摘      要:Objective To observe the immediate angiographic and intravascular ultrasound (IVUS) results and their effects on one month clinical outcomes in forty one patients who submitted to coronary stent deployment with IVUS guidance Methods All patients were allocated to coronary stent implantation with high inflation pressure After good angiographic results (20% residual stenosis), all patients underwent IVUS and higher pressure dilatation would be necessary if criteria for optimal coronary stent implantation were not met The optimal criterion of IVUS for stent implantation was the ratio of intrastent lumen cross sectional area to the average of the proximal and distal reference lumen cross sectional areas ≥80% All patients had aspirin and ticlopidine therapy on the day of angioplasty and during the one month follow up period Results Optimal criteria of IVUS were obtained without any further intrastent dilatation in twenty five patients but intrastent higher pressure dilatation was performed in fourteen patients whose ultrasound results did not reach the criteria In these patients, we increased the minimal intrastent lumen area 25 7% ( P 0 05) Thirty five patients (90%) had good minimal intrastent lumen area of IVUS There were no deaths, myocardial infarction, acute stent thrombosis or need for revascularization during the study and the one month follow up Conclusions Intracoronary stent deployment under IVUS guidance, including combining aspirin and ticlopidine therapy, had beneficial ultrasound results and good clinical outcomes after one month follow up
