Educational Impact of a 3D Canine Vascular Simulator for Learning Anatomy and Interventional Radiology Techniques in...

Simulation-based teaching is increasingly important in veterinary training, especially for learning anatomy and interventional techniques where real-life exposure is limited.

A handcrafted 3D simulator replicating the canine abdominal arterial system was developed and tested with 80 veterinary students and graduates. A quasi-experimental pre-post design evaluated theoretical knowledge, practical skills, and self-perceived competence after a structured training session including anatomical identification, catheter navigation, and the Seldinger technique.

Post-training results showed significant improvements in all domains. Theoretical test scores increased by over 25% (p < 0.001), and more than 85% of participants correctly identified target arteries after training. Navigation success rose to 90%, with shorter execution times and fewer errors. Participants reported increased confidence and satisfaction with the realism and educational value of the simulator.

The 3D vascular simulator effectively enhanced learning outcomes and confidence in interventional radiology. Its low-cost, handcrafted design makes it a feasible and valuable educational tool for veterinary institutions lacking access to high-fidelity commercial simulators.
