['Although increased application of percutaneous renal artery angioplasty and stenting has facilitated nonoperative renal revascularization, patient outcomes after failed angioplasty are not established.', 'Renal artery revascularization was performed in 31 patients (38 arteries) from 1993 to 1999. Twenty patients underwent primary surgical repair, and 11 patients underwent secondary reconstruction after angioplasty (n = 7) or angioplasty and stenting (n = 4). Before operation, all patients had severe hypertension (blood pressure 166+/-5.2/92 +/- 2.7 mm Hg) that required an average of 3.0 +/- 0.2 medications for control. In addition, 12 patients (primary 45% vs secondary 27%; P = NS) had evidence of renal insufficiency (creatinine > or =1.7 mg/dL).', 'There was no difference between primary and secondary procedures in the length of hospital stay (12+/- 1.4 vs. 12+/-3.2 days; P = NS), major morbidity (10% vs. 18%; P = NS) or perioperative mortality (overall mortality 2 of 31; primary 5% vs secondary 9%; P = NS). The majority of patients demonstrated improvement or cure of hypertension (primary 94% vs secondary 90%; P = NS) and stable or decreased creatinine (primary 74% vs secondary 82%; P = not significant). Overall survival (mean follow-up 22+/-3.5 months) was 89%+/-5.7%.'] Does angioplasty affect subsequent operative renal artery revascularization?
