Anterolateral Approach to Subaxial Segment of the Cervical Vertebral Artery



The vertebral artery (VA) is classically divided into V1, V2, V3, and V4 segments. With consideration of the unique anatomy of the vertebral artery, the exposure of different cervical spine pathologies in close proximity of this artery, at each segment, has remained a risky and a challenging issue in spite of progress in surgery. Vertebral artery V2 segment exposure, control and transposition via anterolateral approach may be advised as a part of total spondylectomy for a vertebral tumor. It may also be considered for tumors located in the foramen with extension to the anterior aspect of the neck, such as giant dumbbell schwannomas. Obviously, for this purpose, a thorough knowledge of the surgeon about the anatomy of the vertebral artery in the subaxial cervical spine is necessary.

Herein, the steps of V2 segment exposure with description of the tips and the tricks of the procedure will be described in two illustrative cases.
