| Research Abstract |
Anew approach using the technology of solid-liquid interaction model to estimate the risk of aneurysm rupture was performed under hemodynamic conditions. Flow energy loss in aneurysms was significantly different between ruptured-aneurysms and stable-aneurysms. The preliminary study found that greater energy loss occurred when flow passed through ruptured aneurysms, when compared to unruptured aneurysms. This new concept of energy loss may become a useful tool for the prediction of aneurysm rupture. These preliminary results indicated that EL may be a useful parameter for the quantitative estimation of the risks of rupture for aneurysms.
