It was reported that the endovascular stent graft migrated following deployment.Therefore, the deployment system was exchanged for a pta balloon which was inflated in an attempt to capture the stent graft and pull it back to the lesion site at the junction of left innominate vein and superior vena cava; however, the stent graft released from the balloon and migrated to the right atrium.The patient had been transferred from the outpatient treatment facility to hospital for surgical removal of the stent graft where it was successfully retrieved via femoral vein cut down.
