Although uncommon, a trapped central venous catheter (CVC) can present a significant problem for the interventionalist and pose considerable risk to the patient. The use of chronic long-term CVCs is on the rise, with an average catheter dwell time of 10 months. Although all CVCs are prone to complications, chronic catheters exhibit a higher rate of complications. Chronic catheters are also at risk of becoming trapped, whereby they cannot be removed by standard technique. A simple, elegant technique to remove a trapped CVC via inserting an angioplasty balloon into the lumen of a stuck catheter has been described, as has a modified technique with inclusion of a hemostatic sheath and a stiff guidewire inserted into the cut catheter to ensure hemostasis, prevent air embolism or endoluminal thrombosis, and avoid injury to the central veins and heart. Examples of both applications are provided in this chapter.
