It was reported by the provider that the patient's right ijv vein was accessed easily with the needle with excellent blood return.The micro-wire was advanced assuring bevel in the "up" position.The wire was then found to be coiled in the vein so was withdrawn.On withdrawal, the wire "jammed" in the needle.The needle was then backed out slowly as the wire would not move and the wire was dissected free from any surrounding tissue directly at the puncture.Despite all efforts the wire refused to budge.Eventually with time and effort the wire came loose and the outer "wrap" of wire was found to be frayed and separated from the wire core.When the wire was able to be withdrawn, it was noticed a portion of the wire was missing and retained in the patient.Ultrasound and flouro were used to confirm this, and the fragment appeared to be stuck in a vein valve.An attempt to remove the fragment was made via cut down, however, it was unsuccessful as it was stuck in the tissue and risk outweighed the benefit of removing.It was reported the fragment would most likely not be removed from the patient in the future.
