Postoperative Stroke after Anterior Cervical Discectomy and Fusion in Patients with Carotid Artery Stenosis: A Statewide Database Analysis

Carotid artery injury and stroke secondary to prolonged retraction remains an extremely rare complication in anterior cervical discectomy and fusion (ACDF). However, multiple studies have demonstrated that carotid artery retraction during the surgical approach may alter the normal blood flow, leading to a significant reduction in the cross-sectional area of the vessel. Others have suggested that dislodgment of atherosclerotic plaques following manipulation of the carotid artery can be a potential risk for intracranial embolus and stroke.
