It was reported that the endovascular stent graft was used to cover a stenosis in the femoral vein in the outflow of a leg graft as a previously placed stent graft had migrated to the outflow vein.Reportedly, difficulties were experienced during deployment of the endovascular stent graft.Subsequently, a pta balloon was used for post-dilation and the tip of the balloon caused the endovascular stent graft to move forward.An angioplasty was performed by using the same pta balloon to complete the procedure.There was no reported patient injury.

The lot records have been reviewed with special attention to the manufacturing and inspection of this product and the product was found to have met all specifications prior to shipment.No sample was returned.As part of all complaint investigations, an attempt was made to evaluate the subject device as well as the device usage.Potential factors which may have caused or contributed to the reported issue have been considered.As this reported event is an isolated incident no previous investigations of similar complaints could be reviewed.The reported difficult stent graft deployment as well as the reported entrapment of the balloon tip which led to stent graft movement may be associated with a difficult patient anatomy.A manufacturing related cause has also been considered.In this case no sample and no images were provided for evaluation and therefore, no deficiency could be determined which may have led to the reported event.On the basis of the information available and as no sample was returned, a definite root cause for the reported event could not be determined.The ifu states: "if unusual resistance or high deployment force is encountered during stent graft deployment, abort the procedure, remove the delivery system and use an alternative device of the same size." regarding the anatomy of the placement site the ifu states: "the safety and effectiveness of the device when placed across a tight bend (.) has not been evaluated.Prior to stent graft deployment, ensure that the proximal (inflow) stent graft end is positioned in a straight section of the lumen to reduce the risk of higher deployment forces and possible endovascular system failure." furthermore, the ifu states: "examine the packaging and endovascular system to determine if there is any damage, defects or if the sterile barrier is compromised.Do not use the device if any of these conditions are observed.".
