In order to prevent acute vessel closure and restenosis after percutaneoustransiuminal coronarg angioplesty(PTCA).36 intracoronarystents wereimplanted into 33 vessels in 30 patients aged 32-72 years with cororary heartdisease.20 patients had unstable angina,7 old myocardial infarction and 3acute myocardial infarction.Single vessel tesion was detected in 20 patients.double vessel lesion in 6 and triple vessel lesion in 4.23 stents wereimplanted in LAD,3 in LCX and 10 in RCA.Those stants include 17 Nirstents,8 Palmaz-Schatzstents and 11 Gianturco-Roubin stems.The meaninflation pressure was15+1.2 ATM.The procedure success rate was 100%.Thediarneter stenosis reducad from 87±11.9% to 5±9.8% after stenting.Thecombined use of aspirin and ticlopidine was a main anticoagulation therapy inour group.there were no complicatins such as acute or subacute thrombosis.cerebral bleeding,myocardial infarction,in-hospital death or emergencyCABG.Most patients were free from ischemic symptoms during 1 to 20 monthsfollow-up.There were two patients whose angina pectoris recurred in 6 monthof stenting,one was cured with repeat PTCA and the other with CABG.The results suggest that intracoronary stenting is an effective and safe methodfor vessel disection or acute closure following PTCA.It has high successrate and low restenosis rate.High pressure inflation for optimal stentdeployment,careful assessment of final angiographic result with near zeroresidual stenosis and the association of aspirin/ticlopidine can effectivellyprevent thrombosis and do not increase bleeding complications in themeantime.
