Case Study: Houston Methodist Hospital achieves realistic patient-specific FEVAR hands-on training with 3D Systems' 3D-printed aortic models

Realistic FEVAR Hands-On Training Made Possible with 3D Printed Aortic Model

3D Systems worked with vascular surgeons from Houston Methodist and Stanford to tackle the challenge of training clinicians in complex fenestrated endovascular aortic repair (FEVAR) for abdominal aortic aneurysms that involve arteries to the kidneys and intestines. Traditional training methods offered limited realism for the precise measurements, anatomy interpretation and device handling required to preserve vital branch blood flow during stent-graft implantation.

The solution used patient CT data to produce pliable, latex-like 3D-printed aortic models hooked to a circulatory pump to recreate physiologic conditions, allowing trainees to perform the full OR procedure on lifelike anatomy. Participants reported accurate device tracking and realistic feel, enabling repeated hands-on practice, patient-specific rehearsal and tool customization, and supporting a blended reality training approach that enhances surgical planning and education.
