“…There is only one description of this type of anatomical variation in the literature. [ 21 ] The endoscopic characteristics are particular and of great importance for the performance of fenestration. In our series, 12 patients (6.4%) had this variation and 10 (83%) had chronic hydrocephalus, so it can be said that the pathophysiology of the presence of this variation is related to the increased pressure on the 3VF that produces changes in transparency and neural lining.…”

“…The prepontine interval has been described as an important consideration at the time of surgery. [ 20 , 21 ] In the authors’ experience, a meticulous preoperative evaluation of the images is considered to relate to the anatomy of the basilar artery and avoid accidents at the time of communication, as well as performing the fenestration in the most rostral part of the tuber cinereum and posterior to the dorsum sellae. [ 20 ] The relationship between this variant and hydrocephalus is not clear, and in our series, the percentage of presentation is low [ Figure 3E ].…”

Background: Endoscopic third ventriculostomy (ETV) is currently used as a treatment for different types of hydrocephalus. However, the anatomical endoscopic variants of the third ventricle floor (3VF), as well as their surgical implications, have been underrated. The anatomic variations of the 3VF can influence the technique and the success rate of the ETV. The purpose of this article is to describe the anatomical variations of 3VF, assess their incidence, and discuss the implications for ETV. Methods: Intraoperative videos of 216 patients who underwent ETV between January 2012 and February 2020 at Hospital Infantil Universitario de San José, Bogotá, Colombia were reviewed. One hundred and eighty patients who met the criteria to demonstrate the type of 3VF were selected. Results: 3VF types were classified as follows: (1) Thinned, (2) thickened, (3) partially erased, (4) globular or herniated, and (5) narrowed. Conclusion: Knowledge of anatomical variations of the 3VF is paramount for ETV and it influences the success rate of the procedure.

The in vitro experiments show that under 4.0W the situation is considered safe, due to low penetration of heat, thus the chance of accidentally damaging critical structures like the basilar artery is very small. The clinical results show that the Thulium laser did not cause any bleeding of the basilar artery, and is a safe technique for laser endoscopic third ventriculostomy. Lasers Surg.
