Abstract: 【Abstract】Objectives To summarize our experience about the operation method for below-the-elbow arterio-venous fistulas (BEAVFs) and its clinical effects. Methods We retrospectively analyzed the maturation, patency and complications of the BEAVFs performed between October 2005 and December 2010 in this department. Results A total of 62 cases (41 males and 21 females; mean age 56.06±17.83 yrs) were treated with the anastomosis of proximal radial (or ulnar) artery and the median cubital vein (or its perforator vein). BEAVFs were successfully established in all patients without complications including hematoma, wound infection, high output cardiac failure, steal blood syndrome and perioperative mortality. The BEAVFs were functionally useful for hemodialysis access after the operation for 1-2 months. After the operation for one and two years, the patent rate was 98.1% and 96.3%, respectively. Conclusions BEAVF is a new method better than the brachial artery in-flow AVF. This method has the advantages of less injury, heart failure, steal blood syndrome and arm edema, a longer and straight conduit for vascular access, and a high patency rate.
