    Abstract:
    To assess whether a staged strategy (initial stand alone transluminal extraction atherectomy and coumadin therapy followed by stenting six weeks later) could reduce ischemic complications in degenerated saphenous vein graft (SVG) interventions, we studied 72 patients undergoing percutaneous interventions of degenerated SVG. Patients were divided into two groups; 28 were treated with a staged strategy (group I) and 44 with similar lesion characteristics were treated with a definitive initial procedure with transluminal extraction atherectomy +/- adjunctive balloon angioplasty and stenting (group II). Procedural success, major in-hospital complications (death, Q-wave myocardial infarction, and emergent coronary bypass surgery), and incidence of distal embolization were compared between the 2 groups. Procedural success was lower (92% vs 100%, p = 0.14) and major in-hospital complications were higher (0% vs 11%, p = 0.14) in group II. Distal embolization occurred in 11% of the patients in group I compared with 23% of the patients in group II (p = 0.19). At 6 week follow-up (group I), 9 patients (33%) had negative symptoms, 11 (41%) underwent stent implantation, 3 (11%) did not require any further therapy (without significant stenosis), and 4 (14%) had total occlusions. We therefore conclude that this staged strategy in degenerated SVG appears to reduce distal embolization but most importantly avoids major in-hospital complications, including any deaths either at the time of initial procedure or during the 6-week follow-up period.
