摘　　要：冠状动脉造影一直以来不仅是诊断冠心病的金标准,而且也用来指导冠状动脉介入治疗。但冠状动脉造影往往会因为一些客观因素,特别是在复杂的三维解剖学上的平面分辨率有限,术者凭借视觉评估病变的真实面积和长度的可靠性有限,以及在检测钙化方面的敏感性较低等,对术者术中的治疗决策会产生不可避免的误导。而血管内超声可通过提供冠状动脉的断层或横断面图像来指导冠状动脉治疗,目前已成为一种在复杂病变患者中获得更好的支架植入效果的重要方法,与单独的冠状动脉造影相比,具有更好的临床效果。Coronary angiography has always been a gold standard for the diagnosis of coronary heart disease and also used to guide coronary interventional therapy.However,coronary angiography is often limited due to some objective factors,especially the limited planar resolution in complex three-dimensional anatomy,and the limited reliability of visual assessment of the true size and length of the lesion,and the low sensitivity in detecting calcification will inevitably mislead the surgical decision-making.Intravascular ultrasound can guide coronary artery therapy by providing sectional or cross-sectional images of the coronary artery.Currently,it has become an important method to obtain better stent implantation effect in patients with complex lesions,and has better clinical effect compared with coronary angiography alone.
