Endovascular Repair of a Penetrating Aortic Ulcer with a Custom-made Relay Stent Graft Featuring a Single Celiac Trunk Fenestration and a Superior Mesenteric Artery Scallop

We report the case of a 70-year-old man with an asymptomatic, fast-growing, paraceliac penetrating aortic ulcer (PAU). Guidelines recommend endovascular repair if an asymptomatic PAU shows a mean growth rate ≥5 mm per year: this patient's maximum aortic diameter was 47 mm but had increased 10 mm in the previous year. The very short sealing zones required a custom-made stent graft. A custom-made relay stent graft comprises a single celiac trunk fenestration, a superior mesenteric artery (SMA) scallop measured according to SMA ostium size, an uncovered distal stent, and 6-mm tapering was used with technical and clinical success.
