Percutaneous transluminal angioplasty of an in-stent re-stenosis of the right subclavian vein in a dialysis patient
Patient Data
High grade in-stent restenosis. There are multiple collateral veins filling in in this venogram.
Post balloon angioplasty - good lumen restoration and disappearance of collateral venous filling.
Case Discussion
Central venous stenosis is a relatively common problem in patients on long term haemodialysis through an AV fistula in the upper limb and may be seen in up to 40% of patients.
The clinical presentation may vary - poor flow rates at dialysis needing longer hours of dialysis, limb swelling etc.
Interventional radiology offers a good option of management of such cases either by percutaneous transluminal balloon angioplasty or stent placement. Post stenting there is a risk of in-stent restenosis due to high flows at the dialysis and at the AV fistula. In-stent restenosis can be treated by balloon angioplasty.
This case demonstrates the use of balloon angioplasty in treating in-stent restenosis.
