Résumé
<p><b>OBJECTIVE</b>To evaluate the early clinical result of percutaneous transluminal coronary intervention (PCI) and stenting on saphenous vein grafts.</p><p><b>METHODS</b>Percutaneous intervention was performed in 91 saphenous vein grafts in 64 patients. The data of clinical results during operation and hospitalization and that of other interventional assisting device were recorded in database and were analyzed.</p><p><b>RESULTS</b>The success rate of operation was 95.3%, non-Q wave myocardial infarction occurred in 1 patient (1.6%) and temporary no-reflow phenomenon occurred in 4 patients (6.3%) during operation. Reduced antegrade flow and ventricular fibrillation happened in 1 patient after stenting and normal antegrade flow obtained after cardiac compression and tracheal intubation and insertion of IABP. The distal protection devices were used in 7 patients (10.9%), X-sizer extraction system in 4 patients. Platelet glycoprotein IIb/IIIa receptor blockers were administered in 25 patients (35.9%). Non-Q wave myocardial infarction occurred in two cases, the incidence of major adverse clinical event was 3.1% during the period of hospitalization.</p><p><b>CONCLUSIONS</b>The instant success rate of PTCA and stenting of saphenous vein bypass grafts is high and recent clinical result is promising, but the middle and long term results remain to be further followed. The use of distal embolic protection device and GPIIb/IIIa receptor blockers may improve its prognosis.</p>
