Abstract

Coverage of the left subclavian artery in thoracic endovascular aortic repair is still a controversial procedure. We report a case of 30-year-old patient with a chronic rupture of the aortic isthmus and short proximal lending zone (10 mm) treated by thoracic endovascular aortic repair using a balloon catheter inflated at the origin of the left subclavian artery (and protruding in the aortic arch) to both preserve the arterial branch patency and fully exploit the proximal neck.
