From each 10 mm branches, two reverse 14x7 mm bifurcated PTFE prosthetic graft (WL Gore, Flagstaff, Ariz.) were anastomized to both renal arteries and to the celiac axis and superior mesenteric artery, respectively (Fig.2). A CT-scan performed at 6 months follow-up confirmed patency of all prosthetic bypass and re-implanted visceral vessels and complete exclusion of thoracoabdominal aneurysm, (fig.2).
