METHODS: The patient was admitted due to fever, cough, and expectoration symptoms. Previously, the patient had undergone a procedure of percutaneous coronary stent implantation in our hospital\'s cardiology department, which led to a gradual rise in blood eosinophil count. This time, the eosinophil count was higher than the previous admission. A chest CT scan revealed multiple flocculent density increases in both lungs and bronchiectasis. The rapamycin-eluting stents may have caused eosinophilia and interstitial pneumonia, which improved after administering corticosteroids. A systematic review of relevant literature was conducted to summarize the characteristics of interstitial pneumonia caused by drug-eluting stents.
CONCLUSIONS: Paclitaxel, everolimus, zotarolimus, and rapamycin are the types of drugs that can lead to drug-eluting stents, and because of the rarity of their onset, clinical doctors must be precise and prompt in diagnosing suspected cases to avoid misdiagnosis and delayed treatment.
方法:患者因发热入院,咳嗽,和咳痰症状。以前,患者在我院心内科接受了经皮冠状动脉支架植入术,导致血液嗜酸性粒细胞计数逐渐上升。这一次,嗜酸性粒细胞计数高于之前的入院.胸部CT扫描显示肺部和支气管扩张中的多个絮凝密度增加。雷帕霉素洗脱支架可能引起嗜酸性粒细胞增多和间质性肺炎,服用皮质类固醇后有所改善。系统复习相关文献,总结药物洗脱支架所致间质性肺炎的特点。
结论:紫杉醇,依维莫司,佐他莫司,雷帕霉素是可以导致药物洗脱支架的药物类型,因为它们很少发作,临床医生在诊断疑似病例时必须准确及时,以避免误诊和延误治疗。
