ABSTRACT
Objective The purpose of this study was to determine the feasibility and efficiency of direct stent implantation with intravascular ultrasound (IVUS) guidance Methods 12 native vessel target lesions in 12 patients were studied by coronary angiography and direct stent implantation Ultrasound imagines obtained at the treatment site before and after stenting were analyzed quantitatively for in lesion vessel wall diameter, in lesion minimal lumen diameter and in lesion vessel length Direct stent deployment was performed with IVUS guidance The ends of follow up were acute or subacute thrombosis and major cardiac events (MCE cardiogenic death, angina pectoris, myocardial infarction and revascularization correspondence with target vessel) Results Direct stenting was successfully performed in 12 patients with IVUS guidance Coronary angiography showed that there was no residual stenosis and TIMI 3 flow was obtained in all patients Further balloon dilation of the stent was performed by observation of the IVUS imagines in two patients The final IVUS imagines showed that ratio of minimal lumen diameter/maximum lumen diameter ≥0 7 and in lesion minimal lumen diameter increased from 1 2?0 87 mm to 3 4?2 8 mm No thrombosis and MCE were found in all patients in 1 4 months follow up Conclusion Direct stenting with IVUS guidance in selected patients had higher success rates, less complications and better clinical results:
