title: The brachio-brachial arteriovenous fistula: mid-term results.
abstract: OBJECTIVE
  To evaluate the mid-term results of the brachio-brachial arteriovenous fistula in patients without adequate superficial venous circulation in the upper limb.
  
  
  METHODS
  Retrospective analysis included 49 patients, in whom a brachio-brachial fistula had been created in an end-to-side configuration. After the maturation period (1 month), the brachial vein was transposed into the subcutaneous tissue. Follow-up study was performed in patients with functional brachio-brachial fistula after the superficialization.
  
  
  RESULTS
  Forty-nine patients underwent 49 brachio-brachial fistula constructions. All fistulas were functional. One month after surgery, 40 (81.6%) of these patients had a functional fistula, but in only 39 (79.6%) cases was the fistula suitable for hemodialysis (HD) following transposition to subcutaneous tissue. During the 1-month maturation period, the fistula became occluded in nine patients, and in one case the vein was permeable, so the fistula was functional, but too small to permit HD. Seventeen patients developed temporary edema of the forearm during the first month, in three cases the edema was extended to the entire arm, but no other complications were associated with the procedure. Follow-up lasted 18.0 +/- 11.1 (3-37) months, during which 7/39 patients presented with fistula occlusion. Three patients died and another three were out of the study for various reasons.
  
  
  CONCLUSIONS
  The brachio-brachial fistula is a good alternative to prosthetic grafts in patients without superficial venous circulation in the upper limb.
