OBJECTIVE: @entity2548 ( @entity2548 ) are commonly used during hemodialysis. Early failure of @entity2548 is quite common with incidence of 43% to 63%. In this study we aimed to describe a novel approach to AVF surgery for improving early patency rates. @entity1 AND METHODS: @entity1 were divided into two groups according to use of probing and warm-wash-out technique. Group I consisted of 31 @entity1 with additional probing technique. Group II consisted of 32 @entity1 without additional maneuver. End-to-side @entity254 were used to all @entity1 . Technical success was defined as having palpation of a thrill on @entity292 . Flow rates of draining vein was measured at 1st hour, 24th hour, 1st week and 3rd week of surgery. SURGICAL TECHNIQUE: Classical maneuvers were performed until end of the @entity254 . At this time, vein lumen was washed by low-dosed heparinized warm fluid, with assistance of a simple catheter. RESULTS: Technical success was similar in both groups at 1st hour and 24th hour, while there were significantly differences between groups at 1st week (p = 0.042) and 3rd week (p = 0.05) assessments. Flow rates were also measured significantly higher in Group I at 1st hour (p = 0.011) and 24th hour (p = 0.016). Flow rates were almost similar in two groups at 1st and 3rd weeks but overall success rate was higher in Group I comparing with Group II (96.8% vs. 81.3%, respectively, p = 0.05). CONCLUSIONS: Probing and warm-wash out technique will simply increase the surgical success and flow rate of draining vein.

New probing and warm-wash-out technique improves early patency rates in XXXX surgery.
