Endovascular Repair of Traumatic Aortic Injury Using a Custom Fenestrated Endograft to Preserve the Left Subclavian Artery

Abstract

Purpose: To describe the use of custom fenestrated endografts to preserve left subclavian artery (SCA) flow when requiring coverage during endovascular repair of blunt aortic injury (BAI). Case Report: A 39-year-old male involved in a motor vehicle accident sustained injuries including intracranial hemorrhage, BAI, and extremity fractures. Immediate neurosurgical intervention was required. Once neurologically stabilized, endovascular repair was performed with a commercially available device modified with a custom fenestration to preserve flow into the left SCA. Serial follow-up CT angiography (CTA) demonstrates satisfactory repair with prograde left SCA flow and no evidence of endoleak. Conclusion: Left SCA coverage is often required for successful endovascular repair of BAI. A subgroup of patients who undergo left SCA coverage will require revascularization. The use of custom fenestrated endografts for preserving left SCA during thoracic endovascular aortic repair (TEVAR) for BAI is an innovative and feasible option in patients who require revascularization.
