Endovascular stent graft repair of abdominal aortic aneurysms: Current status and future directions

Figure 14 Computational fluid dynamic analysis of the interference of suprarenal stent struts with renal blood flow shows the flow velocity calculated in a realistic aorta model without placement of suprarenal stent struts (A), with simulated stent wire thickness of 0. 4 mm (B), 1.0 mm (C) and 2.0 mm (D). The laminar flow pattern from pre-stent grafting was found to change to turbulent with simulated stent struts across the renal arteries, with flow velocity decreased up to 30% when the wire thickness increased to 2.0 mm.
