Chronic restenosis of venous stents are the most challenging situations in the venous field. Instent material could be rock hard. Even that we have no dedicated venous techniques available to cross and debulk these lesions, we could use very efficient devices with arterial indication. The case example below shows our current Arnsberg strategy to recanalize these chronic restenotic venous stents:
1. Poking with the GOBACK catheter needle deeply into the hard occlusion cap.
2. Advance wire with support catheter
3. Debulking
4. Balloon angioplasty
5. Realign with Blueflow Venous stent

There is of course room for technical improvement and innovation in this field
