The design and development of a simulator for endovascular repair of abdominal aortic aneurysm (AAA) is described. The simulator consists of an interchangeable model of a human AAA based on computed tomography data and is produced by means of computer-aided design and manufacture (CAD/CAM) techniques. The model has renal, iliac, and femoral arteries, and is perfused with a temperature controlled blood-analog fluid under simulated physiological flow conditions. "Fluoroscopic imaging" is simulated by a computerized imaging system that uses visible light. A movable video camera relays images in the antero-posterior and lateral planes of the AAA to a monitor. The imaging system allows "arteriography" and "road-mapping" to be performed so as to facilitate accurate deployment of endovascular stent-grafts. The system has been used for teaching and demonstrating endovascular techniques to clinicians, as well as the evaluation of new stent-graft devices. Its successful incorporation into endovascular workshops has demonstrated its role in the training of clinicians in endovascular repair of AAA.
本文描述了一种用于腹主动脉瘤(AAA)血管内修复的模拟器的设计与开发。该模拟器由基于计算机断层扫描数据的人体AAA可互换模型组成,通过计算机辅助设计与制造(CAD/CAM)技术制作而成。该模型具有肾动脉、髂动脉和股动脉,并在模拟生理流动条件下用温度控制的血液模拟液进行灌注。“荧光透视成像”由使用可见光的计算机成像系统模拟。一个可移动的摄像机将AAA前后和侧面平面的图像中继到监视器。该成像系统允许进行“动脉造影”和“路径图绘制”,以便于准确部署血管内支架移植物。该系统已用于向临床医生教授和演示血管内技术,以及评估新型支架移植物装置。它成功纳入血管内工作坊已证明其在培训临床医生进行AAA血管内修复方面的作用。
