本文报告了一例76岁男性患者，因多次静脉和动脉注射碘对比剂后发生反复迟发型过敏反应（DHRs）。该病例突显了DHRs的结构依赖性、不同碘对比剂之间可能存在的交叉过敏风险，以及针对高风险患者制定个体化治疗方案的重要性，警示临床加强碘对比剂迟发型过敏反应的早期识别和标准化预防性处理措施具有重要意义。
This article reports a case of a 76-year-old male patient who experienced recurrent delayed-type hypersensitivity reactions (DHRs) following multiple intravenous and arterial injections of iodine contrast agents. This case highlights the structure-dependent nature of DHRs, the potential risk of cross-sensitivity between different iodine contrast agents, and the importance of developing individualized treatment plans for high-risk patients. It underscores the significant clinical importance of strengthening early identification and standardized preventative management of delayed-type hypersensitivity reactions to iodine contrast agents.
