PURPOSE: To determine if there is a difference in intervention patency for @entity1211 ( @entity1211 ) and occlusion between @entity1 with autogenous hemodialysis @entity292 and those with grafts. MATERIAL AND METHODS: A retrospective study was performed from March 1998 to September 2005 identifying all @entity1 with autogenous @entity292 and synthetic grafts who underwent percutaneous angioplasty and/or stent placement for @entity1211 . This study cohort consisted of 38 @entity1 (22 with @entity292 and 16 with grafts). Age, sex, type of access, location and side of the access, location and side of the @entity1211 , presence of @entity6 , previous hemodialysis catheter placement, date and type of interventions, and outcomes were recorded. The patency of each intervention was estimated by using the Kaplan-Meier survival curves. Univariate and multivariate analysis of the variables were performed. RESULTS: Eighty-nine interventions were performed; 83 were angioplasties and six were stent placements. Previous catheter placement on the side of the @entity1211 occurred in 29 of the 38 @entity1 (76%). Technical and clinical success of the interventions were 93.3% and 94.4% respectively. The intervention or primary patency rates +/- standard errors at 3, 6, and 9 months in the fistula group were 88.5% +/- 4.8, 59.4% +/- 7.6, and 46% +/- 7.9, respectively. In the graft group, the rates were 78.1% +/- 7.3, 40.7% +/- 9, and 16% +/- 7.3, respectively. With multivariate analysis, intervention patency remained significantly longer for @entity292 (P .014) and in @entity1 who did not have a previous catheter (P .001). CONCLUSION: Longer intervention-free survival for @entity1211 was observed in @entity1 with autogenous @entity292 compared with grafts and in @entity1 who did not previously undergo hemodialysis catheter insertion.
