摘要：Computational fluid dynamics analyses were performed on three models which have a giant aneurysm with or without a stenosis. The first is a model with an aneurysm (no stenosis and no stent), the second is a model with a preaneurysm stenosis, and the third is a model with an aneurysm implanted with a stent. The increase in pressure in aneurismal sac caused by a 50% stenosis is about 10.3mmHg at peak systole ( comparison between the second model and the first model). It must pay attention to the increase of the pressure for the patient which has an aneurysm accompanied by a stenosis when making the treatment plan. Otherwise, it may cause the aneurysm rupture.
