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(in-travascular 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.
Abstract
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,in-complete 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 positio-ning 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.
