Three-channeled aortic dissection successfully excluded via false-lumen thoracic endovascular repair

Abstract

Three-channeled aortic dissection is a rare, high-risk condition that often arises as a late complication of a prior aortic dissection. However, open surgery and conventional trans-true lumen thoracic endovascular aortic repair (TEVAR) are challenging, owing to aortic fragility and complex anatomy. The present report describes the case of a 74-year-old man with a three-channeled thoracoabdominal aortic dissection who was successfully treated with short stent-graft implantation into the false lumen to seal the secondary entry. This approach resulted in effective thrombosis of the secondary false lumen and preserved visceral perfusion, with no remote aortic-related events observed during 1 year of follow-up. This report highlights the feasibility of trans-false lumen TEVAR as an alternative strategy in anatomically favorable cases.
