Abstract

PurposeTo evaluate the usefulness of a tool that we developed to simulate performance of insertion and retrieval of optional inferior vena cava filters to be additionally used in training of beginners with an animal model.Subjects and methodsThirty young doctors who had little or no experience in insertion and/or retrieval of filters were subjects of this study to evaluate the training tool. Eleven trainees practiced both insertion and retrieval of filters first with the animal model then with the blood vessel model while 19 trainees first practiced with the blood vessel model then with the animal model.ResultsAll trainees successfully inserted the filter. Two of the 11 trainees who used the animal model before the blood vessel model failed in retrieval, and 2 of the 19 trainees who used the blood vessel model before the animal model failed. In the former group, mean time for filter implantation and withdrawal in the animal model was 75 ± 62 s and 341 ± 238 s, respectively, and in the latter group were 54 ± 16 s and 311 ± 236 s, respectively.ConclusionTraining with the combination of a blood vessel model and animal model is helpful for beginners to learn to insert and withdraw optional filters.

Highlights

In the current medical training program in Japan, we have increasing numbers of trainees rotating through radiology departments in university or academic hospitals, including medical students and junior and senior residents
Filters were successfully inserted into the inferior vena cava in the animal model by all 30 trainees with a mean time of 62 ± 40 (SD) s
Second trainee who trained with trainee who trained with animal model first blood vessel model first (n=11)

Summary

Introduction

In the current medical training program in Japan, we have increasing numbers of trainees rotating through radiology departments in university or academic hospitals, including medical students and junior and senior residents. For beginners in interventional radiology, the Japan Society of Interventional Radiology has been holding a hands-on seminar annually to teach procedures that are considered necessary for interventional radiologists. This year insertion and withdrawal of optional filters were themes of this seminar. The training program included use of a combination of a blood vessel model, which was originally designed to simulate performance of insertion and withdrawal of filters, and an animal model. The purpose of the present study was to evaluate the educational effect of this program from a technical perspective and the role of training with a blood vessel model in addition to that with an animal model
