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. ? 2019 World Scientific Publishing Company.
