摘　　要：钙化病变增加了冠心病介入治疗的难度,增加了围术期及长期并发症风险,钙化病变的预处理非常重要,经皮冠状动脉腔内冲击波球囊导管成形术(IVL)在钙化病变中使用越来越多,众多临床试验证明了其对钙化病变的有效性和安全性。支架膨胀不全是支架内血栓形成和支架内再狭窄的重要危险因素,增加并发症发生率,目前对于钙化病变导致的支架膨胀不全的处理并无有效应对策略,也无明确的相关共识或指南。关于IVL治疗支架膨胀不全报道较少,且多为个案报道、小样本研究。本文报道了2例患者,支架置入后发现膨胀不全,采用IVL进行处理,取得较好效果。Calcified lesions increase the difficulty of interventional therapy for coronary heart disease,and increase the risk of perioperative and long-term complications.Pretreatment of calcifi ed lesions is very important.Coronary lithotripsy(IVL)is used more and more in calcifi ed lesions,and many clinical trials have proved its effectiveness and safety.Stent underexpansion is an important risk factor for stent thrombosis and restenosis,which increases the incidence of complications.At present,there is no eff ective coping strategy or clear consensus or guidelines for the treatment of stent underexpansion caused by calcifi ed lesions.There are few reports about the treatment of stent under expansion by IVL,and most of them are case reports and small sample studies.In this paper,two cases of stent under expansion were reported.After stent implantation,stent under expansion was found,and IVL was used to treat the cases,which achieved good results.This paper reports 2 cases of stent under expansion to explore the effi cacy and safety of IVL in the treatment of such lesions.
