Hybrid Repair of an Aberrant Right Subclavian Artery with Kommerell's Diverticulum

Abstract 

This publication describes a hybrid endovascular and open surgical approach to treating a large aneurysm of an aberrant right subclavian artery (Kommerell's diverticulum). A 76-year old man presented with dysphagia lusoria due to a 3.5 × 3.0 cm aneurysm involving an aberrant right subclavian artery. The patient was treated by a thoracic aortic endograft, left subclavian artery de-branching (by its transposition to the left common carotid artery) and right subclavian artery revascularisation. This approach avoids the requirement for a thoracotomy or sternotomy needed with open surgical repair. At a 6 months follow-up assessment the aneurysm was shown to be thrombosed with no evidence of endoleak.
