title: Supercath Safety Clampcath buttonhole creation: complication of catheter breakage.
abstract: The creation of buttonhole tracks with Supercath Safety Clampcath is a novel and simple technique that allows dull fistula needle insertions with relative ease and diminished pain. As greater experience with this procedure develops, new issues arise for consideration. We report an unexpected complication of Supercath Safety Clampcath catheter breakage that may be due to physical distortions as a result of its location in the antecubital fossa just proximal to the elbow joint. We present a review of our experience and a framework for the safe ongoing use of this device for creation of buttonholes in fistula for hemodialysis.
