Acute Hydrophilic-Polymer Nephropathy and Acute Renal Failure

This letter reports a case of acute kidney injury and hydrophilic polymer emboli to the kidneys after a vascular intervention, findings that suggest that iatrogenic embolization of coating from stents may occur. To the Editor: Hydrophilic coatings are used on intravascular devices to facilitate manipulation and to minimize complications such as vasospasm during a procedure and thrombosis after a procedure. 1 , 2 We report a case of vascular intervention associated with acute renal failure in a 42-year-old woman. In 2009, the patient underwent renal transplantation in which the renal artery was implanted into right external iliac artery. Between January and June 2013, her serum creatinine level increased progressively over a 5-month period, from a baseline value of 1.0 mg per deciliter to 2.2 mg per deciliter (normal range, 0.5 to 1.2 mg per . . .
