Long-term harm associated with renal artery stents in a temporally distant time after the renal function is gone

Abstract

Although large randomized trials have not shown significant benefit of renal artery stent placement, stents continue to be placed in patients with Renal Artery Stenosis (RAS). These intravascular foreign bodies can cause cytokine expression that might result in long-term harm. We evaluated the possibility that they could have adverse effects that were both temporally and spatially distant from their insertion.
