A case of nonanastomotic pseudoaneurysm of a unilateral axillofemoral bypass graft is reported. The graft material used in this particular instance was an 8 mm, reinforced, thin-walled, fluorinated ethylene-propylene-ringed, expanded polytetrafluoroethylene (ePTFE). The pseudoaneurysm occurred 1 year after insertion of the graft and was not associated with any direct trauma. It manifested with a painful tender mass at the top of the body of the axillofemoral bypass graft at the level of the nipple line. There were no symptoms of localized or diffuse sepsis. Immediate surgical exploration confirmed the diagnosis of a pseudoaneurysm of the ePTFE graft. Successful repair of the disrupted segment was accomplished by use of an interposition, nonringed, reinforced, thin-walled, 8 mm ePTFE graft. To our knowledge this is the first case of a nonanastomotic pseudoaneurysm of a ringed, ePTFE, axillofemoral bypass graft not associated with direct trauma.
本文报告了一例单侧腋股旁路移植血管非吻合口假性动脉瘤的病例。该病例中使用的移植材料是一根8毫米的、增强型、薄壁、含氟乙烯丙烯环的膨体聚四氟乙烯（ePTFE）。假性动脉瘤在移植血管植入1年后出现，与任何直接创伤无关。它表现为在乳头线水平的腋股旁路移植血管体顶部有一个疼痛性压痛肿块。没有局部或弥漫性脓毒症的症状。立即进行的手术探查证实了ePTFE移植血管假性动脉瘤的诊断。通过使用一段8毫米的、非环型、增强型、薄壁的ePTFE移植血管进行置换，成功修复了破裂段。据我们所知，这是首例与直接创伤无关的带环ePTFE腋股旁路移植血管非吻合口假性动脉瘤病例。
