Aneurysm case 1. Columns left to right: prestent, no oversize, 0.5-mm oversize, and 1.0-mm oversize. Rows top to bottom: vascular model and details of stent cells at the aneurysm neck, isovelocity surfaces, velocity-colored flow streamlines, and wall shear stress distribution (all at peak systole).

Aneurysm case 2. Columns left to right: prestent, no oversize, 0.5-mm oversize, and 1.0-mm oversize. Rows top to bottom: vascular model and details of stent cells at the aneurysm neck, isovelocity surfaces, velocity-colored flow streamlines, and wall shear stress distribution (all at peak systole).

Aneurysm case 3. Columns left to right: prestent, no oversize, 0.5-mm oversize, and 1.0-mm oversize. Rows top to bottom: vascular model and details of stent cells at the aneurysm neck, isovelocity surfaces, velocity-colored flow streamlines, and wall shear stress distribution (all at peak systole).

Reduction of hemodynamic measures (inflow rate, mean velocity, mean shear rate, and mean wall shear stress) from the prestenting condition obtained with flow-diverting devices with no oversize (denoted +0.0 mm), 0.5-mm oversize, and 1.0-mm oversize in 3 patient-specific aneurysm geometries (denoted aneurysms 1, 2, and 3). Blue bars correspond to flow condition 1, and red bars, to flow condition 2. Solid bars show reduction in time-averaged quantities, while error bars correspond to maximum and minimum reductions obtained during the cardiac cycle.
