OBJECTIVE. The objectives of our study were to review the appearances on diagnostic imaging and amenability to imaging-guided intervention of a novel bovine ureter graft (Syner-Graft 100 [SG 100]) for use as a conduit for hemodialysis fistulas.

CONCLUSION. The SG 100 shows initial promise as a conduit for hemodialysis fistulas in patients with difficult vascular access. The SG 100 has characteristic appearances on diagnostic imaging and is prone to similar pathologic processes that affect autogenous venous and synthetic grafts. These grafts are readily amenable to imaging-guided percutaneous intervention, which plays a major role in prolonging graft function.
