Safety and 1-year revascularization outcome of SilverHawk atherectomy in treating in-stent restenosis of femoropopliteal arteries: a retrospective review from a single center.

Background: Treatment of in-stent restenosis of the femoropopliteal arteries with balloon angioplasty carries a high rate of recurrence and requires frequent repeat stenting. In the "Instructions for Use," SilverHawk atherectomy (SA) is contraindicated for in-stent restenosis at a peripheral site. SA, however, has a theoretical advantage of reducing the volume of restenotic tissue and potentially delaying the need for frequent repeat revascularization and additional stenting.
