1 Effect of suprarenal versus infrarenal aortic endograft fixation on renal function and renal artery patency: a comparative study with intermediate follow-up  L.Louis Lau, MD, Albert G Hakaim, MD, W.Andrew Oldenburg, MD, Beate Neuhauser, MD, J.Mark McKinney, MD, Ricardo Paz- Fumagalli, MD, Andrew Stockland, MD  Journal of Vascular Surgery  Volume 37, Issue 6, Pages (June 2003) DOI: /S (03)

2 Fig 1 Zenith modular bifurcated endograft. Note suprarenal uncovered stent crossing renal artery ostia. Journal of Vascular Surgery  , DOI: ( /S (03) )

3 Fig 2 Axial contrast-enhanced CT scans of one of two patients with preexisting renal artery stenosis. A, Scan obtained before EVAR shows patent renal arteries and contrast uptake by kidneys. B, Scan obtained 1 month after endografting. Left kidney is atrophic, with nonfilling of the left renal artery compared with normal sized right kidney with widely patent right renal artery. Journal of Vascular Surgery  , DOI: ( /S (03) )

4 Fig 3 Box and whisker plot of serum creatinine concentration. *P = .045, †P = .008, group 1 vs group 2. Open circles, Extreme values; open boxes, group 1 (infrarenal fixation); solid boxes, group 2 (suprarenal fixation). Journal of Vascular Surgery  , DOI: ( /S (03) )

5 Fig 4 Estimated creatinine clearance, Cockcroft-Gault formula. P = .121, Wilcoxon rank-sum test, group 1 vs group 2. Open boxes, Group 1 (infrarenal fixation); solid boxes, group 2 (suprarenal fixation). Creatinine clearance = [(140 − age) × weight]/(SCr × 72) for men or [(140 − age) × weight]/(SCr × 85) for women.
