Bloch and Basile identified risk factors which can help identify a patient with renal arterial stenosis who may have a poor outcome to a vascular intervention such as a stent placement or percutaneous angioplasty. The authors are from the University of Nevada and the Medical University of South Carolina.

The presence of one or more of these findings may help identify a patient with progression or no improvement after the vascular intervention.
