    Abstract
  •   Objective  To study the effect of 3D printing technology combined with problem-based learning (PBL) teaching mode in the teaching of aortic dilation disease for clinical undergraduates and residents.  Methods  A total of 64 undergraduates and 42 residents who studied in our center from January 2019 to February 2020 were randomly divided into control groups and experimental groups according to odd or even number by drawing lots. The traditional teaching model was used in the control group (32 undergraduates and 21 residents), and 3D-printed models and PBL were added to the traditional teaching model in the experimental group (32 undergraduates and 21 residents). After teaching, the effectiveness of the two methods was evaluated using tests and practical examination.  Results  Regarding the teaching of undergraduates, the performance of the experimental group was better than that of the control group in terms of aortic anatomy and basic theory, typing and characteristics of abdominal aortic aneurysms, and practical examination (localisation and puncture of the femoral vascular, all P < 0.05). Regarding the teaching of residents, no statistical difference existed between the aortic anatomy and the basic theoretical in two groups (all P>0.05). The teaching performance of the experimental group was better in terms of type and endovascular treatment measurement, operation points, and characteristics of complicated abdominal aortic aneurysms (all P < 0.05) during the teaching of common cases and complicated cases.  Conclusion  The application of 3D-printing technology and PBL enables undergraduate students to better master the basic theories of aortic dilatation diseases and the key points of vascular puncture operation. Residents can improve the identification and treatment of aortic dilated diseases and enhance the teaching effect of aortic dilatation diseases.
