Is catheter rupture rare after totally implantable access port implantation via the right internal jugular vein? Report of a case.

Catheter rupture after totally implantable access port (TIAP) implantation via the right internal jugular vein is thought to be very rare. We report a case of catheter rupture found 682 days after TIAP surgery in a 52-year-old woman with recurrent right breast cancer. It is possible that chronic stress at the flexure of the catheter induced by neck movements caused the catheter to rupture. Therefore, when inserting a TIAP via the right internal jugular vein, the site of venous puncture should be decided on carefully. Although a fracture of this type is rarely reported in the literature, the incidence of catheter injury of a TIAP inserted via the internal jugular vein at our institute is 1.8 %. This highlights the need to educate and caution medical staff and patients about preventing catheter fracture being caused by external factors.
