Abstract
A 75-year-old female patient on hemodialysis presented with non-ST-segment elevation myocardial infarction. After successful primary percutaneous coronary intervention, in-stent restenosis (ISR) occurred 3 consecutive times. Intravascular imaging assessment during the repeated percutaneous coronary intervention indicated that the ISR was not associated with neointimal hyperplasia but was mainly attributed to a calcified nodule, which protruded into the lumen. We applied excimer laser catheter ablation to avoid another ISR. ().
摘要
一名75岁接受血液透析的女性患者出现非ST段抬高型心肌梗死。在成功进行初次经皮冠状动脉介入治疗后，支架内再狭窄（ISR）连续发生了3次。在重复经皮冠状动脉介入治疗期间进行的血管内成像评估表明，ISR与新生内膜增生无关，主要归因于一个突出到管腔内的钙化结节。我们应用准分子激光导管消融术以避免再次发生ISR。（）
