桥小脑角肿瘤因为位置深在,周围解剖结构复杂,一直被视为神经外科手术的难点。岩静脉常常与该区域肿瘤上极关系密切。尽管在术中牺牲岩静脉对大部分患者无明显影响,但影响一旦出现,往往严重影响患者预后。本研究通过回顾近期临床资料及文献,总结该区域肿瘤术中岩静脉的保护方法及意义。 Because of the deep location of the cerebellopontine angle tumor, the surrounding anatomical structure is complex and has long been regarded as a neurosurgical difficulty. Rock veins are often very closely related to the tumors in this area. Although the sacrificial petrosal vein during operation has no significant effect on most patients, once the impact appears, it often has a serious impact on the prognosis of patients. This study reviewed recent clinical data and literature to summarize the methods and significance of the protection of petrous veins in oncological tumors in this area.
