Renal artery revascularization: Outcomes stratified by indication for intervention

Primary Patency. Kaplan Meier curves plotting the fraction of grafts or stents patent or free of critical stenosis over time. The solid line represents patency in patients treated with open surgical renal artery revascularization and the dashed line represents the patency of endovascular revascularization. Arrows delineate when the standard error exceeds 10%.

Survival. Kaplan Meier curves plotting the fraction of the study population alive over time. The solid line represents survival in patients treated with open surgical renal artery revascularization and the dashed line represents the survival of patients treated endovascularly. Arrows delineate when the standard error exceeds 10%.

Assisted Primary Patency. Kaplan Meier curves plotting the fraction of grafts or stents patent over time. The solid line represents patency in patients treated with open surgical renal artery revascularization and the dashed line represents the patency of endovascular revascularization. Arrows delineate when the standard error exceeds 10%.

Freedom from Reintervention. Kaplan Meier curves plotting the fraction of grafts or stents requiring an intervention to maintain patency or reverse clinical deterioration. The solid line represents reintervention in patients treated with open surgical renal artery revascularization and the dashed line represents reintervention in patients treated endovascularly. Arrows delineate when the standard error exceeds 10%.

Dialysis-free Survival. Kaplan Meier curves plotting the fraction of the study population alive and with preserved renal function over time. The solid line represents freedom from dialysis in patients treated with open surgical renal artery revascularization and the dashed line represents the freedom from dialysis in patients treated endovascularly. Arrows delineate when the standard error exceeds 10%.
