Type B Aortic Dissection Treated With a Branched Aortic Arch Stent Graft and the STABILISE Technique

We report the case of a 57-year-old woman diagnosed with an asymptomatic chronic type B aortic dissection. The maximum aortic diameter was 70 mm in the proximal descending thoracic aorta. The entry tear was located at the aortic isthmus, and the proximal neck included all of the supra-aortic trunks. The targeted proximal neck was ≥ 25 mm. The dissection extended to the infrarenal aorta. The patient was treated with a custom branched aortic graft with two branches, one for the innominate trunk and one for the left common carotid artery, combined with the stent-assisted balloon-induced intimal disruption and relamination technique. This combined technique seemed to provide a proximal seal zone in the arch and allow remodeling of the distal aorta in this patient with aneurysmal type B aortic dissection.
