Visceral and Renal Tissue Oxygenation During Supraceliac Aortic Crossclamping and Left Heart Bypass with Selective Organ Perfusion

Abstract

LHB and SOP preserves renal but not visceral tissue oxygenation during supraceliac aortic crossclamping and does not induce hemolysis.

Renal Perfusion During Aortic Surgery: Looking for the Ideal Substrate

“…However, these disappointing results with roller pump are in contrast with those reported by Idu, again in a porcine model, with selective renal blood perfusion instituted with a centrifugal pump [14]. In this study, adequate renal perfusion volumes without significant hemolysis and effective renal tissue oxygenation were reported during supraceliac aortic cross-clamping [14].…”

The impact of selective visceral perfusion on intestinal macrohemodynamics and microhemodynamics in a porcine model of thoracic aortic cross-clamping

“…Therefore, there are little data to compare with the current study. Idu et al 18 recently assessed the effect of a left heart bypass and selective organ perfusion during supraceliac and infrarenal aortic cross-clamping on tissue oxygenation in a pig model. They detected a reduced blood flow in the major visceral arteries during SVP that was paralleled by a strong decrease in the mixed oxygen saturation in the visceral vascular bed, while the median O 2 ER and jejunal PCO 2 increased.…”

“…[18][19][20] Furthermore, the vascular anatomy of these animals (vessel origins and caliber) is very similar to the human anatomy. Thus, it is feasible to use the same technical equipment as applied in human major aortic surgery to establish an ECC, such as a standard roller pump, standard cannulas and catheters, and tubing systems.…”

Microcirculatory perfusion shift in the gut wall layers induced by extracorporeal circulation

“…Visceral perfusion by means of DAP or DAP with SVP is used to provide volume-controlled and pressurecontrolled blood flow to abdominal organs, aiming for prevention of intestinal injury. 15 Whereas SVP did not provide sufficient blood flow and pressure in the visceral arteries, 16 DAP establishes adequate flow rates and mean arterial blood pressures in these vessels.…”
