Two-stage basilic vein transposition-a new approach for pediatric dialysis access

Abstract

Purpose: The fistula first initiative has led to increased efforts to create arteriovenous fistulas (AVFs) as primary dialysis access. Two-stage basilic vein transposition (BVT) allows maturation of smaller veins, often a limiting factor in the pediatric population, before elevation and use. We sought to determine whether using 2-stage BVT improves maturation, use, and patency compared with other AVFs, including arteriovenous (AV) grafts.

Methods: Thirty-one patients underwent AV access creation between 1997 and 2008. Data were collected on types of access, maturation, complications, and patency.

Results: Forty-two AV access procedures were performed: 15 (36%) 2-stage BVT, 13 (31%) 1-stage BVT, 6 (14%) radiocephalic, 3 (7%) brachiocephalic, 1 (2%) brachiobrachial, and 4 (10%) AV grafts. Follow-up averaged 20.4 +/- 3.2 months for 2-stage BVT and 47.9+/-4.1 months for other AVFs (P < .001). All 2-stage BVT matured compared with 52% (14/27) of other AVFs (P = .001). More 2-stage BVTs (87%) were used for dialysis than other AVFs (48%, P = .024). Fistula failure occurred in 7% 2-stage BVT compared with 59% other AVFs (P = .001). One-year patency rates were 91% for 2-stage BVT vs 47% for other AVFs (P = .003).

Conclusions: Rates of fistula maturation, use, and patency are higher for 2-stage BVT with lower rates of failure. Two-stage BVT shows great promise as the preferred approach to creation of AVF in pediatric patients, especially those with smaller veins.
