Chimney technique for aortic dissection involving an aberrant right subclavian artery

We report a case involving a ruptured acute type B aortic dissection originating from an aberrant right subclavian artery (ARSA). A thoracic stent-graft was deployed in the distal arch close to the origin of the ARSA; the entry site at the origin of the ARSA was embolized with metallic coils. Perfusion of the left subclavian artery was preserved without a surgical bypass by using a chimney graft. This procedure is a feasible and less invasive treatment for high-risk sternotomy patients and is an effective strategy for acute aortic dissections involving an ARSA.
