Background: Between 1980 and 2009, the prevalence of end-stage renal disease (ESRD) increased nearly 600%, from 290 to 1,738 cases per million. Today, it is estimated that over 400,000 ESRD patients require frequent dialysis. The most common dialysis access site today is arteriovenous fistulas (AVF) (55%) followed by AV grafts (AVG) (30%). Dialysis access failure is the leading cause of hospitalization in those patients.
Methods: A prospective protocol was developed. We performed a literature search using PubMed from January 2005 to July 2016. Published studies with the following characteristics were included: 1) comparison of stenting with balloon angioplasty for the management of AVG failure, 2) at least 5 patients examined, 3) manuscript published in English. The type of stent, demographics, graft age and primary patency at 3,6 and 12 months were reviewed
Results: 6 studies (856 patients) were included in our study. The majority of patients received stent grafts and <50 patients received Nitinol stents. 431 patients received stents while 425 balloon angioplasty. The was not statistically significant differences between the stent and the balloon angioplasty groups regarding age (62.0 vs 61.6 years old), male sex (47.6% vs 48.0%), HTN (91.5% vs 91.5%), diabetes (59.9% vs 61.2%) and CAD (37.5 % vs 34.5%). The mean graft age was 2.89 years in the stent group and 3.29 year in the balloon angioplasty group. 3 months primary patency at the stent group was 75.0% vs 57.6% in the balloon group (p:0.004). 6 month primary patency was 55.3% in the stent group and 22.5% in the balloon group (p<0.0001)
Conclusions: AVG failure is a major cause of hospital admission in patients with ESRD who depend on AVF function for hemodialysis. Stent grafts appear to provide superior 3-month and 6-month primary patency compared to balloon angioplasty.
