Acute renal artery occlusion: making the case for renal artery revascularization

Atherosclerotic renal artery disease is a common disease entity that may be identified in patients with difficult-to-control hypertension and/or chronic kidney disease but is probably underdiagnosed. Current evidence from both observational and randomized studies offers mixed results regarding the support for renal artery revascularization. There is lack of equipoise with regard to the efficacy of renal artery revascularization among the interventional and renal communities, as well as disagreements on the appropriate endpoints to measure in clinical trials, which have led to selection bias confounding the scant available data. We report a patient who does not fit any clinical trial inclusion criteria with acute on chronic kidney injury and new-onset heart failure whose symptoms and renal function improved significantly after renal artery intervention.
