Title
Three-dimensional aortic aneurysm model and endovascular repair: An educational tool for surgical trainees
Abstract
OBJECTIVES: Endovascular aortic aneurysm repair (EVAR) is a
current valid treatment option for patients with abdominal aortic
aneurysms (AAAs). The success of EVAR depends on the selection
of appropriate patients, which requires detailed knowledge of the
patient’s vascular anatomy and preoperative planning. Threedimensional
(3D) models of AAA using a rapid prototyping technique
were developed to help surgical trainees learn how to plan for
EVAR more effectively.
METHOD: Four cases of AAA were used as prototypes for the models.
Nine questions associated with preoperative planning for EVAR
were developed by a group of experts in the field of endovascular surgery.
Forty-three postgraduate trainees in general surgery participated in the present study. The participants were randomly assigned into two
groups. The ‘intervention’ group was provided with the rapid prototyping
AAA models along with 3D computed tomography (CT) corresponding
to the cases of the test, while the control group was provided
with 3D CTs only.
RESULTS: Differences in the scores between the groups were
tested using the unpaired t test. The mean test scores were consistently
and significantly higher in the 3D CT group with models
compared with the 3D CT group without models for all four cases.
Age, year of training, sex and previous EVAR experience had no
effect on the scores.
CONCLUSION: The 3D aortic aneurysm model constructed using
the rapid prototype technique may significantly improve the ability
of trainees to properly plan for EVAR.
