Abstract: 【Abstract】Objective The aim of this review is to summarize the data in the literature about the first puncture time, patency rate and complications in patients using the novel arteriovenous gifts (AVG) for arteriovenous fistula. Methods Electronic databases including PubMed, MedLine, Cochrane Library (Issue7, 2017), Embase and CNKI before July 2017 were searched for studies about the use of early cannulation grafts for dialysis. According to the inclusion and exclusion criteria, related cohort studies were collected, and data were extracted and cross-checked by two reviewers. The primary outcome in this study was primary patency (PP) rate and secondary patency (SP) rate. The secondary outcome was complication rate of AVGs including thrombosis, hematoma, pseudoaneurysm, infection and steal blood syndrome. Results A total of 20 studies involving 1,230 cases treated with AVGs were included in this systematic review. Four types of AVGs including FlixeneTM, VectraTM, AcusealTM and AvfloTM were used. Most of the AVGs could be used for puncture after the surgery for 3 days, and some of them could be used after the surgery for 48 hours or even for 24 hours. There were no significance differences in patency rate and complications as compared with those using the traditional ePTFE AVG. AcusealTM AVG had the advantage of less thrombosis, and AvfloTM AVG had less infections. Conclusion This review shows that the novel AVGs have the advantages of early puncture within 3 days without impacts on primary patency rates, secondary patency rates and complications.
