Background: A successful case of urgent type II thoracoabdominal aneurysm repair with an inner branched endograft conducted entirely through femoral accesses without the bailout possibility to achieve an upper extremity approach for bridging stents delivery is described. Case report: A 70-year-old male patient underwent hybrid treatment for a thoracic aortic aneurysm on complicated type B dissection in 2 steps. First, arch debranching with carotid-carotid-subclavian bypass and then ascending aortic replacement with reimplantation of the anonymous trunk plus TEVAR were performed. The scheduled 1-month control computed tomography angiography (CTA) showed a rapid increase of the false lumen thoracoabdominal aneurysm, with axial diameter measuring more than 10 cm. The repair procedure was based on the use, as off-the-shelf graft, of a prosthesis customized for another patient with inner branches for visceral vessels that well suited the characteristics of the case. A steerable guiding sheath was essential to stabilize the system in the selective and sequential cannulation of 2 of the 4 inner branches (for celiac trunk and superior mesenteric artery) and to complete the bridging stents deployment. Procedure was carried out without complications. Conclusions: In an urgent setting, total endovascular correction of a thoracoabdominal aortic aneurysm exclusively through femoral accesses appears to be feasible when the appropriate tools are available.

Abstract

Background: A successful case of urgent type II thoracoabdominal aneurysm repair with an inner branched endograft conducted entirely through femoral accesses without the bailout possibility to achieve an upper extremity approach for bridging stents delivery is described. Case report: A 70-year-old male patient underwent hybrid treatment for a thoracic aortic aneurysm on complicated type B dissection in 2 steps. First, arch debranching with carotid-carotid-subclavian bypass and then ascending aortic replacement with reimplantation of the anonymous trunk plus TEVAR were performed. The scheduled 1-month control computed tomography angiography (CTA) showed a rapid increase of the false lumen thoracoabdominal aneurysm, with axial diameter measuring more than 10 cm. The repair procedure was based on the use, as off-the-shelf graft, of a prosthesis customized for another patient with inner branches for visceral vessels that well suited the characteristics of the case. A steerable guiding sheath was essential to stabilize the system in the selective and sequential cannulation of 2 of the 4 inner branches (for celiac trunk and superior mesenteric artery) and to complete the bridging stents deployment. Procedure was carried out without complications. Conclusions: In an urgent setting, total endovascular correction of a thoracoabdominal aortic aneurysm exclusively through femoral accesses appears to be feasible when the appropriate tools are available.
