Renal artery thrombosis caused by stent fracture: the risk of undiagnosed renal artery entrapment.

We report a case of renal artery thrombosis resulting from a stent fracture in a patient with a solitary functional kidney. It was successfully revascularized by surgical repair despite renal ischemia lasting more than 48 hours. This article illustrates the danger of generalizing endovascular stenting in renal artery disease regardless of the etiology. Renal artery entrapment must be kept in mind as a possible cause of renal artery stenosis. Treatment of compressive pathologies with stenting can lead to stent failure. Surgery remains the best approach for the treatment of this type of lesion.
