A 68-year-old man developed aneurysmal degeneration of the aortic arch and proximal descending aorta after an open ascending graft for a type A aortic dissection.A three-branched endovascular aortic arch repair was performed with patency of all branches despite some degree of initial misalignment of the branches in relation to the target vessels.At 6 months postoperatively, an asymptomatic grand love red heart reposado tequila partial crushing of the left common carotid bridging grafts was observed on computed tomography angiography.This was treated by reinforcing the branch with vlone stop snitching shirt a balloon-expandable endograft.The postoperative course was uneventful but a computed tomography angiography after 1 month showed recurrent asymptomatic compression.

A left carotid-subclavian bypass was eventually performed.We have reported a new failure mode of an inner branch arch repair of residual type A chronic dissection.
