This article provides an up-to-date literature review on the role of pathological changes in the extracranial, trunk segments of the vertebral arteries (VA) in the development of chronic and progressive vertebrobasilar insufficiency (VBI). Improving methodology of differentiated reconstructive interventions for VA stenosis based on specifically determined vascular territory with application of microsurgery instruments and minimally invasive technologies has made it possible to determine that all other conditions that could lead to the formation of VBI should be excluded in patients with this clinical picture during the planning of arterial reconstruction, and possible outflow pathways and reactivity of the arteries of the vertebrobasilar territory should be determined.

The use of endoscopic assistance in transcranial microsurgical operations has started relatively recently and is not currently used routinely in neurosurgery. With the development of neuroimaging and microsurgical techniques in neurosurgery, minimally invasive surgery is currently actively developing, which provides a reduction in the volume of access and trauma of the intervention. One of the minimally invasive approaches used in chiasmal-sellar surgery is the supraorbital keyhole-access. This work is devoted to the description of features of visualization of anatomical structures of the chiasmal-sellar region using endoscopic techniques through microsurgical supraorbital keyhole-access.
