BACKGROUND: Although the @entity2548 ( @entity2548 ) is increasingly performed for hemodialysis vascular access in @entity1 lacking adequate superficial veins, little is known about the long-term patency or risk factors for failure. METHODS: A retrospective analysis was conducted for 99 @entity1 who had a @entity2548 created between April 1997 and October 2001. Primary outcomes were unassisted and assisted patency rates and primary failure rates. RESULTS: This was the first access procedure in 46% of @entity1 , mean age was 55 years, and 46% were @entity1 . Unassisted and assisted patency rates were 47% and 64% at 1 year and 41% and 58% at 2 years, respectively. @entity177 occurred in 23% of cases. Unassisted access patency was significantly worse in @entity1 with a previous access (relative risk [RR], 2.04; confidence interval [CI], 1.09 to 3.85; P = 0.03) or an ipsilateral central venous catheter (RR, 2.92; CI, 1.34 to 6.38; P < 0.01). @entity177 was affected by older age (RR, 2.0; CI, 1.20 to 3.38; P < 0.01), @entity28 (RR, 7.1; CI, 1.65 to 30.1; P < 0.05), and a previous vascular access (RR, 6.4; CI, 1.49 to 27.6; P = 0.01). @entity3526 requiring intervention occurred in 5% of cases. CONCLUSION: In summary, the @entity2548 provides a viable option for vascular access; however, certain @entity1 characteristics seem to affect long-term patency and should be considered when exploring access options.
