Our objective was to identify the factors adversely affecting long-term patency after percutaneous transluminal angioplasty (PTA) for hemodialysis Brescia-Cimino @entity2548 . Between November 1995 and March 2000, 91 PTA procedures were performed on 50 @entity1 with 57 Brescia-Cimino @entity292 . A retrospective study based on the chart review was performed. The initial technical success rate for all procedures and the primary and secondary patency rates for all @entity292 were calculated. Regarding @entity292 successfully maintained by the primary PTA, the primary and secondary patency rates were compared using the Kaplan-Meier method between two @entity1 groups. They were classified on the basis of several factors, including age (older, over 70 years, and younger group), age of the @entity292 (older, over 6 months, and younger group), with or without @entity6 ( @entity6 ), solitary or multiple lesions, long or @entity1347 , @entity850 or occlusion, and with or without arterial and/or anastomotic lesions. Initial technical success rates for all procedures and @entity292 were 91.2 and 89.5%, respectively. Cumulative primary and secondary patency rates at 1 year were 47.3 and 67.3%, respectively. In the comparative study, the secondary patency rate for the older group was lower than that of the younger group with statistical significance ( p=0.029). The higher age is the only factor that reduces the long-term patency rate after PTA.
