A novel off-the-shelf single-fenestrated stent graft for emergent complex aortic aneurysm repair.

The off-the-shelf single fenestrated stent graft is based on the Cook Zenith fenestrated platform (Cook Medical Europe) with a premade 8-mm fenestration for the superior mesenteric artery (SMA). The device is suitable for emergency treatment of paravisceral aneurysms when combined with in situ laser fenestration for the renal arteries (and, if required, the celiac trunk). The presence of a premade SMA fenestration results in minimal visceral ischemia time. We present the case of a 69-year-old woman with a ruptured Crawford type I thoracoabdominal aortic aneurysm and a tandem abdominal aortic aneurysm that was treated successfully using the single fenestrated device with in situ laser fenestration for the renal arteries, with no SMA ischemia time. A 6-month computed tomography angiogram showed patent renovisceral stents without an endoleak.
