Abstract 14097: A 3D Print Low Cost Aortic Arch Endovascular Simulator

Abstract

Introduction: Simulation-based medical teaching and learning enables trainees to gain competencies in a realistic setting without imposing risks to patients. Within endovascular training, simulations improve patient safety and decrease health care costs. Access of the aortic arch from a femoral puncture site is a key competency in the endovascular field. Here, we show how a low-cost artificial vascular simulator enables accurate replicated catheterization of the aortic arch. Hypothesis: Methods: Digital Imaging and Communications in Medicine (DICOM) data extracted from a computed-angio tomograph (CTA) using an image processing software was selected to include the arterial region of interest. A mold was made with plastisol from the printed 3D toolpath (Fig. 1). After maturation of the mold, the separate sections were assembled into the simulator (Fig. 2). Results: Data extracted from a CTA was processed to create a vascular model that was accessed using an arterial access kit, and guided under fluoroscopy, a radiopaque catheter was navigated to the aortic arch. The total consumable cost of the simulator was U$194.64. Conclusions: In this proof-of-concept study, we demonstrate the process of producing a low-cost 3D printed artificial vascular simulator made from 3-D printing and image examination. This simulator faithfully replicated the endovascular access of the aortic arch from a femoral puncture site. We recognize the scalability of our technique and its possibility of assisting in endovascular navigation of various interventional radiology procedures in a patient specific manner.
