Alternatives for exhausted dialysis access.

Hemodialysis (HD) access failure is a frequent problem encountered by vascular surgeons. As treatment of end-stage renal disease improves and patients live longer on HD, eventual exhaustion of traditional upper extremity HD access is common. Efforts to preserve and maintain these accesses are essential. However, when they fail, alternative surgical access options should be pursued prior to destination-tunneled dialysis catheters. Hemodialysis Reliable Outflow grafts as well as various configurations of lower extremity arteriovenous fistulae and grafts can be utilized. For most alternative HD access options, there is a paucity of data for long-term patency, cost, and risk of infectious or ischemic complications compared to traditional options. However, smaller studies examining Hemodialysis Reliable Outflow grafts, femoral vein transposition, and lower extremity grafts show acceptable safety and efficacy. Depending on the cause of traditional access failure and patient-specific anatomic constraints, we recommend a systematic approach to alternative access creation, with destination-tunneled dialysis catheters reserved as a last resort. The most common cause of HD access failure is venous outflow obstruction. As such, we have structured this manuscript around a meta-analysis of retrospective studies describing nontraditional access options that can be utilized with escalating degrees of central venous stenosis or occlusion.
