Axillary artery to contralateral axillary vein graft fistula in chronic hemodialysis patients.

BACKGROUND: Vascular access failure is a severe and common complication for hemodialysis patients. The possible vascular access sites are limited in dialysis patients. Axillary artery to contralateral axillary vein arteriovenous fistula (AVF) is one of the possibilities. However, the clinical outcome of this procedure is still un-defined.

OBJECT: The purpose of this study is to review the clinical outcome of axillary artery to contralateral axillary vein AVF as a hemodialysis vascular access.

PATIENTS AND METHODS: We retrospectively reviewed native or graft arteriovenous fistula records for chronic hemodialysis patients at Chang Gung Memorial Hospital in Kaohsiung, Taiwan, from January 1986 to March 2001. Records were reviewed for all chronic hemodialysis patients, with more than 2000 individuals receiving more than 10,000 fistulas. Eight patients received axillary artery to contralateral axillary vein AVF.

RESULTS: The mean age for these patients was 61.7 +/- 16.3 year-old at time of surgery. All patients had received multiple native or graft arteriovenous fistula creation. The 2-year and 4-year AVF graft survival is 87.5% and 43.8% respectively. One patients developed brachial plexopathy after operation. Another patient had venous hypertension distal to the AVF site. Both patients were managed conservatively. There is no AVF-related mortality in these patients.

CONCLUSION: We conclude that axillary artery to contralateral axillary vein graft fistula may be a feasible alternative choice for chronic hemodialysis access.
