title: Placement of "biliary" stents in saphenous vein coronary bypass grafts.
abstract: Angioplasty of coronary saphenous vein grafts has been associated with less favorable results than in native coronary arteries owing to a higher acute complication rate and an increased incidence of restenosis. We placed 16 nonarticulated balloon expandable stainless steel "biliary" stents at the sites of 13 stenotic or occluded aortocoronary saphenous vein graft lesions in 11 patients. All of the lesions were stented successfully. There were no instances of stent thrombosis or stent embolism. The percent diameter stenosis was reduced from 85.5 +/- 14.1% to 3.5 +/- 4.4% (p < .001), and the minimal lumen diameter of the lesion increased from 0.7 +/- 0.7 mm at baseline to 3.7 +/- 0.2 mm (p < .001) after stent placement. We conclude that this noncoronary stent appears to be safe and effective for treating saphenous vein coronary bypass grafts. The high procedural success rate and excellent angiographic results are very encouraging, while the restenosis rates remain to be determined.
