    BackgroundThe optimal stenting approach for traumatic pseudoaneurysms (PSA) of the extracranial internal carotid artery (ICA) remains underinvestigated. We present a case of a traumatic pseudoaneurysm of the extracranial ICA managed with stenting and review of prior published similar cases.MethodsThe systematic review followed PRISMA-S guidelines and included studies that investigated traumatic pseudoaneurysms of the extracranial ICA managed by stent placement. Statistical analysis assessed the association between the type of injury and stent type, dual antiplatelet therapy (DAPT) duration, and clinical presentation, and the association between stent type and DAPT duration.ResultsOur search yielded 82 publications with 135 patients with extracranial ICA PSA treated with stenting. The odds of neck hematoma presentation was 12.2 times greater for patients with penetrating rather than blunt injuries (P = 0.000002). Covered stents had 2.02 times higher odds of use for penetrating rather than blunt injuries compared to bare metal stents. (P = 0.0029). Shorter duration DAPT was seen with bare metal stents having 1.25 higher odds of DAPT duration less than one month compared to covered (P = 0.001).ConclusionsIn traumatic extracranial ICA pseudoaneurysms, covered stents are used more commonly for penetrating injuries compared to blunt injuries. Penetrating injuries are more strongly associated with the presentation of a hematoma compared to blunt injuries. Stent type may influence the recommended DAPT duration. Surgeons should consider these findings when selecting stent type and DAPT duration with patients presenting with traumatic extracranial ICA pseudoaneurysm.Copyright © 2024 Elsevier Inc.
