It is well described and well know; yet again, there is no evidence that it helps in improving latency rate. Things are slightly different on using a synthetic graft. It appears that the patency rate improves primarily (as compared to secondary intervention)
Two randomised controlled trials and seven retrospective cohort studies comprising 966 participants were included. Pooled standardized data showed no difference in primary graft patency (pooled RR = 1.25, 95% CI 0.73–2.16), secondary patency (pooled RR = 1.16, 95% CI 0.82–1.66), or limb salvage at 12-months (pooled RR = 1.13, 95% CI 0.80–1.60) for the peripheral bypass with AVF group compared with peripheral bypass alone. Subgroup analysis indicated a reduction in reintervention rates associated with AVF when performed in conjunction with a synthetic graft (pooled RR = 0.55, 95% CI 0.30–0.98).
