Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...

  • 为了将解剖学测量与潜在的内镜损伤相关联.

主要方法:

  • 对45名接受灵活神经内镜 (3.9毫米直径范围) 的患者的分析.
  • 根据病理学 (例如,水头,正常解剖学) 划分患者的分类.
  • 应用一个几何图表来测量adytum变形和记录流行性损伤.

主要成果:

  • 从正常状态到水头状状态,观察到后部指针和水道通道接入区域之间的比率下降,以及顶点角的增加.
  • 与这些几何测量相关的垂体损伤.

结论:

  • 大脑水管可扩展到大约4毫米,这是灵活的神经内镜直径的安全极限.
  • 阿迪图的三角形图形模型确定了三种模式,有助于在水道导航方面做出内部操作决策.
