Renal Autotransplantation in a Patient With Resistant Renal Artery Stenosis

Abstract

We report the case of a 5-year-old boy who presented to our hospital with renovascular hypertension (RVH) resulting from right renal artery stenosis (RAS). We performed percutaneous transluminal renal angioplasty (PTRA) on the right RAS. Although hypertension improved after PTRA, restenosis occurred and aggravated hypertension was observed 2 - 3 months later. PTRA was performed again and repeated three times because of restenoses. We subsequently transected the renal arteries and performed renal autotransplantation. The postoperative course was uneventful and hypertension improved. Pathology results showed intimal fibroplasias. More than 1 year and 3 months after transplant, restenosis of the renal artery had not occurred. Successful renal autotransplantation after the frequent PTRA has not been previously reported, and intimal fibromuscular dysplasia (FMD) is rare. Restenosis frequently occurs after PTRA in patients with renovascular hypertension, and renal autotransplantation is an effective treatment in children.
