Radiation-induced Renal Artery Stenosis

Abstract

We present a case of a 33 year old male presenting with uncontrolled hypertension, requiring four drugs and renal dysfunction. Investigations revealed calcific atherosclerosis of abdominal aorta and bilateral renal artery stenosis. He had received radiotherapy for abdominal Non-Hodgkin’s lymphoma 14 years ago. Transluminal angioplasty was done on the right side resulting in improved renal function and normalization of blood pressure. Radiotherapy for intra-abdominal malignancy induces atherosclerosis process in arteries within field of irradiation and they manifest after many years of the initial insult.
