自从 Dandy 采用右侧额叶切除经室间孔入路显露三脑室肿瘤以来,还有人采用过其他各种手术入路,如 Poppen 右额叶切开经室间孔入路;VanWagnn 枕叶切开经侧脑室入路;Dandy 经胼胝体松果体肿瘤切除;Jamieson 枕下经天幕入路;Stein 幕下小脑上入路等。不论采取何种入路,为了避免术后产生严重的并发症,都不能损伤脑实质特别是三脑室周围的重要组织和大脑血管。切除三脑室肿瘤,对三脑室壁的某些损伤虽不可避免,因此应注意终 Since Dandy used the right frontal lobe resection to expose the third ventricle tumor via the interventricular approach, other approaches have been used, such as the Poppen right frontal incision through the interventricular approach; VanWagnn occipital incision Lateral ventricle approach; Dandy resection of pineal tumors in the corpus callosum; Jamieson under the pillow through the nave approach; Stein under the submental cerebellar approach. Irrespective of the approach taken, important tissues and cerebral blood vessels around the brain parenchyma, especially around the third ventricle, cannot be damaged in order to avoid serious complications after surgery. Resection of three ventricle tumors, although some damage to the wall of the third ventricle is inevitable, so should pay attention to the end
