PURPOSE: To evaluate the role of percutaneous stenting in the treatment of @entity8 after failure of balloon angioplasty. METHODS: Two hundred ten @entity1 (139 males; mean age 67.7 +/- 9.9 years, range 27 to 87) had 259 balloon-expandable stents (165 Palmaz and 94 Renal Bridge stents) implanted in 244 @entity2791 (171 ostial and 73 nonostial lesions). The @entity1 were suffering from intractable @entity101 (n = 210) and/or @entity8 (n = 48). The majority of the lesions (n = 234) were @entity1856 in origin. Stents were implanted for @entity384 (n = 182, 75%), @entity75 (n = 27, 11%), or dissection (n = 9, 4%); 26 (11%) @entity75 were stented primarily. Mean lesion length was 11.9 +/- 4.4 mm (range 5 to 30) and mean percent stenosis was 81.9% +/- 8.25% (range 70 to 100). RESULTS: Immediate technical success was 99% (241 of 244). Three (1.2%) major complications included one intraprocedural stent @entity715 , one arterial perforation manifesting as a perirenal @entity1410 24 hours after the procedure, and one renal @entity397 . Follow-up over a mean 25.4 +/- 22.8 months (range 1 to 96) in 185 eligible @entity1 (209 arteries) found 24 cases of @entity256 (11.4%). Primary and secondary patencies for all lesions at 60 months were 79% and 98%, respectively, with no significant differences between ostial and nonostial lesions or stent types. @entity101 was reversed in 35 (19%), improved in 112 (61%), and remained unchanged in 37 (20%). Renal function was improved in 29% (14 of 48), unchanged in 67% (32 of 48), and worse in 4% (2 of 48). CONCLUSIONS: Renal artery stenting is safe, effective, and may be an alternative to surgery, particularly in @entity75 . Our experience shows @entity256 rate compared to conventional angioplasty. All ostial stenoses should be stented.
