In-stent restenosis is a difficult percutaneous scenario if calcific neoatherosclerosis is the underlying aetiology.
A 69-year-old diabetic woman with a previous percutaneous coronary intervention on the left anterior descending coronary artery was readmitted for non-ST-elevation myocardial infarction. In-stent restenosis due to calcific neoatherosclerosis was observed by intracoronary imaging during the intervention. Intravascular lithotripsy was used successfully to fracture the underlying calcific plaque. However, the balloon ruptured during treatment although this did not damage the artery.
Intravascular lithotripsy is a promising tool for the treatment of extremely calcified lesions including calcific neoatherosclerosis of in-stent restenosis. Balloon rupture is a complication of this new percutaneous treatment that has not previously been described.
如果潜在病因是钙化性新动脉粥样硬化，支架内再狭窄是一种棘手的经皮治疗情况。
一名69岁的糖尿病女性，既往曾对左前降支冠状动脉进行过经皮冠状动脉介入治疗，因非ST段抬高型心肌梗死再次入院。介入治疗期间通过冠状动脉内成像观察到由钙化性新动脉粥样硬化导致的支架内再狭窄。血管内碎石术成功用于破碎潜在的钙化斑块。然而，治疗期间球囊破裂，尽管未损伤动脉。
血管内碎石术是治疗极度钙化病变（包括支架内再狭窄的钙化性新动脉粥样硬化）的一种有前景的工具。球囊破裂是这种新型经皮治疗的一种并发症，此前尚未见报道。
