Abstract: 【Abstract】Objective To summarize the management experience and strategy for the 27 cases with arteriovenous graft (AVG) infections. Methods Clinical data of the 27 patients (11 male cases and 16 female cases) with AVG infections during the period from January 2015 to January 2019 were retrospectively analyzed. The AVGs located in forearm in 16 cases, in upper arm in 7 cases, and in lower limbs in 4 cases. Whole segment infections of the AVG were found in 8 cases, whole segment infections of the AVG with anastomotic pseudoaneurysm in 3 cases, local infections of the AVG in 15 cases, and local infection of the AVG with steal
syndrome in one case. Treatments of the 27 cases included total resection of the AVG with artery reconstruction (13 cases), subtotal resection of the AVG (2 cases), partial resection of the AVG with new graft bypass (11 cases), and partial resection of the AVG with new graft bypass and proximal arterialization of inflow artery (one case). Results All the 27 patients achieved technical success (technical success rate was 100%). No patient died in the peri- operative period. All patients were followed up for an average of 18.3 (12～29) months. During the follow-up period, local infection of the AVG in left upper arm occurred in one case; after subtotal resection of the AVG for two months, rupture of the infected anastomotic orifice at the arterial end of artificial blood vessel and pseudoaneurysm formation in left axillary artery appeared in this case, and the left axillary artery was repaired by autologous basilic vein bypass. One case with local infection of the AVG was treated with partial resection of the AVG with new graft bypass; after the treatment for 8 months, local infection and occlusion of the graft occurred again, and the infected graft was completely resected. Ischemia at the anastomotic orifices and limbs and its related complications (total graft resection) and relapse of graft infec-tions (graft preserved) were not found in other cases. Conclusion Right management strategy should be adopted
according to the types of infected AVG. In principle, the AVG should be preserved as much as possible. The aseptic operation during the operation and the subsequent aseptic technique during the puncture process are essential to reduce the incidence of AVG infections.
