 5.5 years) except early (using CT) 2 cases of tympanic meningioma after subtotal neoplasmectomy through the suboccipital midline exploration and brain death due to brain swelling and brain stem infarction. Among them, 19 cases were good (recovered to pre-operative activity level), 5 cases were good, and 1 case was poor. 14 cases of total tumor resection,
