Double Fenestrated Physician-Modified Stent Graft for Endovascular Treatment of Traumatic Aortic Isthmus Rupture With an Aberrant Right Subclavian Artery

Abstract

Purpose: The purpose of the study was to demonstrate the feasibility of urgent endovascular treatment of a traumatic aortic isthmus rupture in a patient with an aberrant right subclavian artery. Case report: A 23-year-old man was admitted to a regional trauma center after a motor vehicle collision and found to have cerebral trauma and a large pseudoaneurysm of the aortic arch. Trauma computed tomography (CT) identified a blunt traumatic thoracic aortic injury with an aortic false aneurysm in the context of an aberrant right subclavian artery. A hybrid repair was performed with bilateral subclavian carotid bypasses and a double fenestrated physician-modified stent graft. The patient had an uneventful postoperative course. Postoperative CT scan showed sealing of the aortic arch rupture and patency of all the supra-aortic trunks. Conclusion: Endovascular repair of blunt traumatic thoracic aortic injury is considered first-line therapy. Aortic arch anomalies add complexity to treatment. This report demonstrates that a hybrid strategy with bilateral carotid-axillary bypasses and homemade double fenestrated endograft of the aortic arch is a valuable approach for this challenging emergency in the context of an aberrant right subclavian artery.
