The study of patient-specific human arterial flow dynamics is well known to face challenges like a) apt geometric modelling, b) bifurcation zone meshing, and c) capturing the hemodynamic prone to variations with multiple disease complications. Due to aneurysms and stenosis in the same arterial network, the blood flow dynamics get affected, which needs to be explored. This study develops a new protocol for accurate geometric modelling, bifurcation zone meshing and numerically investigates the arterial network with abdominal aortic aneurysms (AAA) and right internal iliac stenosis (RIIAS).

Aortoiliac occlusive disease, or peripheral artery disease affecting the suprainguinal vessels, can lead to a range of clinical symptoms from claudication to more severe, chronic limb-threatening ischemia. Although open surgical reconstruction has traditionally been the reference standard, endovascular options have become significantly more robust in recent years, owing to both improved devices and increasing experience with advanced techniques. This review will discuss the demographics, presentation, and evaluation of chronic aortoiliac occlusive disease, as well as explore the options, both open and endovascular, for revascularization.
