[An anatomical study on the applicability of direct endoscopic exclusion of the ethmoid arteries for devascularization of the anterior skull base structures].

Unlabelled: The anterior skull base structures are the site of initial growth of histologically different tumors. The difficulties in their removal are often associated with significant vascularization, which may limit the amount of resection due to abundant intraoperative blood loss. Midline tumors are primarily fed by the ethmoid arteries that are not accessible to embolization.

[A technique of manufacturing anatomical preparations of the human brain based on injecting vessels with colored silicone (a technical note)].

Objective: The objective was to produce anatomical preparations by injecting vessels with colored silicone to study the brain and skull base anatomy.

Material And Methods: Fresh, undissected, and unfixed cadavers were used. The internal carotid arteries and internal jugular veins were identified on both sides of the neck.
