无论是经纵裂-终板入路切除某些Ⅲ脑室内颅咽管瘤,还是经纵裂入路行前交通动脉动脉瘤手术,都必须充分了解前交通动脉及其穿通支的显微解剖。 本文报告25例福尔马林良好固定脑标本的前交通动脉及其穿通支的显微解剖观察结果。 前交通动脉 全部均存在,长1.5～8.8mm,平均4mm,直径0.2～2.5mm,平均1.7mm。典型单根前交通动脉10例(40％),余60％均存在不同形式的变异。其中丛状前交通动脉9例(36％),前交通
Whether through the longitudinal split - end-plate approach for the removal of some Ⅲ intracranial craniopharyngioma, or by the longitudinal splitting of the line of access artery aneurysm surgery, we must fully understand the anterior communicating artery and its penetrating branch of the micro-anatomy . This article reports microscopic anatomical observations of the anterior communicating artery and its penetrating branches in 25 formalin-fixed brain specimens. Anterior traffic artery all exist, long 1.5 ~ 8.8mm, an average of 4mm, diameter 0.2 ~ 2.5mm, an average of 1.7mm. Typical single anterior communicating artery in 10 cases (40%), more than 60% there are different forms of variation. Among them, 9 cases of plexiform anterior communicating artery (36%), the former traffic
