Complete resolution of acute renal failure after left renal artery angioplasty and stent placement for total renal artery occlusion.

A 25-year-old female, 17 weeks pregnant presented to our hospital with complaints of progressively increasing dyspnea. She was hypertensive with creatine of 1.0; she was transferred to ICU with multiple medications to control her blood pressure, without success. The patient continued to decompensate, which required intubation. The patient developed acute renal failure, part of her work-up suggested bilateral renal artery stenosis. She was taken to the catheterization lab and was found to have bilateral total renal artery occlusion. The left renal artery was successfully opened. The patient recovered and her blood pressure was controlled after the procedure. In the past, surgery was the preferred treatment in cases of acute renal artery occlusion. This approach has been replaced increasingly by renal artery angioplasty, which is less invasive and is at least as effective as surgical reconstruction. Our case demonstrates a percutaneous approach can be tried for totally occluded renal artery with a successful outcome. Copyright 2007 S. Karger AG, Basel.
