Long-term Outcomes of Brachiobasilic Transposition Fistula for Haemodialysis

AbstractObjectives. The transposed basilic vein to brachial artery arteriovenous fistula provides secondary vascular access for haemodialysis. The long-term results of such fistula are assessed in this retrospective series.Material and methods. Over a 5-year period 75 brachiobasilic transposition fistulae were performed in 74 patients. There was a median follow up of 14 months.Results. Primary patency was achieved in 69 (92%) of the fistulae, and secondary patency in 74 (99%) of the fistulae. Successful interventions included angioplasties in four, and saphenous vein interposition in one, whilst three patients had failed thrombectomies. Dialysis was performed using 69 (92%) of the fistulae while 6 (8%) were never used. Of the 75 fistulae 47 (63%) were patent at follow up. Cumulative secondary patency was 66% at 1 year, 52% at 2 years, and 43% at 3 years. Complications developed in 41 (55%), and included thrombosis, infection, stenosis, arm oedema, bleeding, steal syndrome and microaneurysm formation.Conclusions. Brachiobasilic transposition fistulae have good long-term patency rates. The complication rate, although high, is lower than that reported for PTFE grafts. Brachiobasilic fistulae should be used in preference to PTFE grafts for secondary access
