Vertebral Artery Location in Relation to the Vertebral Body As Determined by Two-Dimensional Computed Tomography Evaluation

Abstract

According to our measurements, the risk of vertebral artery laceration is greater at more cephalad vertebrae during lateral extension of central decompressive procedures and lateral nerve root decompression. Because of the variability of these parameters between individuals, accurate individual preoperative localization of the vertebral arteries is recommended.
