Crushing of a bridging stent during follow-up of endovascular branched aortic arch repair: A novel mode of failure

J Vasc Surg Cases Innov Tech. 2022 Aug 7;8(4):646-650. doi: 10.1016/j.jvscit.2022.07.013. eCollection 2022 Dec.

Abstract

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 inner branch arch repair of residual type A chronic dissection.
