Successful Endovascular Repair of a Kommerell's Diverticulum and a Right-Sided Aortic Arch

Abstract

Background: A 57-year-old woman was diagnosed with Kommerell's diverticulum in the setting of a right aortic arch on computed tomography. Case report: Although asymptomatic, the maximum diameter of the aneurysm was 55 mm; thus, she underwent surgery to prevent rupture of the aneurysm. A bypass was constructed from the left common carotid artery to the left subclavian artery. A stent-graft was deployed from the distal right subclavian artery, and coil embolization of the diver-ticulum was performed via the left subclavian artery. She was discharged after 12 days of surgery. The postoperative four-month follow up showed a smaller aneurysm. Conclusion: Thoracic endovascular aortic repair is feasible and effective for Kommerell's diverticulum.
