摘　　要：支架膨胀不全是冠状动脉介入过程中相对常见的情况。严重的支架膨胀不全会导致支架内再狭窄、支架内血栓形成及支架断裂等严重后果,越来越多的医师认识到识别和处理危及患者生命的支架膨胀不全尤为关键。腔内影像学对于指导冠状动脉介入过程中如何预防支架膨胀不全有重要作用。近期相关研究阐释了震波球囊、准分子激光、冠状动脉斑块旋磨术等技术处理支架膨胀不全的可行性。本文将从支架膨胀不全的病理生理机制、腔内影像评估以及处理等方面做一综述,以供冠状动脉介入医师参考。Stent under-expansion is a relatively common situation during coronary intervention procedure,which can lead to serious consequences such as stent restenosis,stent thrombosis and stent rupture.How to early identify and deal with stent under-expansion has achieved widespread attention in recent years.Intraluminal imaging guided percutaneous coronary intervention plays an important role in the prevention of stent under-expansion.Besides,recent studies have demonstrated the feasibility of shockwave balloon,excimer laser coronary atherectomy and rotational atherectomy in dealing with stent under-expansion.This paper reviews the pathophysiology,intraluminal imaging evaluation and management of stent under-expansion to provide a reference for coronary intervention.
