血管内超声在冠脉介入中的应用进展

冠脉造影是诊断及治疗冠心病最有价值的方法。由于冠状动脉解剖结构的特殊性及冠脉病变的多样性，冠脉造影检查对于冠脉病变的评估已不足以满足临床需要，随着冠脉支架植入技术的发展及成熟，随之出现支架贴壁不良及支架内血栓形成，使患者再次面临急性心血管事件风险概率增加。因此，在冠脉造影中应用血管内超声检查已成为冠脉介入手术的热点，其能充分评估冠脉管壁、管腔及病变性质，有利于病情的充分评估及支架选择、支架释放的应用。该文就血管内超声在冠脉介入手术中的临床应用进行综述。

Application of intravascular ultrasound in percutaneous coronary intervention

Coronary angiography is the most valuable method in the diagnosis and treatment of coronary heart disease. For the special structure of the coronary artery anatomy and the diversity of coronary artery lesion, coronary angiography for the assessment for coronary artery disease has been insufficient to meet clinical needs, besides, with the development of coronary stent technology, the emergence of poor adherence of the stent and stent＇thrombosis increases, the patients will suffer from major cardiovascular events. Therefore, the application of intravaseular ultrasound in coronary interventional procedures has become a hot spot. The intravascular ultrasound applied in coronary interventional procedures are reviewed in this article.
