Renal function after aortic stent-grafting including XXXX .

@entity1 @entity8 @entity449 @entity177 @entity1011
Considerable experience has been gained with endoluminal stent-graft techniques for the treatment of @entity449 . The inclusion of uncovered suprarenal stents eases the treatment of cases with a short, angulated, or bottlenecked proximal neck. However, few data have been published on the effect of a stent-graft crossing renal artery ostia on long-term renal function. We therefore retrospectively analyzed the influence of intra-aortic stent-grafts, including suprarenal fixation on long-term renal function. Thirty-nine @entity1 who received a Gianturco Z stent across renal artery ostia as part of a made-to-measure stent-graft treating an @entity449 were evaluated at 6 (all @entity1 ) and 30 months (15 @entity1 ) after surgery. Renal function evaluation included serum @entity1011 level, @entity1011 clearance using the Cockcroft-Gault formula, and renal tomography. Initial technical success was achieved in all @entity1 . There were no minor or major complications. Mean serum @entity1011 levels were 1.16 +/- 0.25, 1.12 +/- 0.28, and 1.24 +/- 0.25 mg/dL before and 6 and 30 months after endoluminal stent-graft performance, respectively (P = not significant [NS]). Mean @entity1011 clearances were 60.3 +/- 19.7, 63 +/- 23, and 60.6 +/- 17.5 mL/min before and 6 and 30 months after endoluminal stent-graft performance, respectively (P = NS). Only two @entity1 (5%) had a decrease in glomerular filtration rate greater than 20% at 6 months. Both @entity1 had @entity177 before endovascular grafting. Renal function was stable in all @entity1 at 30 months' follow-up. We suggest that renal function is unaffected by @entity8 with Gianturco Z stents.
