Event Description
|
A physician implanted an abre self-expanding stent for the treatment of a fibrous lesion with chronic total occlusion in the distal region of the superior vena cava (svc).There were no issues noted when removing the device from the hoop/tray.There was mild tortuosity and severe calcification.The device was prepped as per the ifu with no issues identified.The procedure began with access through left sided port.They passed a non-medtronic wire (amplatz) wire easily through the stenosis in the svc after placing a 9fr sheath.The physician predilated the ends of the stenosis with a non-medtronic 16fr (atlas) balloon, however, didn't predilate the actual compression point as they didn't want to predilate the tight compression with concerns the stent would then watermelon seed forward and we would lose accuracy.They had a 12 and 16 non-medtronic balloons (atlas) in the room to post dilate after stent deployment.Post deployment when attempting to walk the delivery system off the wire, difficulties removing the device were encountered and the nose cone of the stent was stuck beyond the tight compression.They unknowingly pulled the system out, but the nose cone and shaft were left behind in the body with the shaft extending out of the sheath.The stent has caught upon the stent during withdrawal.They then attempted to pass an 018 from the neck, however it couldn't pass.We then got femoral access to attempt to snare the nosecone from the bottom.We were eventually successful.A 018 wire was put down the shaft/nosecone of the foreign body in order to preserve access through the stent.Once the foreign body was removed, a non-medtronic balloon (035 quick cross) was used and then were able to post dilate the stent to the correct size and the subsequent venogram was perfect.No resistance was not encountered when advancing the device excessive force used, the device pass through a previously-deployed stent.No further patient injury reported for this event.
