Fig 3.

Representative flow simulation results of a patient treated with a 26-mm ZFEN graft. The calculated aortic and arterial branch pressure are displayed at the model inlets and outlets. Red lines depict flow waveforms and blue lines depict pressure waveforms. The dotted line depicts the preoperative results and the solid line depicts the postoperative results. In this patient, increased peak pressure and peak flow were observed in the bilateral renal arteries and proximal and distal aorta, whereas a decreased peak pressure and flow was observed in the superior mesenteric artery and celiac arteries after fenestrated endovascular aneurysm repair (fEVAR).
