    PurposeAnterior cervical spine operations (ACSO) are generally considered to be safe and effective, but the vertebral artery (VA) is at risk during the procedure. Because the consequences of VA injury can be catastrophic, properly managing a VA injury is very important. However, due to the rarity of these injuries, there is no agreed upon treatment strategy.MethodsStudies were identified for inclusion in the review via sensitive searches of electronic databases through 31 December 2011. All cases included in the review were qualitatively analyzed to explore the relationship between type of VA injury management and neurological complications.ResultsSeventeen articles describing 39 cases of VA injury during ACSO were included in this study. Seven patients (17.9 %) had neurological complications followed by VA insufficiency. Two patients (5.1 %) had root damage due to ligation. One case (2.6 %) resulted in intraoperative death due to fatal bleeding. Delayed vascular complications were identified in nine (45.0 %) of the 20 patients that underwent only tamponade or hemostatic agent during the operation. Four patients underwent intraoperative endovascular treatment, and three of these patients had a cerebral infarction. All three patients who underwent clipping also had neurological complications. The five patients treated by direct repair did not have any complications.ConclusionOur review suggests the management of VA injury should be considered in order listed: (1) performing tamponade with a hemostatic agent, (2) direct repair, (3) postoperative endovascular procedures to prevent delayed complications. If tamponade fails to achieve proper hemostasis, additional procedures as endovascular embolization, clipping and ligation should be considered but carry the risk of neurological complications. Because of the limitations of this review, further studies are recommended with larger sample sizes.
