Uncovered stent-graft in the treatment for residual patent false lumen after surgical repair for acute type A aortic dissection

Abstract

Patent false lumen after surgery for acute type A aortic dissection (AAAD) influences the outcome with increased risk of aortic rupture and visceral malperfusion. We report a case of a patient previously operated on for aortic valve repair and replacement of the ascending aorta because of AAAD, presenting at follow-up with a retrograde dissection in aortic arch, persistent patent false lumen and significative aortic enlargement. An extensive (arch and thoraco-abdominal aorta) successful repair was performed using uncovered stent grafts. We welcome discussion on the real indication of this alternative approach and advantages and disadvantages on mid-/long-term follow-up.
