Posterior third ventricular lesions often cause obstructive hydrocephalus. Thus, a combined endoscopic third ventriculostomy (ETV) and endoscopy biopsy are often the first treatment. However, the trajectories for both procedures can differ significantly, necessitating 2 entry points or a combined rigid-flexible technique.
We describe the use of a large cavum septum pellucidum as a route for performing the biopsy.
Using a rigid endoscope and a single trajectory, we were able to perform a transforaminal ETV and a transseptal, transcaval, interforniceal biopsy of the tumor.
Although described as a route to reach the anterior third ventricle endoscopically, we describe the use of the transseptal, transcaval, interforniceal approach to reach the posterior part of the third ventricle.
第三脑室后部病变常导致梗阻性脑积水。因此，内镜下第三脑室造瘘术（ETV）联合内镜活检通常是首选治疗方法。然而，这两种手术的路径可能有显著差异，需要两个入路点或采用软硬结合技术。
我们描述了利用大透明隔腔作为活检路径。
使用硬式内镜和单一入路，我们能够经室间孔进行ETV，并经隔、经透明隔腔、经穹窿间对肿瘤进行活检。
虽然经透明隔、经透明隔腔、经穹窿间入路被描述为内镜下到达第三脑室前部的路径，但我们在此描述该入路用于到达第三脑室后部。
