Vascular access outcomes using the transposed basilic vein arteriovenous fistula
2003
Abstract Background: Although the transposed basilic vein arteriovenous fistula (TBAVF) is increasingly performed for hemodialysis vascular access in patients 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 patients who had a TBAVF 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 patients, mean age was 55 years, and 46% were men. Unassisted and assisted patency rates were 47% and 64% at 1 year and 41% and 58% at 2 years, respectively. Primary access failure occurred in 23% of cases. Unassisted access patency was significantly worse in patients 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 P P P = 0.01). Steal syndrome requiring intervention occurred in 5% of cases. Conclusion: In summary, the TBAVF provides a viable option for vascular access; however, certain patient characteristics seem to affect long-term patency and should be considered when exploring access options.
