When treating peripheral artery disease in patients with in-stent restenosis in the femoropopliteal artery, paclitaxel-eluting balloon angioplasty provides significantly higher patency rates than standard PTA. (Paclitaxel Balloon Versus Standard Balloon in In-Stent Restenoses of the Superficial Femoral Artery [PACUBA I Trial] [PACUBA 1]; NCT01247402).

Neointimal proliferation or negative arterial remodeling prevails up to 12 months, and may give rise to rare stent recurrent stenosis. Stent expansion reduces this effect in the first year, and dominates in the second year. This might contribute to the good mid-term outcome of carotid stenting. Poor stent expansion in heavily calcified plaques calls for primary surgical management.

Twelve-month results show that patency was maintained longer after Ranger DCB treatment than after conventional balloon angioplasty, and this result was associated with a low revascularization rate and good clinical outcomes.
