Objectives: Blunt thoracic aortic injuries (BTAIs) involving the aortic arch are a challenging condition. Thoracic endovascular aortic repair (TEVAR) with fenestration, which expands the proximal landing zone, is able to exclude the injury while preserving blood flow in supra-aortic branches.
Methods: Here we report a case of TEVAR with fenestrations of all supra-aortic branches for traumatic aortic pseudoaneurysm and perform a systematic review.
Results: A 24-year-old man suffering a blunt thoracic injury and a left femoral fracture was sent to our hospital. A pseudoaneurysm was found in the aortic arch between the brachiocephalic artery and the left common carotid artery. The patient underwent emergent TEVAR with fenestrations of all supra-aortic branches, which excluded the pseudoaneurysm and preserved the patency of all branches. The orthopedic team then treated the femoral fracture. The patient's recovery was unremarkable. We performed a systematic review on TEVAR with fenestrations for BTAI. Six patients (75%) received TEVAR with single fenestration, 1 patient (12.5%) received TEVAR with two fenestrations, and 1 patient (12.5%) had fenestrations of all supra-aortic branches. Except one patient died in the perioperative, other patients survived without stent-related complications in the short-term follow-up.
Conclusions: TEVAR with fenestration is feasible for treating BTAI involving the aortic arch in selected patients.
