Lateral Perspective of the Vertebral Artery

Description

Rendered from a lateral perspective of the male head and neck, the vertebral artery can be followed as it arises from the subclavian artery and ascends through the foramina transversaria of the upper cervical vertebrae, typically C6 to C1, before curving medially toward the foramen magnum. Anterior to this deeper vessel, the common carotid artery continues superiorly to bifurcate into the internal and external carotid arteries near the angle of the mandible. Superficial venous pathways are also indicated in blue, running parallel and anterolateral to the arterial tree, while the cervical spine provides the bony corridor for the vertebral artery’s protected vertical course. This side view is the one clinicians tend to picture when localizing posterior circulation problems. Vertebral artery dissection after cervical hyperextension or rotation can produce lateral medullary ischemia, and the relationship of the artery to the transverse processes helps explain why symptoms may be provoked by neck movement. It also maps cleanly onto procedural anatomy: the vertebral artery lies at risk during anterior approaches to the cervical spine and during instrumentation near the uncinate process and transverse foramen. A small structure. Big consequences. Use this artwork for teaching cervical vascular anatomy in gross anatomy, neuroanatomy, and head and neck modules, or for illustrating vertebrobasilar insufficiency, vertebral artery dissection, and cervical spine surgical risk in textbooks, review articles, and patient education materials. It also suits angiography or CTA reporting guides that need a clear anatomic reference for the V1 to V3 segments in relation to the cervical vertebrae.
