Renal perfusion with venous blood extends the permissible suprarenal clamp time in abdominal aortic surgery  Maximilian Pichlmaier, MA, MD, Ludwig Hoy, PhD, Mathias Wilhelmi, MD, Nawid Khaladj, MD, Axel Haverich, MD, Omke E. Teebken, MD  Journal of Vascular Surgery  Volume 47, Issue 6, Pages 1134-1140 (June 2008) DOI: 10.1016/j.jvs.2008.01.020 Copyright © 2008 The Society for Vascular Surgery Terms and Conditions

Fig 1 The change in renal function with the operation is shown as a function of suprarenal clamp time and renal perfusion in patients (A) with no perfusion and (B) those with perfusion. A, Renal function deteriorates with clamp time if there has been no perfusion, and this is highly significant. B, This relationship, however, is lost if perfusion is performed.

Fig 2 The rise in C-reactive protein (CRP) after the operation is shown as function of suprarenal clamp time and renal perfusion in patients (A) with no perfusion and (B) those with perfusion. There is interdependence of CRP and suprarenal clamp time, but only for the patients without renal perfusion.
