The treatment of type A acute aortic dissection is a challenge for the surgeon, and serious late complications may occur even after surgical repair. We report treatment after a type A postdissection thoracoabdominal aneurysm in a patient who previously underwent ascending aortic reconstruction using a biological aortic valve and Dacron prosthetic graft implantation in emergency conditions. The multistaged approach involved removing the right kidney and performing a heterotopic autotransplantation in the left iliac fossa before positioning a fenestrated endograft (celiac trunk, superior mesenteric artery, and left renal artery). The final step should have been the implantation of an aorto-bifurcated endograft, which, however, was postponed because the patient was injured during rehabilitation therapy. After 12 months, the computed tomography angiography scan showed complete thrombosis of the false lumen associated with large iliac entry tear closure and aortic diameter stability. These findings prompted us to desist from completing the aorto-bi-iliac implantation. This case demonstrates that in selected patients in whom treatment of a postdissection thoracoabdominal aneurysm with fenestrated endoprosthesis requires a challenging revascularization of the renal artery, a heterotopic kidney transplant using a mini-invasive technique may represent a viable and sufficiently safe alternative that guarantees renal blood perfusion.
