Objective　To evaluate 3D printing abdominal aortic aneurysm model in analysis of clinical teaching effect for standardized resident doctors in vascular surgery department. Methods　48 resi-dents in vascular surgery department in our hospital from December 2016 to September 2017 were seleeected and randomly divided into control group and the experimental group. The traditional vascular surgical anatomy atlas

ultrasound

CT abdominal blood vessel 3D reconstruction

digital subtraction

video and so on were used by 24 residents in the control group

while in the experimental group

on the basis of the traditional teaching

abdominal aortic aneurysm model of 3D printing

true aortic coated stent delivery system were increased. After the teaching

the theory of evaluation (abdominal vascular anatomical features

morphological characteristics and classification of AAA

measurement of various parameters and key points of operation in the EVAR) and satisfaction questionnaire were adopted to evaluate the effect of two kinds of teaching methods. SPSS 19.0 was used to conduct t test on two groups of physician evaluation data. Results The results of theoretical assessment showed that there was no significant difference between the control group and the experimental group in the abdominal vascular anatomical features

the morphological features and the classification of the experimental group (P>0.05) in the examination of the common AAA cases and the complicated AAA cases. However

the experimental group was higher than the control group in the mea-surement of the parameters of EVAR

and the score of the operation points and the total score

and the difference was statistically significant (t=2.283

t=2.263

P<0.05). The results of the questionnaire showed that the students' satisfaction scores on the teaching satisfaction of the normal and complex AAA cases were better than those of the control group

and the difference was statistically significant (P<0.05). Conclusion　The 3D printing model can increase the understanding and mastery of the anatomy and treat-ment of abdominal aortic aneurysm and improve its learning enthusiasm for vascular surgery. We should make full use of the advantages of 3D printing technology on the basis of retaining the advantages of tradi-tional teaching methods and means

and further enhance the teaching effect.
