Endovascular technique for revision of excess catheter length in subcutaneous implanted venous access devices

To describe the implementation of a technique to trim the excess length of a central venous catheter via a process of endovascular snaring without exposing or changing the device. We report on the outcome of this technique in 3 patients. The technique was successful in two cases and successful with a modification in the remaining case. The technique is useful to salvage an implanted venous access device. It appears to be less invasive with reduced procedure time and less patient discomfort than other techniques.
