The purpose of this study was to investigate changes in blood pressure and renal function after percutaneous renal @entity661 in @entity101 @entity1 with @entity2791 . @entity8 were assessed by duplex ultrasound before and after renal @entity661 . Renal arteries were classified as normal, < 60% @entity850 , > or =60% @entity850 , and occluded according to previously validated duplex criteria. Data regarding risk factors for @entity731 and years of @entity101 were collected. @entity551 , @entity1011 , and number of medications were obtained before and after intervention. The immediate technical outcome of renal artery angioplasty was classified based on the arteriographic result as follows: success (residual @entity850 < or =30%), partial success (residual @entity850 31-50%), or unsuccessful (residual @entity850 > 50%). For bilateral procedures, success required both renal arteries to be classified as technical successes; a technical success on one side only was classified as partial success. The blood pressure response to intervention was classified as follows: cure (diastolic blood pressure < or =95 mm Hg on no medications), improved (control of blood pressure with a significant reduction in number of medications or control of previously elevated blood pressure without a change in medications), or failed (all other responses). The study group included 28 @entity1 (14 @entity1 , 14 @entity1 ) with a mean age of 65 years. The preintervention and the first postintervention evaluations occurred within 180 days of the procedure. All @entity1 were @entity101 , and all except one were under medical treatment. Mean duration of @entity101 was 9.1 +/-8.8 years. There were 38 interventional procedures (28 unilateral, 10 bilateral) involving 41 renal arteries; seven arteries had two procedures done. Before angioplasty, all renal arteries had lesions of > or =60% diameter reduction by duplex scanning. Endovascular stents were deployed following angioplasty in 14 (34%) of the procedures. The technical result was classified as a success in 24 (63%), a partial success in 12 (32%) of the procedures, and two procedures (5%) were classed as technical failures. There were statistically significant reductions in blood pressure following successful and partially successful procedures, but cure of @entity101 was achieved in only 11% of cases. There were no significant changes in @entity1011 in any of the technical result groups. Of the 38 renal arteries evaluated with duplex ultrasound following intervention, 39% were found to have @entity850 of > or =0% involving a treated renal artery, including one postintervention occlusion. Cure of @entity101 was rare in this @entity1 population with @entity2791 . More than one third of the treated renal arteries showed > or =0% lesions recurring after the procedure. Thirteen percent of those with technical success and 17% of those with partial technical success had @entity1011 improvement of at least 20% over the baseline value. Significant clinical and anatomic improvement were relatively uncommon @entity661 in this series of @entity1 .
