The aim of this case report was to present an endovascular treatment of a residual post-dissection Crawford type III thoracoabdominal aneurysm (TAA). A 60-year-old man, who had suffered from acute type B aortic dissection (TBAD) 8 years ago and had already been treated for both descending thoracic and infrarenal aortic aneurysm with open repair, presented with a 61mm post-dissection TAA. The aneurysm was successfully excluded with a staged fully endovascular procedure by employing two multibranched custom-made stent grafts deployed into the false lumen. The first stent-graft with a proximal monobranch was created to perfuse the right renal artery via the true lumen. The latter, with a triple branch design, was meant to perfuse the visceral arteries and left renal artery arising from the false lumen. Available branched custom-made stent-grafts for the treatment of degenerative TAA can be employed also in post TBAD aneurysms so as to simplify the procedure. The branched stent-grafts could be deployed within an enlarged false lumen provided that a suitable distal landing zone is available as well as that the visceral vessels can be perfused from the false lumen. A proximal branch for perfusing one of the lumens of the dissection from the proximal tear can be an alternative solution to creating neofenestrations.

Abstract

The aim of this case report was to present an endovascular treatment of a residual post-dissection Crawford type III thoracoabdominal aneurysm (TAA). A 60-year-old man, who had suffered from acute type B aortic dissection (TBAD) 8 years ago and had already been treated for both descending thoracic and infrarenal aortic aneurysm with open repair, presented with a 61mm post-dissection TAA. The aneurysm was successfully excluded with a staged fully endovascular procedure by employing two multibranched custom-made stent grafts deployed into the false lumen. The first stent-graft with a proximal monobranch was created to perfuse the right renal artery via the true lumen. The latter, with a triple branch design, was meant to perfuse the visceral arteries and left renal artery arising from the false lumen. Available branched custom-made stent-grafts for the treatment of degenerative TAA can be employed also in post TBAD aneurysms so as to simplify the procedure. The branched stent-grafts could be deployed within an enlarged false lumen provided that a suitable distal landing zone is available as well as that the visceral vessels can be perfused from the false lumen. A proximal branch for perfusing one of the lumens of the dissection from the proximal tear can be an alternative solution to creating neofenestrations.
