It was reported that the procedure was to treat a chronic totally occluded lesion in the anterior tibial artery.A whisper guide wire failed to cross due to the anatomy.About 10cm of the tip wire broke off in the anatomy during removal and the broken tip twisted, which made it impossible to remove from the anatomy, even after several attempts to snare.The tip was left in the patient and the anterior tibialis was not re-vascularized.The procedure was completed.No additional information was provided.
