A ten-year review of aortofemoral graft infection documented Staphylococcus epidermidis as the infecting organism in 18 (60%) of 30 cases. Diagnosis of such infection required a high index of suspicion because of its late postoperative appearance (mean interval of 41 months) and the inability to identify a microorganism at operation by routine wound culture or Gram's stain. Clinical findings suggesting graft infection included multiple anastomotic aneurysms (18 patients), perigraft exudate (16 patients), a draining groin mass (five patients), and aortoduodenal fistulas (two patients). Due to the low concentration and virulence of the organism, aerobic culture of the prosthetic fabric in broth media provided the optimum method of confirming the S epidermidis infection. Total graft excision with immediate vascular reconstruction was the preferred treatment method and resulted in a mortality and major amputation rate of 11%.
一项关于主-股动脉移植感染的十年回顾显示，在30例病例中的18例（60%）中，表皮葡萄球菌被记录为感染病原体。由于这种感染在术后出现较晚（平均间隔41个月），且无法通过常规伤口培养或革兰氏染色在手术时识别微生物，因此对其诊断需要高度的怀疑指数。提示移植感染的临床发现包括多发吻合口动脉瘤（18例患者）、移植周围渗出物（16例患者）、腹股沟引流肿块（5例患者）和主动脉十二指肠瘘（2例患者）。由于该微生物的浓度和毒力较低，在肉汤培养基中对人工血管织物进行需氧培养是确认表皮葡萄球菌感染的最佳方法。完全切除移植血管并立即进行血管重建是首选的治疗方法，其死亡率和大截肢率为11%。
