Off-the-shelf fenestrated endografts: a realistic option for more than 70% of patients with juxtarenal aneurysms.
Journal of Endovascular Therapy 2012 April
PURPOSE: To evaluate the suitability of a standardized fenestrated endograft in patients with juxtarenal abdominal aortic aneurysms.
METHODS: High resolution computed tomographic angiograms from 100 consecutive patients (96 men; mean age 72 years) with juxta- (n = 78) and pararenal (n = 22) aneurysms treated electively between 2005 and 2010 with custom-made fenestrated endografts were reviewed. A centerline of flow reconstruction was carried out in a 3D imaging workstation to precisely define the aortic morphology, including aortic diameters and distances between visceral and renal arteries. The applicability of 2 different "off-the-shelf" standardized fenestrated endografts designed by the manufacturer was evaluated in this cohort. Both designs included 2 fenestrations for the renal arteries, 1 for the superior mesenteric artery (SMA), and a scallop for the celiac trunk. The designs differed in the lengths of the SMA to renal fenestration and renal to renal fenestration.
RESULTS: Endovascular treatment with one or both "off-the-shelf" endografts was deemed possible in 72 patients (56 with design 1, 52 with design 2, and 36 with both endografts). Of the 28 patients who were not candidates for a standardized fenestrated stent-graft of either design, the primary cause was a right renal artery that did not match the position of its corresponding fenestration.
CONCLUSION: Standardized fenestrated designs suitable for endovascular treatment of >70% of patients with juxta- and pararenal aneurysms currently treated with custom-made fenestrated endografts will soon be available. This new generation of endografts will permit rapid treatment of a large majority of patients requiring fenestrated endograft repair.
