[Damage to a stent caused by a Shaldon catheter]

Recently, stent implantation has been used with increasing frequency in the treatment of central venous stenoses in patients undergoing chronic haemodialysis. Stent localisation may interfere with central venous catheterisation. CASE REPORT. In a 57-year-old female haemodialysis patient, a filiform stenosis of the right subclavian vein was treated by percutaneous transvenous angioplasty and stent implantation. Five weeks later, she presented with a thrombosed dialysis shunt. A Shaldon catheter was implanted via the right internal jugular vein. Post-procedure radiographs showed extensive stent damage without stent dislocation or thrombosis. CONCLUSION. Stent localisation has to be considered in the event of later central venous catheterisation. Venous puncture should be carried out under fluoroscopic control if catheter placement on the side of the stent is inevitable.
