ResumoThere have been numerous reports on renal angioplasty and stenting that have opposing results and opinions.1–5 Long-term hypertension may cause nephrosclerosis6 or glomerulosclerosis,7 and increase vascular resistance.8 Treatment of the renal artery is unlikely to improve perfusion in patients with increased microvascular resistance, and such patients are unlikely to obtain clinical benefit. Radermacher et al9 demonstrated that a renal artery resistance index (RI) has good predictive value in identifying patients who are unlikely to benefit from renal revascularization. In this study, we evaluated whether renal artery peak systolic (PSV) and end-diastolic (EDV) velocities and the renal artery RI can predict outcomes after renal artery stenting.
