Delayed superficialization of brachiobasilic fistula: technique and initial experience

HYPOTHESIS: Angioaccess procedures for dialysis have varied patency rates with frequent need for intervention. A superficialized arteriovenous brachiobasilic fistula created as a 2-step procedure will have good long-term patency with minimal complication. DESIGN: Retrospective medical record review and patient interview. SETTING: Tertiary referral university hospital. PATIENTS: Twelve patients who underwent delayed superficialization of brachiobasilic fistula from September 1994 to April 2000. MAIN OUTCOME MEASURES: Patency of fistula for dialysis, and major and minor complications, including revisions. RESULTS: Delayed superficialization of brachiobasilic fistula was performed in 12 patients. Fistulas have been used for a mean duration of 22.4 months (range, 10-59 months). Two patients required alternate access owing to thrombosis of brachiobasilic fistula. CONCLUSIONS: The delayed superficialized brachiobasilic arteriovenous fistula has a good initial patency rate with minimal complications. It should be considered early in patients if radiocephalic fistula is unavailable.
