Case
Successful snare retrieval of embolized fragments of central venous catheters in the right heart and pulmonary circulation has been reported [1].
A 70-year-old gentleman with end-stage renal failure on maintenance haemodialysis developed stenosis of the right subclavian vein at the junction of its middle and medial one third following a previous insertion of dialysis catheter through the vein. The stenosis was subjected to percutaneous venous dilatation with placement of an intra-vascular expanding metallic stent (Wallstent 12 mm). There was immediate improvement in his venous oedema. Four months later the chest X-ray showed that the stent had migrated to the right pulmonary artery. Since he remained asymptomatic, a non-intervention policy was utilized. However, he required another intra-vascular stent placement because of recurrence of venous hypertension in that arm 5 months later. He received a cadaveric renal transplantation 2 years later (Figure 1).
