Clinicsl research of Palmaz-Schatz stent implantation

Objective To evaluate the clinical efficacy of Palmaz-Sctatz(P-S)stent,and sum up the experience of P-S stent implantation.Methods The P-S stent were implanted in 79 patients with 85 coronarylesions.According abscences of in hospital death.emergency coronary arterybypass grafting(CABG),Q wave myocardial infarctina(MI)or repeatintervention,measured the primary successfui rate of stent implantation atpostoperatively and the bail out rate of acute coronary closure afterpercutaneous transluminal coronary angioplasty(PTCA).Clinical follow upin 74 of 82 lesions of successful stent implantation was obteined at 3-6month after operation,the restnotic rate was measured by quantitativecoronary angiography.The restenosis was defined as】50% diameterstenosis at follow up.Results In 79 patients with 85 coronary lesion.82 were successfulimplanted.the successful rate was 96%.The Q wave MI 2 patients andemergency CABG 1 patient in 3 patients of unsuccessful stent implantation,and that have not death and repeat interveation.The 28 patients weredelivered in 31 patients with acute coronary closure after PTCA.The bailout rate was 90%.12 have restenosis in 82 lesions of follow up at 3-6month after stent implantation,the restenotic rate was 16%.Conclusion The successful rate of P-S stent implantation was high.andthe occur rete of major adverse events was lower than other stents.Thebail out rate was high in acute coronnry closure after PTCA.The restenotierate at 3-6 month after stunt implantation has lower than other stents.Butthe P-S stent yes not suitable for medium winding blood vessel and was
