Background

With an increasing prevalence of end-stage renal disease and life expectancy of Chinese patients on renal replacement therapy, the quality and availability of superficial vessels can be limited and reduced with time. Arteriovenous access using ePTFE grafts have advantages compared with tunneled cuffed dialysis catheters. Guidelines suggest the usage of ePTFE grafts as access if native fistula is not possible. The aim of our study is to analysis the outcomes of AVGs that we have implanted in our patients.

Methods

We had retrospectively reviewed all the patients who had an AVG during October 2014 to June 2018 in our center. The demographic characteristics,duration of dialysis,laboratory tests, location and configuration of AVG, operation outcome,as well as the patency rate were collected and analyzed.

Results

A total of 262 patients were included in the investigation with the mean age of 60.1±13.8 years old. 56.5% of the study population was female gender. The most common comorbidities were hypertension (83.9%) and diabetes (47.7%). The range of follow-up period was from 10 to 54 months. The configurations of the grafts were 76.7% loop and 23.3% straight, and 62.6% of them were created on forearm. There was no operation-related mortality. Technical successful rate was 100%. However, 3 early failure were noted. The primary and secondary patency rates were 72.8% and 92.3%, 54.5% and 88.8%, 25.6% and 77.8%, 20.9% and 62.3%, 16.7% and 53.3%, at 6, 12, 24, 36, 48months, respectively. There was no difference between the primary and secondary patency of grafts on forearm and upper-arm (p-value: 0.337 and 0.812). The primary and secondary patency of straight grafts on upper-arm was better than loop grafts on upper-arm (p-value: 0.017 and 0.017). These patients required a mean 0.67 interventions per year and there is no difference between the location and configuration of AVGs.

Conclusion

Straight upper-arm AVGs has superiority of primary and secondary patency than loop. Arteriovenous access using ePTFE grafts seems to be an alternative in patients with poor superficial vessels.
