Staged endovascular repair of post-dissection thoracoabdominal aortic aneurysm using false lumen stent grafts placement.

We report a false lumen stent graft technique to close the intimal tears at the visceral segment for post-dissection thoracoabdominal aneurysm after initial thoracic endovascular aortic repair. Following abdominal endovascular aortic repair, a stent graft was then deployed in the false lumen, and successfully closed the intimal tears at the visceral segment. The residual re-entries at the iliac level were closed 2 years after the prior endovascular aortic repair, once a collateral network for spinal cord perfusion had developed, minimizing the risk of spinal cord ischemia. This endovascular strategy successfully reduced a size of post-dissection thoracoabdominal aneurysm.
