Usefulness of beta radiation for de novo and in-stent restenotic lesions in saphenous vein grafts.
Following successful angioplasty of 49 saphenous vein graft lesions, a novel, self-centering phosphorus-32 solid foil beta source encapsulated within a dual-balloon membrane was used to deliver 20 Gy 1 mm into the vessel wall. Clinical and angiographic recurrence rates at 12 months were low, especially in de novo lesions.
