Review of the events surrounding the incident were conducted and review with the surgeon involved.We have concluded that this incident involved a possible defective/malfunction catheter.As described by the surgeon, the procedure of the catheter exchange over a wire (if possible) the surgeon would withdraw the catheter 2cm and then cut the catheter at the level that was previously below the skin.In this fashion, the surgeon would not exchange a wire through a catheter that has been exposed outside of the patient's body.After cutting the catheter, the surgeon advanced the wire through the catheter and removed the remainder of the catheter.The surgeon had a clamp on the catheter and cut it.At no time did the surgeon lose sight of any portion of the catheter.However, looking inside the catheter; there's a different color lining in the catheter that the surgeon was not used to seeing.This is not the type of catheter the surgeon usually exchanges.A pair of forceps was used to pick up the lining but, it felt completely attached to the inside of the catheter.The surgeon then exchanged the catheter over the wire.The surgeon advanced the new catheter over the same wire.The final fluoroscopic images did not show any foreign body.The lower half of the catheter which was removed directly over the wire appeared to be intact.At the time that occurred, it seemed that this was a different type of catheter with a different lining in it.It did not occur to the surgeon that this could be a faulty catheter.The surgeon went back and review the x-ray and believes the portion of the catheter that was left inside was present on the postop chest x-ray and all subsequent x-rays.It was hard to differentiate the retained foreign body from the left-side triple lumen catheter which was also placed at the same time as the surgery.Fda safety report id# (b)(4).
