In the absence of suitable cephalic vein, the brachiobasilic vein complex represents the best option for arteriovenous access. However, the basilic vein is too deep to cannulate and requires transposition to be accessible. Transposition can be performed during fistula creation (single-stage BBTx) or at a second operation after initial fistula creation (two-stage brachiobasilic transposition (BBTx)). The best approach is unknown. A PubMed search using "Basilic vein transposition" as the primary search term was performed to identify articles addressing this controversy. Meta-analysis was then performed using those papers that provided the inspected data points with student's t-test used to compare maturation and patency rates between the groups. A total of 37 manuscripts were judged of adequate quality for analysis. Based on the available data, overall maturation rates, 1-year primary patency rates, and overall complication rates seem to be equivalent between single- and two-stage BBTx, while 1-year secondary patency is greater in the two-stage group (79% vs 85%). A large prospective randomized clinical trial with clear definitions of maturity, patency, and complications is needed to definitively answer the question of whether one strategy is better than the other. |
