摘　　要：经皮冠状动脉介入(percutaneous coronary intervention,PCI)治疗开口病变时常需要支架精确定位。支架突入过多将导致再次介入困难、远期血栓和支架内再狭窄等不良事件发生,但由于开口解剖位置变异、造影剂显影不完全和限制血流等原因,常导致近端支架边缘位置无法清晰识别。本文报道采用血管内超声(intravascular ultrasound,IVUS)实时定位指导支架定位治疗左主干病变2例,发现IVUS较多体位冠状动脉造影更为高效、精准地识别近端支架落脚点,且显著降低造影剂和放射线用量。The percutaneous coronary intervention(PCI)in coronary ostium lesion often requires precise stent implantation.Excessive stent protrusion will lead to adverse events such as difficulty in re-intervention,long-term thrombosis,and in-stent restenosis.However,due to the variation of the anatomical position of the ostium,incomplete image display,limited blood flow,and so on,the operator is sometimes unable to identify the position of the proximal stent edge during angiography.Here,we used the intravascular ultrasound(IVUS)real-time positioning guided stent implantation for two left main lesion patients,and found that the IVUS real-time guidance is more efficient than multi-position coronary angiography,and more accurately identifies the proximal stent edge,and significantly reduce the dose of contrast medium and radiation.
