This paper investigates the pressure variation in a stented aneurysm complicated by a stenosis. Computational Fluid Dynamics analyses were performed on a giant aneurysm with and without a stenosis. Three models were constructed to compare the pressure variation. Model M1 is the one with an aneurysm (no stenosis and no stent), Model M2 is the one with a preaneurysm moderate stenosis (50%), and Model M3 is the one with an aneurysm implanted with a stent. Pressure increase in the aneurismal sac caused by the stenosis is about 10.3 mmHg at peak systole (comparison between M2 and M1). The pressure increase in the aneurismal sac is about 7.8 mmHg at peak systole (comparison between M3 and M2). The geometry of the parent vessel and its aneurysmal/stenotic disease do have influence on pressure variation.
