A small, retrospective review of 20 patients who underwent a revascularization procedure (ie, surgery, PTA, PTAS) revealed a high complication rate (increased serum creatinine level in 25%, eosinophilia in 5%, atheroemboli in 15%, renal artery dissection in 5%) despite achieving improved serum creatine values in only 25%. [54] Fifty percent of patients had stable azotemia. The authors conclude that a prospective, randomized trial of medical management with or without PTAS is warranted for this complex clinical problem.
