ObjectiveTo explore the application effects of 3D printing technology combined with multimedia teaching based on CT angiography(CTA) data source in the teaching of abdominal aortic dilatation diseases.
MethodsFrom April to October 2020, a total of 60 doctors with master degree in vascular surgery, regulatory affairs trainee and undergraduate interns from the First Affiliated Hospital of Bengbu Medical College were selected, and divided into the observation group and control group according to the random number allocation method(30 cases in each group).Four typical abdominal aortic dilatation cases treated with vascular interventional therapy in hospital were selected, and detected using CTA before operation.The 1∶1 solid model was made by 3D printing technology according to CTA data.The control group was taught with the traditional multimedia teaching method, while the observation group was taught with multimedia instruction combined with 3D printing technology based on CTA data source.
ResultsThe total score in observation group was higher than that in control group(P < 0.05).The test scores of abdominal aortic anatomy, interventional therapy for dilated aortic diseases, indications and contraindications in observation group were significantly higher than those in control group(P < 0.05).The understanding the anatomical structure of vascular system, understanding the characteristics of aortic dilated disease, understanding the instruments and procedures of endovascular surgery, learning initiative and confidence in observation group were better than those in control group(P < 0.05).The satisfaction of the observation group was 90.00%, which was higher than that of the control group(60.00%)(P < 0.05).
ConclusionsThe 3D printing technology combined with multimedia teaching based on CTA data source in the teaching of abdominal aortic dilatation disease can significantly improve the students' academic performance and satisfaction.It has a good application effect, and is suitable for promotion.
