Stent Graft Simulation

Keywords: Stent Graft, Aneurysm, Stenosis, Simulation, Abdominal Aortic Aneurysm (AAA), Carotid

Endovascular treatment of stenosis and aneurysms has been practiced since the early 1990’s. In contrast to open surgery, only a small cut is needed to insert the stent prosthesis, which can mostly be done under local anesthesia. Since it is not possible to change the stent during treatment, endovascular therapy requires information about the individual vascular dimensions prior to an operation, so that a suitable stent can be chosen.

In general, the folded stent is inserted from the femoral artery until it is placed in the stenosis or the aneurysm. Then, the stent is expanded and opens the artery (stenosis) or splints the vessel walls to protect it from rupturing due to blood pressure (aneurysm). This form of therapy is less stressful on the patient than open surgery and also suitable for high risk patients who are not eligible for open surgery. Clinical studies have shown that the results of this kind of minimal invasive surgery are comparable to open surgery.

Our research project focuses on the simulation and visualization of stent grafts in arteries with aneurysms, e.g. abdominal aortic aneurysms (AAA), thoracic aortic aneurysms (TAA), iliac aneurysms and stenosis, e.g. carotid stenosis. Based on this simulation, physicians are supported in choosing a stent before an intervention. This is very important because a stent which has not the exact dimensions could shift or cover an artery branch. In the long term, we hope to contribute to reducing the mortality rate by a more precise planning of the endovascular surgery based on precise preoperative vessel measuring and stent simulation.
