Intravascular disruption of central venous ports.

Intravasal catheter disruption is a rare complication of central venous ports. Main causes are chronic trauma due to compression of the catheter between clavicle and first rib, or primary damage by sharp instruments during insertion. Utilizing the subclavian route, a more lateral insertion can minimize the risk of catheter compression. Regular postoperative X-ray controls can help to recognize progressive catheter compression. In the case of significant compression, early replacement is advisable to avoid disruption. Percutaneous transvenous snare technique is the therapy of choice to retrieve dislocated fragments.
