Scleroembolization for treatment of hypertension caused by intrarenal arterial fibrodysplasia.

This paper reports a 13-year-old girl with severe hypertension due to fibrodysplasia of intrarenal arterial branches in the upper pole of the left kidney. Scleroembolization of the abnormal vascular region was carried out by injecting, via a transcutaneous catheter, an 80% solution of sodium iothalamate in ethanol, followed by a suspension of Gore-Tex particles in the same solution, which resulted in complete and persistent normalization of blood pressure.
