Abstract: Objective The purpose of this study is to evaluate simulation based courses to enhance the technical performance and interest level of clinical medical undergraduate students in vascular surgery. Method A total of 41 undergraduate clinical medical students who interned in our department from October 2020 to March 2022 were included in the interest survey and pre tested on an intravascular simulator. During the internship, I guided simulator courses on a weekly basis and completed the final testing on the simulator. The simulator determines Objective procedures before and after testing, and vascular surgery teachers use a structured global evaluation scale to score subjective performance. After the course, the students received a survey of opinions on vascular surgery as a career choice. Finally, six months after the course ends, a survey will be conducted again among all students to determine their interest in vascular surgery. Results In terms of diagnostic time, stent deployment time, and fluoroscopy time, there was a significant statistical difference (P<0.05). At the same time, there was also a significant statistical difference in stent release effect indicators (P<0.05). More than 95% of students reported that intravascular simulators have increased their knowledge and interest in vascular surgery. Conclusion Receiving guidance on endovascular surgery on a simulator can have a positive impact on the attitude of clinical medical undergraduate students towards vascular surgery. Simulator based courses may be an important component of vascular surgery training programs.
