Blood Flow Velocity Prediction in Aorto-iliac Stent Grafts Using Computational Fluid Dynamics and Taguchi Method

Covered Endovascular Reconstruction of Aortic Bifurcation (CERAB) is a new technique to treat extensive aortoiliac occlusive disease with covered expandable stent grafts to rebuild the aortoiliac bifurcation. Post stenting Doppler ultrasound (DUS) measurement of maximum peak systolic velocity (PSVmax) in the stented segment is widely used to determine patency and for follow up surveillance due to the portability, affordability and ease of use. Anecdotally, changes in haemodynamics created by CERAB can lead to falsely high PSVmax requiring CT angiography (CTA) for further assessment.
