第III脑室处于脑部解剖的中心位置,周围有丘脑、下丘脑、大脑深部静脉等重要结构。在这一区域手术操作,要求避免对周围血管、神经结构任何细微的损害。在保护解剖功能的同时,还要获得尽可能大的操作空间,这使此类手术成了神经外科具有较高难度的手术。我科经治1例第III脑室星型 The third ventricle in the brain anatomical center, surrounded by the thalamus, hypothalamus, deep brain veins and other important structures. Surgical procedures in this area require the avoidance of any subtle damage to the surrounding blood vessels and nerve structures. While maintaining the anatomical function, but also to obtain as much space as possible, which makes such surgery has become a neurosurgery surgery more difficult.
