Abstract
Purpose
To demonstrate transapical stent-graft implantation for the treatment of an ascending aortic aneurysm simultaneously using the “periscope” technique for all supra-aortic branches.
Technique
The treatment plan is demonstrated in a 67-year-old man with prior ascending aortic replacement and known ascending aortic aneurysm who presented with acute severe chest pain. Computed tomographic angiography (CTA) revealed an 11-cm ruptured aneurysm of the ascending aorta distal to the prosthesis. Surgery was impossible due to direct contact of the aneurysm with the sternum. Conventional retrograde stent-graft implantation was infeasible because of a sharp kink of the descending thoracic aorta, so the stent-grafts were implanted via a transapical approach. To provide blood flow to the supra-aortic branches, periscope grafts oriented from the target vessels down the descending thoracic aorta were implanted in all branches before main stent-graft placement. Completion angiography and subsequent CTA documented satisfactory retrograde perfusion of the supra-aortic branches via the periscope grafts.
Conclusion
A dual approach in terms of transapical stent-graft implantation and the periscope technique for perfusion of the supra-aortic branches may be an option for the treatment of inoperable aneurysms of the ascending aorta.
