Abstract
STUDY DESIGN: Case report and review of the literature. OBJECTIVE: To prevent and manage a suspected iatrogenic vertebral artery injury during a cervical spine anterior approach. SUMMARY OF BACKGROUND DATA: The anterior spine approach is a common surgery with few complications. One of the rare but significant risks is vertebral artery injury. Consequences of vertebral artery injuries are often delayed. Therefore, it is essential to prevent this complication and to know how when exploring after a suspected vertebral artery injury. METHODS: Report of a case and review of the literature. A 61-year-old woman presented with a cervical schwannoma involving the C5-C6 foramen. She had undergone surgery 22 years before by the posterior approach. We performed an anterior cervical approach. After 12 days, a vertebral artery pseudo-aneurysm occurred. Our review of the literature is focalized on vertebral artery injuries during cervical surgery by the anterior approach. RESULTS: The patient was treated by coil embolization with a good outcome. To our knowledge, only 6 cases of vertebral artery pseudo-aneurysm after surgery have been reported in the literature. CONCLUSION: According to the literature, vertebral artery pseudo-aneurysms resulting in anterior cervical approach are rare but their consequences could be severe. Prevention begins by detailed surgical planning. Peroperative imaging is helpful. Any suspected vertebral artery injury should postpone a contralateral approach before angiographic imaging.
