title: Outcomes of a Percutaneous Technique for Shortening of Totally Implanted Indwelling Central Venous Chest Port Catheters.
abstract: Central venous port catheters that are too long are typically removed or revised. The subcutaneous position of port reservoirs precludes standard over-the-wire exchange techniques, and a method of percutaneous revision using an intravascular loop snare technique has been previously described. A retrospective review was conducted of 38 procedures that were performed at a single academic institution between 2005 and 2015. Technical success was 100%, without immediate or delayed complications with follow-up until port removal or death in 94% of patients. Percutaneous revision is an effective method for shortening too-long port catheters, allowing uninterrupted use of the port.
