Methods: 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. Results: 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. Conclusions: 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.2025http://zaguan.unizar.es/record/16579910.3390/vetsci12121139http://zaguan.unizar.es/record/165799oai:zaguan.unizar.es:165799info:eu-repo/grantAgreement/ES/DGA/B36-23Rinfo:eu-repo/grantAgreement/ES/DGA-FEDER/Construyendo Europa desde AragónVeterinary Sciences 12, 12 (2025), 1139 [17 pp.]byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
