Thoracic endovascular aortic repair in patients with prior open aortic surgery.

To review our experience of thoracic endovascular aortic repair (TEVAR) in patients with prior open aortic repair (OAR).Stent-grafts were deployed in the arch, descending thoracic and thoracoabdominal aortae of 39, 13 and 5 patients, respectively, and in a deteriorated extra-anatomical prosthesis in one. The access route was the femoral artery in 10 of 23 patients with, and in 30 of 35 patients without a prior abdominal prosthesis. Prior prostheses and elephant trunks comprised 57 of 116 landing zones and 23 proximal landing zones, respectively.Three patients died before discharge. Type II endoleaks developed in six patients, and Types I and III developed in one patient each. Type I endoleaks were not found at landing zones comprising prosthetic grafts. The overall actuarial three-year survival rate including early mortality was 86.5%.The clinical outcomes of TEVAR were excellent, even in patients with prior OAR. Prosthetic grafts, including elephant trunks, provided good landing zones for TEVAR. Prostheses with larger-caliber designs are recommended for iliac artery reconstruction in future TEVAR.
