Virtual stent-graft planning: numerical simulation of the endovascular repair of abdominal aortic aneurysms

我们正在开发一种软件，用于模拟医疗器械如何用于腹主动脉瘤（AAA）的腔内修复术，腹主动脉瘤的特征是肾动脉下方的主动脉膨胀。其目的是预测被称为支架移植物（SG）的血管假体的部署，作为一种比经典的“开放”手术侵入性更小的替代方案，在传统的“开放”手术中，患者的腹部被打开，假体直接缝合在主动脉中。在任何情况下，这样的血管假体将动脉囊排除在血压之外，从而限制了破裂的风险。

We are developing a software to simulate how a medical device is used in the endovascular repair of abdominal aortic aneurysms (AAA) which are characterized by a ballooning of the aorta below the renal arteries. The objective is to predict the deployment of vascular prostheses called stent-grafts (SG) introduced with catheters, as a less invasive alternative than the classic "open" surgery in which the patient's abdomen is opened and the prosthesis stitched directly in the aorta. In any case, such vascular prostheses exclude the aneurismal sac from blood pressure, thus limiting the rupture risk.
