摘要
目的观察第四脑室的显微外科手术治疗效果。方法 35例第四脑室肿瘤中,室管膜瘤15例,髓母细胞瘤12例,血管网状细胞瘤4例,星形细胞瘤4例,除4例先行经右枕角穿刺脑室外流后开颅外,其余采用枕下后正中入路开颅,于显微镜下分块或完整切除肿瘤。结果肿瘤全切除23例,次全切除8例,大部分切除4例。术后发生并发症4例,其中脑神经功能障碍1例,术后硬膜外血肿1例,小脑缄默征1例,意识障碍后死亡1例。结论了解第四脑室肿瘤毗邻脑干及重要的神经结构,熟悉第四脑室的显微解剖,术中保护脑干功能,是显微镜下手术切除肿瘤的关键。
Objective To evaluate the efficacy of microsurgery for 35 cases of the fourth ventricle tumors. Methods 35 cases of the fourth ventricle tumors underdong microsurgery were reviewed and followed up. 31 cases were treated via suboccipital midline approach,while 4 via right anterior horn approach.Results Total resection was achieved in 23 cases,and subtotal resection in 12 cases. Conclusion Because the fourth ventricle adjoins brainstem and key nerve structures,familiarity with anatomical structure of the fourth ventricle and the protection of brainstem function during surgery are keys to remove the fourth ventricle tumors effectively and safely under microscope.
