侧脑室三角区肿瘤手术相关入路研究进展

Research progress on the related surgical approaches of the tumors at thetrigone of the lateral ventricle

目的：总结并归纳侧脑室三角区肿瘤手术相关入路的选择。方法在 PubMed、Springerlink、Sciencedirect、CNKI 等数据库中以“侧脑室三角区肿瘤”及“手术入路”为关键词，搜索1997年1月—2015年1月国内外有关侧脑室三角区肿瘤的研究进展，进行总结归纳。结果侧脑室三角区肿瘤的手术入路可以概括为直接入路和自然间隙入路，直接入路包括上顶枕叶皮质入路、经颞皮质入路、经顶颞入路及经枕入路等，自然间隙入路包括后纵裂经胼胝体入路、外侧裂远端入路、后纵裂经楔前叶入路、后纵裂对侧楔前叶入路及小脑上经小脑蒂侧副沟入路等，各种手术入路各有其优缺点及适应证。结论侧脑室三角区肿瘤多为良性肿瘤，手术是其最佳治疗手段。应根据肿瘤生长特点选择安全、有效、个体化的手术入路。

Objective To summarize the selection of the related surgical approaches of the tumors at the trigone of the lateral ventricle. Methods To review and summarize the recent research progress about the tumors at the trigone of the lateral ventricle in China and abroad from January 1997 to January 2015 by searching the PubMed,Springerlink,Sciencedirect, and CNKI databases using the key words ＂ the tumors at the trigone of the lateral ventricle＂ and ＂ surgical approaches＂ . Results The surgical approaches of the tumors at the trigone of the lateral ventricle can be summarized as the direct approaches and the natural gap approaches. The direct approaches include the superior parietal occipital transcortical, temporaltranscortical, transtemporalparietal, transoccipital approach. The natural gap approaches include posterior transcallosal, lateral transsylvian, posterior interhemispheric transfalx transprecuneus, posterior interhemispheric contralateral transprecuneus and supracerebellartranstentorial transcollateral sulcus approach. Each approach has its advantage, disadvantage and indication. Conclusions The tumors at the trigone of the lateral ventricle are usually benigh tumors and surgery is the optimal way to treat them. We should select safe, effective and individualized surgical approaches based on the growth characteristics of the tumors.
