Rotational atherectomy in restenotic lesions at the distal saphenous vein graft anastomosis.
Restenotic lesions at distal saphenous vein graft (SVG) anastomoses have been notoriously difficult to treat with standard angioplasty techniques. We explored the potential of rotational atherectomy in three patients with nonthrombotic, focal restenoses at the SVG touch down. The Rotablator safely and successfully recanalized the lesions, allowing further treatment with dilation or stenting or both. Rotational atherectomy may warrant investigation as a treatment for nonthrombotic restenotic SVG lesions.
