This review article compares the two most commonly used grafts, autogenous saphenous vein and polytetrafluoroethylene (PTFE), for treatment of arterial trauma. Late graft occlusion is more common with PTFE, but PTFE may be better in situations where infection is a concern and extra-anatomic bypass is not possible. When infected, saphenous vein is much more of a risk because of its tendency to undergo sudden hemorrhagic disruption. PTFE grafts usually show only moderate suture line bleeding, which alerts the surgeon to the presence of a problem with the graft.
这篇综述文章比较了治疗动脉创伤最常用的两种移植物，即自体隐静脉和聚四氟乙烯（PTFE）。PTFE发生晚期移植物闭塞更为常见，但在存在感染风险且无法进行解剖外旁路移植的情况下，PTFE可能更具优势。感染时，隐静脉因有突然发生出血性破裂的倾向而风险更高。PTFE移植物通常仅表现为缝线处中度出血，这会提醒外科医生移植物存在问题。
