Optimal renal artery-aorta angulation revealed by flow simulation
Kidney and Blood Pressure Research
Abstract
Introduction
In blood circulation, the vessel branching angle may have hemodynamic consequences. We hypothesized that there is a hemodynamically optimal range for the renal artery branching angle.
Methods
Posttransplant kinetics of eGFR (estimated glomerular filtration rate) data were analyzed regarding the donor and implant sides (right-to-right, left-to-right position) (n=46). The renal artery branching angle from the aorta of a randomly selected population was measured using an X-ray angiogram (n=44). Computational fluid dynamics simulation was used to elucidate the hemodynamic effects of angulation.
Results, and Discussion
Renal transplant patients receiving a right donor kidney to the right side showed faster adaptation and higher eGFR values than those receiving a left donor kidney to the right side (eGFR: 65±7 vs 56±6 ml/min/1.73 m2; P
