TITLE: Arteriovenous Grafts' Types of Indications and Their Infection Rate.
BACKGROUND: Arteriovenous graft infection is a well-known and frequent complication. The objective of this study was to compare infection rates of primary and secondary indicated arteriovenous grafts (AVGs).
SUBJECTS AND METHODS: Retrospectively, we evaluated the indications for AVGs created at our institution which became infected. One hundred forty AVGs were evaluated. Of these AVGs, 33 (23.6%) were primary and 107 (76.4%) secondary indicated.
RESULTS:Infection of a primary AVG was detected in 5 patients (15.2 %). Infection of a secondary AVG was detected in 30 patients (28.0%). Primary and secondary patency were significantly lower in patients with infected AVG (P = 0.006; P = 0.0001). The effect of diabetes mellitus and age on development of infection was not confirmed.
CONCLUSIONS:Indications for AVG creation clearly influence the future risk of infection. If the indication to use the AVG is to correct a complicated arteriovenous fistula, the risk of infection is 2 times higher.

背景：动静脉移植物感染是众所周知且频繁发生的并发症。这项研究的目的是比较原发性和继发性动静脉移植物（AVGs）的感染率。
受试者和方法：回顾性地，我们评估了在我们机构中创建的被感染的AVG的适应症。对140个AVG进行了评估。在这些AVG中，有33例（23.6％）为原发性，其中107例（76.4％）为继发性。
结果：5例患者中检出了原发性AVG感染（15.2％）。在30例患者中检测到继发性AVG感染（28.0％）。AVG感染的患者的一期和二期通畅率显着降低（P = 0.006; P = 0.0001）。尚未确认糖尿病和年龄对感染发展的影响。
结论：AVG建立的适应症明显影响未来的感染风险。如果使用AVG的指征是纠正复杂的动静脉内瘘，则感染的风险要高2倍。
启发：AVG感染严重影响AVG的应用，早期识别及预防是至关重要的，必要时进行感染AVG剥除，但影响患者内瘘的正常使用，加重患者的经济负担。
