Staphylococcus epidermidis has been implicated as a major etiologic agent of delayed synthetic vascular graft infection and/or pseudoaneurysm formation at the femoral anastomosis. The source of possible operative graft contamination is debated. Forty-five inguinal incisions in consecutive patients undergoing elective peripheral revascularization were studied. No opening cultures were positive: 30 per cent showed positive nodal cultures; 25 per cent showed positive arterial wall cultures; and 20 per cent showed positive closing cultures, 95 per cent of which were S. epidermidis. There was no correlation with preoperative transfemoral angiography. This high incidence in the tissues of the inguinal incision may be related to the delayed development of S. epidermidis graft infections.
表皮葡萄球菌被认为是延迟性人工血管移植感染和/或股动脉吻合处假性动脉瘤形成的主要病因。手术中人工血管可能的污染来源存在争议。对连续接受择期外周血管重建术的患者的45个腹股沟切口进行了研究。切口处培养物均为阴性；30%的患者淋巴结培养物呈阳性；25%的患者动脉壁培养物呈阳性；20%的患者切口闭合时培养物呈阳性，其中95%为表皮葡萄球菌。这与术前经股动脉血管造影无关。腹股沟切口组织中的高感染率可能与表皮葡萄球菌移植感染的延迟发生有关。
