We presented a multimodal imaging approach to identifying aortic arch aneurysm with a concurrent coarctation of the aorta in a 52-year-old woman. We successfully adopted a new operative method and described the management of whole process. The detailed imaging and intraoperative data have not been reported in the literature before. This case highlighted the feasibility and successful surgical intervention in a patient with coarctation of the aorta and a concurrent enormous aortic arch aneurysm. An extra-anatomical bypass is an innovative surgical technique that is proved effective and beneficial.
