a pea in the pod nursing bra 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 partial crushing of the left common carotid bridging grafts was observed on computed tomography angiography.

This was treated by reinforcing the branch with 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 ultimate warrior hat inner branch arch repair of residual type A chronic dissection.
