What is the reason for recurrent fever in a patient with a history of thoracic endovascular aortic repair? A woman in her 60s presented with recurrent high fever (>39 °C) and chills for 1 year. She had undergone thoracic endovascular aortic repair for acute type B aortic dissection 9 years ago. Blood cultures returned positive results for Eikenella corrodens. A whole-body scan with [¹⁸F]fluoro-2-deoxy-D-glucose positron emission tomography–computed tomography (¹⁸F-FDG PET–CT) showed abnormal ¹⁸F-FDG accumulation alongside the aortic stent graft, with a maximum standard uptake value of 12.18 (Figure). The patient took intravenous and then oral linezolid for 2 months and then underwent a thoracotomy and replacement of the descending aorta. A culture of resected stent graft confirmed the infection. She recovered well and lived uneventfully after the operation. Aortic graft infection is an unusual, challenging complication of thoracic endovascular aortic repair.¹ The ¹⁸F-FDG PET–CT has emerged as a useful diagnostic modality.^2,3 Wide debridement, graft replacement, and antibiotic use are essential for aortic graft infection treatment.^4,5

有胸主动脉腔内修复术病史的患者反复发热是什么原因？一名 60 多岁的女性出现反复高烧（>39 °C）和寒战 1 年。9 年前因急性 B 型主动脉夹层接受了胸主动脉腔内修复术。血培养对Eikenella corrodens呈阳性反应。^{[ 18} F]fluoro-2-deoxy-D-葡萄糖正电子发射断层扫描-计算机断层扫描 ( ¹⁸ F-FDG PET-CT)全身扫描显示异常¹⁸F-FDG 在主动脉覆膜支架旁积累，最大标准摄取值为 12.18（图）。患者先静脉注射利奈唑胺，然后口服利奈唑胺 2 个月，然后进行开胸手术和降主动脉置换术。切除的覆膜支架培养物证实了感染。手术后，她恢复得很好，过着平静的生活。主动脉移植物感染是胸主动脉腔内修复术中一种不常见的、具有挑战性的并发症。¹ 18 F- ^FDG PET-CT 已成为一种有用的诊断方式。^{2 ,3}广泛的清创、移植物置换和抗生素的使用对于主动脉移植物感染的治疗至关重要。^{4 ,5}
