三脑室区肿瘤的手术入路根据病变部位有适用于前部病变的经额叶皮质入路、经胼胝体前部入路、经终板入路,主要适用于中部病变的脉络丛下入路、经脉络裂入路和脉络裂下经中央帆入路,主要适用于后部病变的枕部经小脑幕入路、幕下小脑上入路、经胼胝体后部入路及经侧脑室三角区入路。解剖和临床研究表明经胼胝体-穹隆间入路到达三脑室最近、术后并发症少。掌握该入路路径中扣带回、胼周动脉、胼胝体、穹隆、前连合等重要神经结构的显微解剖学知识,有利于术前手术计划的制定和实施手术。 Three ventricle tumor surgical approach according to the lesion has a frontal cortex for the frontal cortex approach through the corpus callosum anterior approach, the endplate approach, mainly for the central pathological choroid plexus approach, The meridians and the rupture of the cleft path through the central sail into the road, mainly for the posterior lesion of the occipital transmissing through the tentorium, supratentorial cerebellar approach, after the corpus callosum posterior approach and by the lateral ventricle triangle approach . Anatomical and clinical studies have shown that the corpus callosum - inter-dome approach to the third ventricle nearest, postoperative complications less. To grasp the microanatomy knowledge of important nerve structures such as cingulate gyrus, periaphral artery, corpus callosum, vault, anterior commissure and so on in this path is conducive to the preoperative planning and implementation of surgery.
