In-utero stenting: Development of a low-cost high-fidelity task trainer

Abstract

Objective: To develop an in-utero stent placement training model. Methods: The in-utero stent task trainer was constructed using a formalin-preserved gravid pig uterus. Altering the size of the uterine segment, changing the fluid level in the uterus and addition of a large Ziploc freezer bag variably filled with differing amounts of ultrasound gel can vary the procedural skill required. Results: Thoracoamniotic and vesicoamniotic shunts can be simulated using this life-like model. The cost of eight to 10 learning stations is approximately US $60. Fetal position, maternal size and amniotic fluid status can be altered rapidly to increase the complexity of the procedure. Conclusions: This low-cost and realistic task trainer can provide the opportunity to practice in-utero shunt procedures in a non-clinical environment. This model should enhance learning and reinforce acquired skills. Copyright © 2009 ISUOG. Published by John Wiley & Sons, Ltd.
