A guidewire from a std 4f m.I.Kit 45cm ss/t echo s kit was being used for a ct guided right side chest tube placement.A ct guided chest tube placement into the right pleural space was being performed.When attempting to remove the 0.018 microwire through the micropuncture sheath, tension was felt.The provider attempted to remove the entire setup as one unit due to the tension.At this time, the tip of the guidewire unfurled, and the distal portion fractured off inside the pleural space.During withdrawal of the wire, the tip of the wire detached inside the patient.Attempts were made to remove the fragment, however they were unsuccessful.The fragment remains inside the patient at this time.
