Chan, MP (28)Retrospective200721191% versus 80% at 30 d, 69% versus 24% at 90 d, and 25% versus 3% at 180 for AVGN/AThe primary assisted AVF patency did not differ significantly between the stent and angioplasty groups.
Vesely, TM (27)Retrospective20077081%, 70%, and 54% at 1, 3, and 6 mo for PTA, respectively,89%, 82%, and 74% at 3, 6, and 12 mo for stent, respectivelyMultiple stent types
96%, 93%, 87%, and 47% at 1, 3, 6, and 12 mo for stent, respectively
Maya ID (28)Retrospective200648median survival, 85 versus 27 d, P = 0.02median survival, 1215 versus 46 days, P = 0.049Thrombosed AVG only
Vogel PM (24)Prospective, non-randomized2005605.6 mo after PTA and 8.2 mo after stent treatment (P = 0.050)N/A
Haage P (35)Observational (no control group)1999503-, 6-, 12-, and 24-mo rates were 92%, 84%, 56%, and 28%, respectively97% after 6 and 12 mo, 89% after 24 mo, and 81% after 36 and 48 mo
Hoffer EK (13)Prospective, randomized199737Primary patency of 128 d and secondary patency of 431 d were similar for both groups.Secondary patency required a mean of 1.8 and 1.6 additional interventions for the PTA and stent groups, respectively.The adjunctive stent placement increased the cost of the procedure by 90%.
Quin SF (11)Prospective, randomized199587PTA at 60, 180, and 360 d were 55%, 31%, and 10%, respectively, and for stents were 36%, 27%, and 11%, respectively (P = 0.6528)PTA at 60, 180, and 360 d were 94%, 80%, and 71%, respectively, and for stents were 73%, 64%, and 64%, respectively (P = 0.1677)No difference between stent and PTA was found.
