likely to have VWINGS in use at last follow-up (P < .007). No differences in use were found between clinic providers. A total of 77 (12%) patients had at least one device removed. Reasons for explantation were 28.6% infection, 26% cannulation difficulties, 11.7% device moved, 11.7% no longer needed, 6.5% excessive scarring, and 15.6% unknown. A total of 44 patients (6.7%) had a secondary procedure, not including catheter placement. There were no known fistula failures due to device placement or removal. Fistula survival was 87%. Failure of 84 fistulas (12.8%) occurred an average of 254 days after implantation. Conclusions: VWING devices facilitate cannulation in a difficult dialysis population. Use of the devices is safe and allows use of deep fistulas with smaller incisions than traditional superficialization.
