Several illustrations showing stenosis and occlusion of the lower limb arterial axes. From left to right : -a human outline showing the location of stenosis areas at the aortic bifurcation and the iliac artery. -An anatomical view of the location of the stenosis or occlusion at the aortic bifurcation and the iliac artery. -Close-up of the stenosis or occlusion at the aortic bifurcation and the primitive iliac artery. -Areas that make up the occlusion : occlusion of the femoral artery (yellow area), occlusion of the femoral and popliteal artery (pink area) and occlusion of the tibial and peroneal arteries (blue area).
